EP-XL22FD 2200W 24V Oil Pump Motor
The EP-XL22FD is a flat-drive oil pump motor delivering 2200W at 24V DC, designed specifically for hydraulic pump circuits where axial compactness and a direct flange-drive interface take priority over overall motor length. Unlike conventional cylindrical motor housings, the XL22FD-24V features a reduced overall length of 167 mm combined with a wider-diameter mounting face, making it the preferred choice when installation depth is restricted — a common constraint in tail-lift sub-frames, compact power pack enclosures, and under-deck vehicle platforms. The 2-tooth spline output and Ø98.5 mm frame allow direct engagement with matched gear pump inputs, eliminating the need for intermediate couplings or adapters in the drive train.
Optional configurations in 12V and 48V extend its usefulness across a wider range of existing battery architectures without altering the mechanical footprint.

Five Defining Strengths of the EP-XL22FD Oil Pump Motor
At just 167 mm overall length, the XL22FD-24V is significantly shorter than equivalent-power round-frame motors. This axial compactness makes it the go-to electric oil pump motor whenever installation depth is a binding constraint — sub-frame tail lifts, underbody power packs, and tight-clearance industrial enclosures where a longer motor simply will not fit without costly structural modifications.
The 2-tooth spline output shaft mates directly with the female drive socket of compatible hydraulic gear pumps, creating a rigid, zero-backlash torque path. Compared to a jaw or spider coupling interface, this arrangement eliminates an additional component, reduces the chance of misalignment-induced vibration, and keeps the oil pump motor assembly total axial envelope as short as possible.
An 8 N·m rated torque figure at 24V puts this high torque dc motor well into the bracket required for medium-duty hydraulic actuation — scissor lifts, dock levellers, and boarding-ramp cylinders. The high torque output also provides reserve capacity during cold starts when oil viscosity is elevated and pump back-pressure momentarily exceeds the steady-state working level, reducing the risk of stall.
IP54 certification means the motor is tested to withstand dust ingress and multi-directional water splashing. For mobile equipment working outdoors in rain, agricultural spray environments, or near washdown areas, this protection level ensures the motor's commutator and brush system remain isolated from contaminants that would otherwise shorten brush life and increase commutation arcing.
Standard production is 24V, but both 12V and 48V variants are available on request. For OEMs building equipment across different regional markets — where 12V systems dominate North American light-duty trucks while 24V and 48V architectures are more common in European commercial vehicles and industrial AGVs — this configurability means a single mechanical design supports multiple product lines without retooling or re-qualifying the pump interface.
How the EP-XL22FD Oil Pump Motor Operates
The EP-XL22FD is a brushed permanent magnet dc motor, and the dc motor working principle that governs it is well-established: direct current applied between terminals A1 and D2 drives current through the wound armature. The stator carries high-coercivity permanent magnets arranged around the armature circumference, creating a stable, uniform magnetic field that requires no external excitation supply. The interaction of this fixed field with the current-carrying armature conductors generates a tangential (Lorentz) force on each conductor. Summed across the full armature winding, these forces produce the rotational torque that spins the output shaft and drives the connected gear pump.
What distinguishes the flat-drive configuration from a conventional tubular motor is the relationship between the armature diameter and length. In the XL22FD, the designer has chosen a larger-diameter, shorter-length armature — sometimes described as a pancake or disc-form factor. A wider diameter increases the moment arm over which the Lorentz forces act, so for a given ampere-turns product, more torque can be generated within a shorter axial envelope. The trade-off is a larger frontal footprint, but in most mobile hydraulic applications the radial space around a pump mounting face is less constrained than the available axial depth, making this geometry the practical winner.
Speed regulation in this motor follows the same back-EMF relationship as any DC machine: as rotational speed increases, the back-electromotive force rises and limits armature current, naturally stabilising output torque against the load. The performance curves for the XL22FD-24V show peak efficiency above 80% in the 3000–4500 RPM band under mid-range torque loads. The S2 / 10% ED intermittent-duty rating bounds the permissible on-time per cycle, ensuring winding temperatures stay within the Class F limit of 155 °C even during repeated start events with cold oil creating elevated pump back-pressure.
