NettetWhat has changed is the types of motors used for the application and types of motor controllers that are available. The most widely used motor type for a direct drive application is typically a high pole count permanent magnet synchronous motor, (A.K.A. Brushless DC), that has a large diameter and short axial length. NettetA motor's top speed (RPM) is determined by several things but one that is useful to be able to discover is the number of poles. Normally we don't need to worry about …

Nettet30. mai 2024 · The number of rotor poles must always match the number of stator poles. For most other types of motors, the rotor is constructed so that the number of rotor poles matches the number of stator poles. In induction motors, the slip at the rated frequency and load is between about 1.5% and 3% of synchronous speed for "standard" motors.
