Design and Manufacturing

The Rotontek High-Performance Electric Transaxle is a product of extensive research, design iterations, and manufacturing excellence. The transaxle architecture integrates the electric motor, transmission, and differential into one compact unit, which significantly reduces the complexity and weight.

Electric Transaxle

Motor Design

The motor is an Axial-Flux Permanent Magnet Synchronous Motor (AFPMSM), a unique design that offers superior performance and efficiency over the conventional radial-flux motors. This design allows for higher torque output at lower RPMs, thus making it an ideal choice for high-speed vehicles.

Transmission System

The transmission system incorporates a single-speed gearbox with an optimized gear ratio to provide an ideal balance between acceleration and top speed. The gears are manufactured from high-strength, heat-treated alloy steel to withstand high torque loads.


The differential system is a limited-slip type, designed to provide maximum traction and control. It features an electronically controlled, hydraulic actuation system that adjusts the torque distribution based on the vehicle's speed and driving conditions.
