EP-XL22QL 2200W 22V Oil Pump Motor
The EP-XL22QL occupies a distinct position in the oil pump motor series: a square-frame, front-mount design that combines the 2200W power class with a uniquely compact square body measuring 120 × 120 mm across the mounting face. Where conventional round-frame motors demand a circular clearance envelope, the QL format’s flat-sided housing integrates cleanly into rectangular equipment bays, bolts flush to machined equipment plates, and stacks alongside other square-section components without wasting installation space in the corners. The result is a highly practical oil pump motor assembly for OEMs building compact, space-efficient hydraulic power units.
Operating at 22V DC with a rated current of 125A and delivering 7 N·m of torque, the XL22QL-24V sits firmly in the mid-range of mobile hydraulic oil pump motor applications — powerful enough for medium-duty lifts and vehicle power units, yet compact enough to fit where larger units cannot.

Five Reasons to Specify the EP-XL22QL
The 120 × 120 mm square mounting footprint of the XL22QL-24V uses installation space in a fundamentally different way from circular-frame motors. Rectangular equipment bays, machined mounting plates, and panel-mount housings all accommodate a square-frame motor with zero wasted corner space. For engineers designing compact oil pump motor set enclosures, this translates directly to a smaller cabinet, lower enclosure fabrication cost, and a cleaner overall layout.
An overall length of just 166 mm places the XL22QL-24V among the most axially compact motors in the 2200W power class. Combined with the square frame, this short length gives system integrators exceptional freedom in arranging the motor within a tight assembly envelope — whether the motor is mounted horizontally in a chassis recess, vertically under a platform floor, or at an angle dictated by an access-constrained installation geometry.
Four corner bolt holes on the front face of the motor allow direct bolting to a pump housing or equipment plate — the same mounting pattern used on many European standard gear pump face mounts. This face-mount arrangement eliminates the need for a separate motor bracket or cradle, saves assembly labour, and ensures precise alignment between the motor shaft centreline and the pump drive bore every time.
A rated torque of 7 N·m at only 125A positions the XL22QL-24V as a genuinely efficient Gleichstrommotor mit hohem Drehmoment for its power class. The combination of reasonable current demand and useful torque output means less heat generation in the supply wiring, smaller contactor ratings, and a battery system that discharges more slowly during lift cycles — all commercially significant factors for fleet operators managing total operating cost.
IP54 sealing protects the motor against dust accumulation on internal components and multi-directional water splashing — the two most common environmental failure modes for motors used on mobile equipment in agricultural, construction, and transport service. Class F winding insulation ensures the motor survives the elevated winding temperatures that occur during cold starts when oil viscosity is at its seasonal peak and pump back-pressure spikes above steady-state values.
How the EP-XL22QL Oil Pump Motor Works
Der Funktionsprinzip des Gleichstrommotors underlying the XL22QL-24V is the same electromagnetic foundation shared by all brushed DC machines: a direct current supplied through terminals A1 and D2 flows into the wound armature, generating a magnetic field that interacts with the fixed field produced by the stator's permanent magnets. The resulting Lorentz force acts tangentially on each armature conductor, and the sum of these forces across the full winding produces the rotational torque that turns the output shaft. This is the core of what people mean when they ask "What is a DC motor and how does it work?" — it is fundamentally a force-on-conductor machine, converting electrical energy directly into mechanical rotation with no intermediate thermodynamic cycle.
What the QL format adds to this basic principle is a mechanically distinct housing geometry. The square outer frame houses a cylindrical barrel of Ø90.5 mm — the barrel contains the stator magnets and armature in the conventional arrangement — but the face plates are extended into a 120 × 120 mm square profile with four corner bolt holes on an 81 mm PCD. This configuration transfers motor mounting loads through the face bolts directly into the attached pump housing or equipment plate, rather than through a clamp bracket around the cylindrical barrel. The result is a stiffer, more vibration-resistant motor-to-pump joint that is particularly valuable when the assembly is subjected to road vibration or the shock loads of repeated heavy hydraulic starts.
The performance curves for the XL22QL-24V show peak efficiency in the 3000–4500 RPM range under mid-range torque loads of 4–6 N·m. Beyond 7 N·m, speed drops progressively and current rises toward the 125A rated value, which is expected and intentional — the S2 / 10% ED rating sets the boundary within which these high-torque operating points are permissible without overheating the Class F winding. The Ø20 mm output shaft with 2-tooth spline delivers this torque to the gear pump with a rigid, backlash-free mechanical engagement that keeps the pump running smoothly across the full speed range.
