QEXPAND motor speed controllers are specifically designed for low-voltage electric motor drives, with high-performance FOC algorithm, flexible I/O definition, friendly configurable, CAN communication and safety protection. Based on over million units of QEPXAND controllers delivery in last decade, the performance, stability and reliability of our controllers have verified and recognized by the market.

The catalog covers 24VDC to 96VDC battery driven vehicles with AC induction motor, DC motor, PMSM motor and EPS motor implemented.

With rich engineering experience, we can also provide the customers with effective and efficient technical support services.

Besides of the factory in China, production and assembly facility in Korea is also being constructed to ensure the supply chain safety.
