Brushless DC Electric Motor (with Hall Sensor)

intro.png

This DC electric motor project uses a Hall sensor to detect the position of the rotor and turn on the electromagnet in the precise moment.

Sensor: UGN-3503-U hall sensor

IC1: LM358N (dual OP amp)

IC2: CD4001 (quad NOR gate )

FET1: IRFD120 (N-channel power mosfet)

This circuit is the same I used in my previous post "magnetic pendulum" . For additional details, refer to post.

IMPORTANT:

1) electromagnet north pole UP

2) rotor north poles OUT

3) hall sensor branded side UP
