WebJul 6, 2024 · If the rotor was turning at a speed of 2975 rpm, the slip frequency would be 25 cpm. Similarly, with a 4-pole motor, the magnetic field rotates at exactly half of AC line frequency or 1500 cpm. Therefore, if a 4-pole motor was actually running at 1480 rpm, the slip frequency would be 20 cpm. WebThe 2028-1700Kv motor is available to those that are ready to take their extreme speed setups to the next level. With the success of the 1721-2400kv we went even bigger. With a larger diameter and length, it handles more power/wattage. This allows more torque and speed potential. It will just need to be geared differently as the kv is lower.Ideal for …
