motor 2 pole vs 4 pole

ThePanda. As the name implies, a 2-pole motor has 2 electromagnets; 1 north and 1 south. A 4-pole motor has 4 eletromagnets; 2 north and 2 south. On a 4-pole motor, the magnets are set up in a north-south-north-south configuration. Basically, a 2-pole motor is a good RPM motor while a 4-pole motor, having more magnets, will have more torque. roma 4 1 5
