Wiring a multi-speed motor from a tower fan
The Shanhu SHM-40 motor is a three speed 230V motor. It has 7 wires to connect.

This is how I connected the motor after my controller board had a broken power supply for the remote control.


Brown: Brown wire of your power cord.
Grey: Connect to Blue, Yellow or Red to choose your speed. Ideally, with a 2A fuse.
White: Connect to the capacitor.
Blue: Slow Speed
Yellow: Medium Speed
Red: Max Speed
Black: Blue wire of your power cord and the capacitor.
