Single-phase (household electricity): 220V, 50HZ
Three phase (industrial electricity): 380V, 50HZ
Voltage may vary from country to country; e.g. single-phase 110V, 60HZ; three-phase 415V,60HZ
Number of poles: 2, 4, 6, 8 (poles are magnetic poles, N/S, a few pairs are a few poles)
The speed of the motor varies according to the number of poles: 2-stage speed 3000r/min, 4-stage speed 1500r/min, 6-stage speed 1000r/min
So the speed of the machine is determined by the motor speed and the wheel diameter
Motor speed*motor wheel diameter=machine speed*main wheel diameter
Pellet mill with 4-pole motor.
Generally, the three-phase motors we use are 4-pole motors or 6-pole motors.
Common motors used in our machines.
2.2kw/3kw motor: 220V, 50HZ, single phase, 2 poles
5.5kw or more: 380V, 50HZ, 3-phase, 4/6 poles
