DC-motorns arbetsprincip
The EP-XL22ZX operates on the well-established permanent magnet DC motor working principle. A fixed arrangement of rare-earth permanent magnets creates a static magnetic field within the motor housing. When direct current is supplied to the wound armature through carbon brushes and a commutator, the interaction between the armature's electromagnetic field and the stator's permanent field produces a rotational force — torque — at the output shaft. The commutator automatically reverses current direction in each armature coil as it crosses the magnetic neutral axis, sustaining continuous rotation without the need for external commutation electronics.
This architecture makes the permanent magnet DC motor inherently straightforward to control: output speed varies proportionally with supply voltage, and torque varies proportionally with armature current. For an oil pump motor application, this means that the gear oil pump flow rate can be regulated directly by varying the supply voltage — a feature widely exploited in load-sensing hydraulic circuits on mobile equipment. The high torque DC motor characteristic of the XL22ZX design ensures that peak oil flow is available immediately at motor start, without a ramp-up period, which is critical in lift and dock leveller applications where actuation response time determines operational throughput.
The Class F winding insulation allows continuous operation at winding temperatures up to 155°C, providing adequate thermal headroom for the 2-minute S2 and 10% ED S3 duty cycles characteristic of hydraulic oil pump motor service on vehicle power units. The commutator and brush assembly is dimensioned for the 125 A rated current, with brush grade and spring pressure optimised for the combination of current density and surface speed at the commutator that this motor's rated operating point produces.
Fem viktiga produktfördelar
High Torque at Low Voltage
At 24V supply, the XL22ZX delivers 8 N·m of rated torque — a power density that significantly exceeds many competing electric oil pump motor designs in the same voltage and frame size class. This high torque DC motor characteristic means the oil pump reaches operating pressure quickly on each actuation cycle, reducing total lift time on scissor lifts and dock levellers.
IP54 Environmental Protection
The IP54 waterproof rating ensures protection against dust ingress and water splashing from any direction. This is a practical necessity for oil pump motor assemblies mounted in undercarriage positions on boarding trucks, vehicle-mounted platforms, and outdoor dock equipment that are routinely exposed to wash-down water, road spray, and dusty industrial environments.
Class F Thermal Rating
Class F insulation rated to 155°C provides a substantial thermal margin above the winding temperatures generated during rated-duty operation, extending brush and commutator service life and reducing the risk of insulation degradation from thermal cycling — a common cause of premature failure in intermittent-duty small oil pump motor applications on high-cycle equipment such as dock levellers and vehicle lift gates.
Compact Axial Footprint
With an overall length of 181 mm and a body diameter of 90.5 mm, the EP-XL22ZX fits within the envelope constraints of most standard 24V hydraulic power unit enclosures without requiring housing redesign. This dimensional compatibility makes it an effective oil pump motor replacement for worn-out units in existing equipment without mechanical modification to the mounting bracket or coupling arrangement.
Simple Terminal Wiring Layout
The A1 and D2 terminal arrangement follows a widely adopted DC motor wiring convention, making the EP-XL22ZX compatible with the majority of 24V motor controllers and contactor-switching circuits used in lift and vehicle power unit applications. OEM assemblers and field service technicians in the USA, UK, Germany, and Australian markets can connect the motor without proprietary connectors or adaptor harnesses in most standard applications.
Materials and Construction Quality
The EP-XL22ZX oil pump motor is constructed from materials selected to meet the combined demands of high current density, intermittent thermal loading, mechanical vibration, and environmental exposure characteristic of mobile hydraulic applications. The motor housing is formed from precision-cast aluminium alloy, providing a favourable strength-to-weight ratio that keeps the oil pump motor assembly weight within the envelope requirements of mobile vehicle equipment while maintaining adequate rigidity to resist shaft deflection under radial gear loads from the hydraulic pump drive gear.
The armature core is laminated from high-grade silicon steel, with lamination thickness and slot geometry optimised for the 24V operating frequency range of this motor. Silicon steel lamination limits eddy current losses, which would otherwise generate excess heat in the armature core during the intermittent duty cycles — an important consideration in small oil pump motor designs where the surface area available for convective heat dissipation is limited relative to the power dissipated in the winding. The armature winding uses copper conductors wound to a defined fill factor that balances current-carrying capacity against slot area constraints.
The commutator is machined from a copper alloy bar stock with a silver content specification that extends brush film formation quality at the contact surface, reducing brush wear rate at 125 A operating current. Carbon brush grade is selected for the combination of current density and peripheral speed present at this motor's rated operating point. The permanent magnets in the stator assembly are high-coercivity ferrite or rare-earth NdFeB depending on the configuration variant, retained by a bonding and mechanical retention system that maintains magnet position and field strength over the thermal cycling and vibration exposure of the intended application life.
Applikationsscenarier
The EP-XL22ZX 2200W 24V oil pump motor is suited to any application that requires a compact, high-torque electric oil pump motor operating from a 24V DC supply in an intermittent duty cycle. The following categories represent the primary deployment environments for this unit worldwide.
