Main unit

Main control unit and power electronics for wheelchairs

At the main unit, the signals from the joystick and the control panel are received via CAN-Bus and transformed into correspondant commands for the particular motors.

A control loop is checking the power consumption and the temperature of the electric drive unit, and prevents thereby damage through overcharge.
The motor end stage is checked at every start-up of the wheelchair, to ensure the right function of the control unit and the installation of the drive motors.
