EP-XL40LT 4200W 24V Oil Pump Motor
The EP-XL40LT represents the high-power tier of the oil pump motor series — a 4200W, 24V hydraulic oil pump motor engineered for heavy-duty mobile and industrial applications where lower-power units simply cannot sustain the hydraulic flow rates and circuit pressures required. With a rated torque of 14 N·m, this motor generates nearly double the torque of the 2200W variants in the XL22 family, making it the specified choice for heavy tail lifts, large-platform aerial work equipment, industrial dock levellers handling multi-tonne loads, and specialised vehicle power units driving multiple hydraulic functions simultaneously.
Operating at 24V with a rated current of 210A, the XL40LT-24V is designed from the ground up to manage the thermal and electrical stresses of high-power intermittent duty. The duty rating of 13 min–28% ED reflects a step change from the lighter-duty XL22 series: longer permissible on-times and a higher energisation duty allow the motor to sustain the sustained pumping cycles needed when filling large-volume hydraulic cylinders or operating multi-actuator circuits. Class F winding insulation and the robust finned aluminium housing work together to manage heat buildup during these extended on-periods. Optional 48V configuration is available for applications requiring lower supply current at equivalent power output.

Five Reasons the EP-XL40LT Is Chosen for Heavy-Duty Hydraulics
At 4200W, the XL40LT-24V sits in a power band that very few compact DC motors in the oil pump motor class can reach while maintaining a manageable physical envelope. This power level sustains the high hydraulic flow rates needed to extend large-bore cylinders quickly, operate multi-valve circuits, or drive gear pumps at elevated back-pressure without stalling or overheating during the longer on-times these applications demand.
A 14 N·m rated torque output makes this the highest-torque motor in the XL series covered here — twice the torque of the XL22 family's 7–8 N·m range. For system designers working on heavy dock levellers, large tail lifts rated above 2000 kg, or industrial crane stabiliser circuits, this torque headroom means the motor handles peak load demands at start-up without approaching its thermal or current limits, extending both the motor's service life and the reliability of the hydraulic circuit it drives.
The 13 min–28% ED duty cycle is a substantial step up from the 10% ED ratings of the lighter XL22 series. In practice, 28% ED means the motor can sustain nearly a third of a reference cycle time at full load — well suited to applications where pump-on time per cycle extends to 20–30 seconds, such as filling large hydraulic cylinders on crane outrigger legs, stabiliser pads, or multi-stage lifting platforms. This rating eliminates the need for oversizing and leaves meaningful thermal headroom for occasional duty exceedances.
The XL40LT-24V features a ribbed/finned outer housing visible in the product photograph — a significant departure from the smooth barrel of the XL22 series. These fins increase the effective surface area of the aluminium housing, improving passive convective heat dissipation during the motor's on-time. Combined with Class F winding insulation, the finned design keeps winding temperatures within safe limits during the extended 28% ED duty cycles without requiring active forced-air cooling.
The XL40LT-24V is supplied with a rigid mounting bracket visible in the outline drawing — a foot-mount configuration that attaches to the motor body and provides two bolt-down points for fixing the assembly to a baseplate, chassis rail, or power pack sub-frame. This makes installation in open-frame power pack enclosures straightforward, with the pump hanging off the motor's 9-tooth gear output and the motor secured by its foot bracket independently of the pump housing loads.
How the EP-XL40LT Operates — DC Motor Working Principle at High Power
The dc motor working principle of the XL40LT-24V follows the same electromagnetic fundamentals as the rest of the brushed permanent magnet DC family: applying voltage across terminals A1 and D2 drives current through the wound armature, generating a magnetic field that interacts with the permanent magnet stator field to produce a tangential force on each armature conductor. The sum of these Lorentz forces across the complete winding produces the shaft torque. What changes at 4200W and 210A is the scale of everything: heavier-gauge armature conductors to carry the elevated current, more powerful permanent magnet stator segments to sustain the higher flux density required for 14 N·m, and a larger commutator with more segments to handle the increased commutation energy without excessive arcing or brush wear.
The finned housing of the XL40LT-24V is a direct engineering response to the thermal challenge of high-power intermittent operation. At 4200W input, even at 85% efficiency, the motor dissipates approximately 630W as heat during its on-time. In a smooth-barrel housing, this heat would accumulate in the winding far faster than it could conduct to the surrounding air. The external fins increase the housing's effective surface area by a factor of three to four, dramatically accelerating convective heat transfer to the ambient air and keeping steady-state winding temperatures within the Class F 155 °C limit even at 28% ED. This is why the XL40LT does not carry an IP rating — the open, finned housing trades ingress protection for superior thermal performance, a design trade-off appropriate for the sheltered installation locations typical of power pack enclosures and vehicle chassis bays.
