Moteur de pompe à huile EP-XL16LTBX 1600 W 12 V
The EP-XL16LTBX is a high-performance oil pump motor engineered for demanding mobile and industrial applications. Operating at a nominal voltage of 12V DC and delivering a continuous output of 1600W, this electric oil pump motor is built to drive hydraulic and lubricating oil circuits in vehicle power units, aerial work platforms, boarding bridges, and specialised lifting equipment. As a direct-current permanent magnet motor, it combines a compact body with high starting torque — reaching a rated torque of 6 N·m — ensuring reliable and immediate response even under heavy load starts.
Designed with an IP54 ingress protection rating and Class F insulation, the EP-XL16LTBX withstands the vibration, moisture, and temperature fluctuations found in real-world operating environments. Its 9-tooth gear interface and clockwise (CW) rotation allow precise coupling with standard hydraulic gear pump assemblies. Optional voltage configurations of 24V and 48V are available, giving system integrators flexibility without redesigning the mechanical interface. =

Cinq avantages clés du produit
Delivering 1600W from a compact, lightweight housing, this gear oil pump motor achieves an excellent power-to-size ratio. The permanent magnet DC design maximises magnetic flux without the bulk of field windings, making it the ideal choice where installation space is constrained.
An IP54 protection rating seals this hydraulic oil pump motor against dust ingress and water splashes from any direction. Combined with Class F insulation (rated up to 155 °C), it maintains performance stability across outdoor and semi-enclosed mobile machinery environments.
While the standard model runs on 12V, configurable options for 24V and 48V are available on request. This makes the motor compatible with a wide spectrum of vehicle electrical architectures — from compact 12V material-handling equipment to 48V industrial systems — without mechanical redesign.
The 9-tooth gear output and clockwise shaft rotation are purpose-designed to mate with industry-standard gear oil pump with motor assemblies. This factory-matched interface eliminates the need for adapter couplings, shortening assembly time and reducing potential leak points in the hydraulic circuit.
Rated at S2 min–9% ED (intermittent duty), the motor is thermally engineered for the cyclic start-stop profiles of lifts, loading ramps, and emergency pump circuits. Its thermal margin under intermittent operation is generous, making unexpected duty spikes manageable without tripping thermal protection.
How This DC Oil Pump Motor Works
At its core, the EP-XL16LTBX is a moteur à courant continu à aimant permanent. When 12V DC is applied across the motor terminals (A1 to D2 as shown on the wiring diagram), current flows through the wound armature. The interaction between the armature's electromagnetic field and the field generated by the permanently magnetised stator creates a tangential force on the rotor conductors, producing rotational torque — this is the foundational Principe de fonctionnement d'un moteur à courant continu that governs all brush-type DC machines.
Because the stator flux is fixed (permanent magnets require no excitation current), the motor delivers high torque immediately on start-up without the lag associated with separately-excited or series-wound machines. Speed is primarily governed by back-EMF: as rotor speed increases, the back-electromotive force rises and limits current draw, naturally stabilising the operating point at a given load. This self-regulating behaviour means the motor works reliably across a range of hydraulic load conditions without requiring closed-loop electronic feedback in simple on/off pump circuits.
The 9-tooth gear output on the drive shaft couples directly to the inlet gear of a hydraulic gear pump. As the motor turns, the pump draws fluid from a reservoir and delivers it at pressure to the hydraulic circuit — whether that is a scissor-lift cylinder, a dock leveller ram, or a vehicle stabiliser leg. The S2 / 9% ED duty rating reflects that most such pump circuits operate in short bursts, allowing the motor's thermal mass to absorb heat during operation and dissipate it during the off period, keeping winding temperatures within the Class F limit.
Qualité des matériaux et de la construction
The housings and end shields of the EP-XL16LTBX are precision-machined from cast aluminium alloy, balancing structural rigidity with low overall weight — a critical factor in mobile equipment where every kilogram affects payload capacity. The aluminium surface is treated with a conversion coating to resist corrosion even in the misting environments encountered around hydraulic power packs.
The armature core is laminated from high-grade cold-rolled silicon steel punched to tight dimensional tolerances. Lamination minimises eddy-current losses and keeps the motor running cool during the repeated start cycles typical of lift and ramp applications. The commutator segments are made from electrolytic copper for low contact resistance and prolonged brush-life under the high current demands — up to 190A — of this moteur à courant continu à couple élevé.
Carbon brushes are selected for their low friction coefficient and self-lubricating properties. Brush holders maintain consistent spring pressure across the commutator surface to prevent arcing and voltage spikes. Output shaft bearings are deep-groove ball bearings with sealed grease packs rated for extended maintenance-free intervals, and the shaft itself is manufactured from precision-ground alloy steel to handle both the radial loads imposed by the gear pump coupling and the thrust loads generated during start-up transients. Every major component meets ISO 9001:2015 process controls from incoming inspection through final run-in testing.
Scénarios d'application
The EP-XL16LTBX oil pump motor covers a broad range of mobile and stationary hydraulic power applications. Its compact form factor, high starting torque, and weather-resistant construction make it particularly well-suited for the following sectors:
Used as the prime mover in truck-mounted hydraulic power packs, tipper-body systems, and tail-lift units, this electric oil pump motor delivers the immediate torque necessary to pressurize circuits quickly, reducing cycle time on loading docks.
The motor powers the hydraulic pump driving scissor-lift cylinders in material handling and maintenance platforms. Its IP54 rating and intermittent-duty optimisation match the typical lift-and-lower cycle of aerial work equipment used in warehouses and construction sites.
Ground support equipment including boarding ramps, luggage carts, and push-back tractors rely on compact moteurs électriques à courant continu for reliable, battery-powered hydraulic actuation. The XL16LTBX-12V is a well-proven fit for such applications.
As a transformer oil pump motor, the EP-XL16LTBX drives circulating pumps that move dielectric oil through transformer cooling loops. Its sealed construction and stable low-speed performance make it compatible with continuous low-load circulation duties in electrical substations.
Centralised lube systems for gear-driven machinery, press tooling, and CNC machining centres use a hot oil pump motor to maintain oil viscosity and delivery pressure. The motor's tolerance for intermittent bursts aligns with the demand cycles of automated lubrication controllers.
Ambulance stretcher lift mechanisms, hospital bed adjusters, and emergency rescue spreaders require a petit moteur à courant continu that responds instantly and operates quietly on battery power. The XL16LTBX-12V meets these requirements while fitting within tight enclosure dimensions.