Materialien und Konstruktion
The square front and rear face plates of the EP-XL22QL are die-cast from high-silicon aluminium alloy — a material choice that combines the thermal conductivity needed for effective heat dissipation from the winding with the structural stiffness required for the face-mount loading condition. In a face-mount motor, the output bearing must carry not just the radial load from the pump's gear mesh force, but also the bending moment induced by the pump weight cantilevered off the motor face. The aluminium alloy casting is thick enough in the bearing boss area to handle this combined loading without deflection that would cause premature bearing or seal wear on the connected pump.
The cylindrical barrel section houses the stator, which carries high-energy neodymium-iron-boron permanent magnet segments bonded to the inner bore surface. NdFeB magnets are specified for their superior energy density relative to ferrite — they generate a stronger magnetic field from a given magnet volume, which allows the motor designer to achieve higher torque output from the compact Ø90.5 mm barrel. The armature core is laminated from cold-rolled silicon steel with controlled silicon content to minimise hysteresis losses across the motor's operating speed range. Armature coils are wound from enamelled copper wire with a thermal index matched to Class F service, slot-insulated with polyester film liners, and finished with a vacuum-pressure impregnation (VPI) varnish treatment to consolidate the winding mechanically and improve heat transfer from the copper to the core.
The commutator is machined from hard-drawn electrolytic copper bars with mica inter-segment insulation. The commutator surface is precision-ground to a mirror finish and run-in with matched carbon brush grades selected for the XL22QL's current density, speed, and expected operating humidity range. Shaft bearings are sealed deep-groove ball bearings with C3 internal clearance, pre-packed with long-life synthetic grease and retained by snap rings to prevent axial displacement under pump-induced thrust loading. All oil pump motor parts are processed and assembled under ISO 9001:2015 certified quality controls.

Where the EP-XL22QL Is Deployed
The square-frame, face-mount design of the XL22QL-24V opens it to a specific set of applications where installation geometry, vibration resistance, and compact packaging converge as the primary selection criteria alongside raw power output.
The square frame's bolt-on mounting face makes the XL22QL-24V a natural fit for tail lift hydraulic power packs where the motor bolts directly to the pump manifold block. On delivery vehicles and refrigerated trucks operating across European transport routes, the 22V operating point and 125A current draw fit neatly within standard 24V vehicle electrical systems — the motor simply sees a slightly lower terminal voltage reflecting battery state of charge during the duty cycle.
Compact scissor-lift work platforms for industrial maintenance tasks require a gear oil pump motor that can be packaged in the frame of a narrow base unit. The XL22QL-24V's 120 × 120 mm face and 166 mm length fit within the chassis sections of slimline platform designs where a round-frame motor of equivalent power would not clear the structural members. Its torque margin above 7 N·m at cold start accommodates the elevated pump back-pressure of viscous hydraulic oil in unheated facilities.
Self-propelled sprayers, planting equipment with hydraulic section control, and harvesting machinery front attachments use compact oil pump motor assembly solutions mounted close to the point of use. The square frame tolerates mounting at any orientation — horizontal, vertical, or inverted — and the IP54 seal handles the chemical spray and airborne dust encountered in crop-protection and soil-preparation operations across Australia, Canada, and the UK farming sectors.
Industrial hydraulic power packs mounted inside switchboard-style enclosures benefit directly from the XL22QL-24V's square format. The motor bolts flush to a panel-machined aperture, the wiring terminals are accessible from the rear, and the overall depth of 166 mm fits within standard 200 mm panel-to-door clearances. This makes it practical to build a self-contained, IP-rated enclosure housing the motor, pump, reservoir, and control relays as a single integrated hydraulic power station.
As a hot oil pump motor driving centralised lube or oil-temperature management loops, the XL22QL-24V maintains controlled oil flow rates through bearing banks, gearbox splash lubrication systems, and hydraulic oil coolers. Its face-mount format allows vertical downward installation directly above a submerged pump inlet, keeping the pump primed at all times and preventing cavitation on start-up when oil is cold and viscous.
Emergency service vehicle builders, military equipment outfitters, and airport ground support equipment manufacturers working in North America and Europe regularly need a compact electric oil pump motor that can be face-mounted directly to a hydraulic manifold in a confined bay. The XL22QL-24V's square form factor and short overall length consistently make it the engineered choice over round-frame alternatives for these bespoke, high-specification integration projects.