Vehicle Power Units
Hydraulic power units mounted on trucks, trailers, and specialist vehicles use the XL22ZX as the drive motor for the gear oil pump with motor assembly that supplies hydraulic pressure to tipping, clamping, or extension actuators. The motor's 24V rating aligns with standard heavy vehicle electrical systems, and its compact body fits within the underbody or cab-mounted power unit enclosures typical of European and North American truck auxiliary hydraulic installations.
Scissor Lifts and Dock Levellers
In battery-powered scissor lift and dock leveller platforms, the XL22ZX drives a small gear oil pump motor assembly that generates the hydraulic pressure required to raise the scissor mechanism against load. The 2-minute S2 duty cycle matches the typical raise time of these platforms, and the high rated torque ensures adequate pressure for rated platform capacity across the full extension range, including maximum extension against rated load where hydraulic pressure demand peaks.
Boarding Trucks and Air Stairs
Airport ground support equipment — particularly mobile boarding stairs and passenger boarding bridges — uses 24V DC hydraulic oil pump motor sets to extend and retract the stair assembly and adjust platform height. The XL22ZX's IP54 rating and compact geometry suit the outdoor, corrosion-prone environment of airport aprons, and its high torque DC motor output handles the high hydraulic pressures needed for stair extension under passenger load.
Specialised Industrial Equipment
The motor oil pump set configuration of the XL22ZX is also deployed in industrial equipment categories including injection moulding machine hydraulic circuits, steel-frame tilting tables, welding positioners, and industrial die-handling carts where a self-contained 24V hydraulic power source — supplied by batteries or a vehicle electrical system — is preferred over a mains-connected hydraulic station for mobility or safety reasons.

Vanliga frågor
What is an oil pump motor and how does it work in a hydraulic lift system?▼
An oil pump motor is a DC electric motor — typically a permanent magnet or series-wound type — that directly drives a gear oil pump or vane pump to generate hydraulic pressure in a self-contained power unit. In a scissor lift or dock leveller application, the motor receives a voltage signal from a control contactor or motor controller, rotates the pump gear at the motor's output speed, and the pump displaces hydraulic fluid from a reservoir into the actuator circuit. When the motor is de-energised, a solenoid-controlled valve holds the actuator in position until a lowering signal is received. The EP-XL22ZX operates on this principle at 24V, 125A, producing the 8 N·m of torque required to drive the pump against maximum system pressure.
Which oil pump motor replacement fits a 24V dock leveller or scissor lift hydraulic power unit in the USA or Canada?▼
For a 24V hydraulic power unit in a North American dock leveller or scissor lift platform, the EP-XL22ZX is a compatible replacement candidate when the original motor specification falls in the 2000–2500W power range at 24V with a rated current below 130A. Before ordering, confirm the overall motor length (181 mm for the XL22ZX), body diameter (90.5 mm), mounting hole pattern (85 mm × 58.5 mm), and shaft tooth count (9 teeth) against the existing pump coupling and mounting bracket dimensions. The clockwise rotation direction and A1/D2 terminal arrangement should also be verified against the existing wiring schematic.
How do I choose between a small oil pump motor and a high torque oil pump motor for a mobile vehicle power unit application in Australia?▼
The choice depends primarily on the maximum hydraulic pressure and flow rate your vehicle power unit needs to generate, and the available supply voltage and battery capacity. A small oil pump motor in the 500–1000W range suits low-pressure, low-flow circuits on lightweight mobile equipment where battery capacity is limited. For heavier-duty applications — tipper truck hydraulics, boarding truck platforms, or lift gates with rated capacities above 500 kg — a high torque DC motor in the 2000W-plus range, such as the EP-XL22ZX at 2200W, is necessary to generate adequate pump pressure against the load. In Australian truck and trailer applications, 24V is the standard supply voltage, making the XL22ZX a direct-fit choice for the majority of existing vehicle hydraulic platform designs.
What does IP54 protection mean for a hydraulic oil pump motor installed on outdoor industrial or airport ground support equipment?▼
IP54 is an ingress protection rating defined under IEC 60529. The first digit, 5, indicates that the motor is protected against dust ingress to a level that prevents dust from entering in quantities sufficient to interfere with satisfactory operation — though not a completely dust-tight seal. The second digit, 4, indicates protection against water splashing from any direction. For airport ground support equipment operating on aprons exposed to rain, wash-down, and jet blast, and for dock equipment in loading bay environments where pressure washing is routine, IP54 provides a practical level of environmental protection for the oil pump motor's electrical components. Equipment operating in submersed or high-pressure wash-down environments would require a higher IP rating (IP65 or above).
Where can I source a reliable gear oil pump motor set or electric oil pump motor assembly for a European boarding truck or vehicle lift gate application?▼
For European boarding truck or vehicle lift gate hydraulic systems requiring a 24V DC oil pump motor assembly, the EP-XL22ZX can be sourced as a standalone motor or as part of a complete gear oil pump with motor assembly matched to the required pump displacement and pressure rating. When evaluating suppliers, request full technical documentation including motor test records, dimensional drawings, wiring diagrams, and the ISO 9001 quality certification that covers production.
