The system is mainly composed of counterweight and weight compensation device.

6. Electric drive system

The function of electric drive system is to provide power and realize elevator speed control. The electric drive system consists of traction motor, power supply system, speed feedback device and motor speed regulating device.

7. Electrical control system

The main function of the electric control system is to manipulate and control the operation of the elevator. The electrical control system is mainly composed of control device, position display device, control panel (cabinet), leveling device and layer selector.