Materials & Engineering Construction of Oil Pump Motor
The front and rear housing castings of the EP-XL22FD are machined from die-cast aluminium alloy on CNC vertical machining centres. The casting process produces a near-net-shape blank with consistent density, which is then bored, faced, and drilled to tight geometric tolerances in a single datum setup — ensuring the coaxiality of the output shaft, the mounting face register, and the bearing bores is maintained within tenths of a millimetre. This precision matters because misalignment at the pump coupling causes uneven radial loading on the output bearing, which shortens bearing life and introduces vibration into the hydraulic circuit.
The armature core consists of stacked silicon steel laminations punched to a thickness tolerance of ±0.01 mm. At the rotational speeds this motor achieves, even a modest percentage increase in eddy-current losses would raise operating temperature noticeably; the thin lamination stack keeps those losses low, directing more of the electrical input into useful mechanical work. Armature coils are wound from enamelled copper wire with a temperature index matched to Class F service, and the slot insulation system uses polyester film liners for mechanical protection of the winding during the coil-insertion process.
The commutator is built from hard-drawn electrolytic copper segments with mica insulation between segments, ground to a running surface finish that minimises brush wear. Carbon brush grades are carefully selected for the current density, commutator surface speed, and humidity range the motor is expected to encounter across its intended operating territories — European outdoor environments and North American industrial floors present different humidity and particulate profiles that affect the oxide film quality on the commutator surface, and the brush grade accounts for these differences. All major components are processed under ISO 9001:2015 certified quality controls from incoming goods inspection through final functional testing.

سناریوهای کاربردی
The flat-drive format of the EP-XL22FD opens application doors that a longer cylindrical motor cannot access. Below are the principal sectors where this specific motor geometry is specified and why it earns its place there.
Tail lifts fitted to low-loader and refrigerated delivery vehicles have extremely limited installation depth between the vehicle chassis and the lift platform. A conventional 200 mm+ cylindrical motor will not fit; the XL22FD at 167 mm overall length clears the constraint while delivering the full 8 N·m torque required to operate a 1000–1500 kg tail lift reliably. Its 24V rating matches the electrical system of most European commercial trucks.
Stationary and semi-portable hydraulic power packs used in steel fabrication shops, automotive service bays, and assembly plants are designed around a specific enclosure volume. The gear oil pump motor in these units must fit within the cabinet alongside the reservoir, valve manifold, and heat exchanger. The short axial length of the XL22FD-24V permits a more compact cabinet design, reducing floor space and shipping costs.
Self-propelled sprayers, seed drills with hydraulic row-unit adjustment, and harvester header lift systems all require compact oil pump motor assembly solutions that can be mounted close to the implement rather than on a centralised PTO-driven pump. The XL22FD-24V's IP54 rating handles spray drift and dust, and its 24V operation works with the electrical architecture of modern precision farming machinery across Australia, Canada, and the UK.
As a hot oil pump motor in centralised lubrication or thermal management loops, the XL22FD-24V drives gear pumps that circulate warm lubricant or dielectric oil at controlled flow rates. Its flat format allows horizontal installation with the shaft pointing downward into the pump, a useful mounting geometry for under-tank installation that keeps the pump flooded and avoids cavitation during start-up.
Dock levellers at distribution centres and boarding bridges at regional airports use hydraulic actuators operated by an electric oil pump motor several times per hour. The cycle — raise, position, hold — lasts a few seconds of motor-on time followed by a long idle period, matching the S2 / 10% ED duty profile of the XL22FD-24V exactly. Its compact format fits into the leveller pit mechanism without conflicting with the drainage slope or the platform hinge hardware.
Ambulance vehicle builders, emergency command unit outfitters, and military vehicle integrators regularly adapt commercial chassis for specialist roles. These conversions often require adding hydraulic actuation for equipment bays, stabiliser legs, or stretcher mechanisms within a vehicle that was not originally designed to accommodate a full-size pump motor. The XL22FD-24V's compact form factor and 24V compatibility with standard vehicle electrical systems make it a common choice for these bespoke integration projects across North America and Europe.
