A three in one electric drive unit that integrates motor, reducer and controller into a single housing. Built with a coaxial input and motor shaft design, the EP100 delivers a compact, lightweight solution suited to A0 class vehicles and smaller models where layout space is limited.
A three in one electric drive unit combining motor, reducer and controller in a single housing, built for compact vehicle layouts without giving up power density or efficiency.
The EP100 brings the motor, reducer and controller together in one housing, with the input shaft and motor shaft placed on a common axis. This arrangement removes the need for a spline connection between the two shafts and reduces the number of supporting bearings required, lowering frictional losses in the system.
Built around an oil cooled flat wire motor paired with low slip rate gears and an efficient controller, together delivering an efficiency gain of over 1 percent compared to similar products. An active lubrication design and the removal of the input shaft oil seal further reduce oil agitation losses. At 50.3 kilograms without oil, the EP100 is more than 12 percent lighter than comparable units in its class, and its compact housing keeps the overall footprint suitable for A0 class and smaller vehicle layouts.
Target Applications
The EP100 is suited to A0 class vehicles and smaller models where overall vehicle layout space is limited. Its oil cooled design supports continuous power delivery and efficiency levels that hold up well against competing units, giving vehicle manufacturers a cost effective option for compact platforms without compromising on performance. The unit’s low weight and reduced axial footprint make it a practical fit for tightly packaged front axle installations.

What makes our EP100 different
Compact design
Motor, reducer and controller share a common housing, with the input shaft and motor shaft placed on one axis. At 50.3 kilograms, the unit is the lightest in its class, over 12 percent lighter than comparable products.
High efficiency design
An active lubrication approach combines an oil cooled flat wire motor with low slip rate gears and an efficient controller, raising efficiency by more than 1 percent over similar products while lowering frictional resistance.
NVH performance
Fine, tall teeth and gears with a high contact ratio give the EP100 strong noise, vibration and harshness performance.
