Summary of water pump motor speed:
The water pump is mainly composed of a pump casing, an impeller, a pump cover, a mechanical seal, a pump shaft, a bearing, a bearing box, a motor, and a base. The most commonly used driving method of a water pump is a motor drive. The commonly used motor type is a three-phase asynchronous motor. The speed of a three-phase asynchronous motor is graded and is determined by the "number of poles" of the motor.
The "number of poles" of a three-phase asynchronous motor is the number of magnetic poles in the designated sub-field. The stator windings are connected in different ways, which can form different numbers of poles of the stator magnetic field. The number of poles of the selected motor is determined by the speed required by the load. The number of poles of the motor directly affects the speed of the motor. The current of the motor is only related to the voltage and power of the motor.
Motor speed=60x motor frequency/motor pole pair number