The performance curves for the XL40LT-24V show the characteristic shape of a permanent magnet DC motor: speed falls linearly as torque increases, while current rises proportionally. Peak efficiency sits in the 3500–5000 RPM band under mid-range loads of 8–10 N·m. At the rated 14 N·m, speed is lower and current approaches 210A — the thermal design of the motor is validated at this operating point under 28% ED conditions. Engineers integrating this motor as the prime mover in a gear oil pump with motor assembly should size the gear pump's displacement to match the motor's rated speed range, ensuring maximum hydraulic efficiency aligns with the motor's peak electrical efficiency window.
Materials & Heavy-Duty Construction
The outer housing and end shields of the EP-XL40LT are cast from high-silicon aluminium alloy, then CNC-machined to achieve the dimensional accuracy needed for precise shaft alignment and bearing preload. Unlike the lighter XL22 variants, the XL40LT housing includes integral cooling fins cast as part of the housing blank — these fins are not added-on accessories but a structural feature of the casting, ensuring they conduct heat efficiently from the core to the outer surface. The foot-mount bracket is machined from mild steel plate and bolted to the motor body with interference-fit fasteners to prevent fretting between motor and bracket under the vibration loads of vehicle-mounted or machine-mounted service.
The armature is wound with heavier-gauge enamelled copper wire than the XL22 series, selected to carry the 210A rated current with acceptable resistive losses and a voltage drop that keeps the effective terminal voltage at the commutator within the design window. The armature core uses cold-rolled silicon steel laminations of controlled thickness, stacked to minimise eddy-current losses at the motor's operating speed range. Coil ends are formed and braced to resist movement under the centrifugal forces and vibration that arise in high-power, high-speed operation — loose coil end-turns are a common failure mode in high-current motors, and the end-turn lacing and impregnation varnish treatment on the XL40LT prevents this.
The commutator is manufactured from premium-grade electrolytic copper bar segments with mica inter-segment insulation, ground and run-in to a surface finish that minimises the contact resistance variation that causes current imbalance between brush tracks. Two sets of brushes are arranged at 180° to balance the armature current symmetrically, reducing brush wear and the electromagnetic torque ripple that causes vibration in the connected pump. All oil pump motor parts in the XL40LT are produced and assembled under ISO 9001:2015 quality management system controls, with each finished motor subjected to a no-load run-in test and electrical parameter verification before shipment.

Application Scenarios
The 4200W output and 14 N·m torque of the EP-XL40LT target the heavy end of the mobile and industrial hydraulic spectrum. Below are the primary sectors where this motor is specified — applications where a 2200W unit would either stall under load or require an unacceptably long cycle time to complete the required hydraulic movement.
Tail lifts rated for freight above 2000 kg — common on long-haul flat-bed trucks, heavy-duty refrigerated semi-trailers, and large vans — require a high torque electric motor capable of building hydraulic pressure quickly against a substantial static load. The XL40LT-24V's 14 N·m output and 210A current capacity meet this demand with torque headroom to spare, ensuring smooth, fast lift cycles even when the platform starts with a full pallet load.
Aerial work platforms with platform heights above 15 m use larger hydraulic cylinders with greater bore areas, requiring proportionally more pump flow rate to achieve acceptable extension speeds. The XL40LT-24V drives the gear pump at the speeds needed to fill these cylinders within the operator's expected cycle time, making it the standard choice for electric oil pump motor specification in medium-to-large boom lift and scissor lift designs across Europe and North America.
Fishing vessels, workboats, and coastal freighters use hydraulic winches, crane derricks, and hatch covers driven by compact hydraulic power units. In vessels with 24V DC ship service power — particularly smaller commercial craft — the XL40LT-24V provides the sustained 4200W output needed for deck hydraulics without requiring an AC generator and inverter system, keeping the electrical architecture simple and reducing maintenance exposure at sea.
Open-frame hydraulic power packs in press shops, stamping lines, and material-handling systems use foot-mounted motors bolted directly to a rigid steel base, with the pump cantilevered off the motor's output shaft. The XL40LT-24V's integral foot-mount bracket and Ø119 mm output flange are purpose-designed for this configuration, and its 28% ED rating accommodates the sustained pump-on periods required during press-stroke cycles and clamp operations in manufacturing environments in Germany, the UK, and across North America.
Self-propelled forage harvesters, large round-baler ejectors, and heavy front loader assemblies on articulated tractors use hydraulic circuits that demand both high flow rate and sustained operation — not the brief, intermittent bursts of a tail lift, but extended periods of continuous lifting or clamping force. The XL40LT-24V's 28% ED rating and finned passive cooling make it one of the few compact DC pump motors suited to these sustained agricultural duty profiles across Australian, Canadian, and European farming operations.
Heavy roadside recovery vehicles, truck-mounted crane units, and mobile workshop platforms use hydraulic outrigger legs, crane booms, and rotary drives powered by onboard 24V battery systems. The XL40LT-24V handles the simultaneous demands of these multi-actuator circuits — where the pump may need to supply several cylinders in sequence during a recovery or lift operation — making it a reliable oil pump motor set choice for recovery equipment builders in Australia, Canada, and the UK.
