Types

Electric motors can be divided into 3 main types: alternating current (AC) motors, direct current (DC) motors, and universal motors. An AC electric motor will not run when supplied with DC current, and a DC motor will not run on AC current; a universal motor will however run on either AC or DC current.

Subtypes:

• AC electric motors:
• DC electric motors: Brushed DC electric motor, Brushless DC electric motor
• Universal motors:
