Calculate Number Of Motor Poles
To calculate the number of motor poles we need the motors max Hz and RPM. The formula is (120 * Max Hz) / Max RPM.
The formula is: (120 * Max Hz) / Max RPM.
For example:
Motor Max Hz = 300
Motor Max RPM = 17400
Example: (120 * 300) / 17400 = 2.068 when rounded is 2 Poles
Quick Tip: If the motor rotates 24,000 RPM at 400 Hz, it is a 2 pole motor!
