Motor according to the layout of the classification should be divided into horizontal and vertical motor. Because of the characteristics of the water pump is small relative to the starting torque, start frequency is relatively small, continuous operation time is relatively long and so on characteristics, therefore the majority of water pump motor of squirrel cage rotor asynchronous motor or synchronous motor.
Pump motor
The choice of pump motor according to the shaft power choice, motor power is greater than the shaft power of a class; for example: the shaft power is 15KW, the choice of the motor should be: 18.5KW as for the use of a few pole motor, according to the requirements of the practical conditions. 2 pole motor is generally used in the head slightly high, flow is not the case (accounting is more complex). 4 pole motor for occasions with large discharge head and small flow. Ultra large flow, the lower head to choose 4 or 6 pole motor, when the choice of six pole motor, the power can be reduced by a grade according to the shaft power.
