motor that control the treadmill functions.

READMILL MOTOR

This is a variable speed for DC motor. To control the 0 –180(230VAC) or 0-90(120VAC) voltages on the main controller, it can to increase or

decrease speed of running belt.

ENERAL INFORMATION

ONSOLE

Contains Key controls and LCD Display.

Main controller Include power supply 、 motor driver control circuit and incline control circuit.

Have three wires red, black and green.

If there is DC voltage on the Red (white) wire (M+) the treadmill motor will turn clockwise.

If there is DC voltage on the Black wire (M-) the treadmill motor will turn counter-clockwise.

The higher the voltage the faster the motor turns

The green wire is ground.
