Control units for LEM: Perfect communication interfaces for your vehicle.


The intelligent motor controllers from SEG Automotive bring up the new definition in the space of light electric mobility (LEM). Our controllers monitor the load on the motor and accordingly process the matched output which provides a measure of energy efficiency in the drive motor resulted in less heat, NVH and long life.

The embedded electronics and software present in the system take care of dynamic requirements during the vehicle operation for setting up the new standards to establish a developmental collaboration in the field of motion control.


In order to expand the application range of 48V systems and reduce complexity and integration efforts for our customers, SEG Automotive has developed the Vehicle Control Unit (VCU). It is targeting the light electric mobility with a wide application spectrum from 2-wheelers (L1e) to 4-wheelers (L7e) up to industrial and utility applications.
