How to determine the motor speed ?
Matching motor how to determine the motor speed? The article will explain you how to determine the speed of motor:
Rated speed of the motor selection, according to the requirements of the production machinery and the driving device to consider the ratio of the transmission device.
Revolutions per minute, the motor usually has 3000 1500, 1000, 750 and 600 of the rated speed of asynchronous motor due to slip, to the low speed of 2% ~ 5%.
From the perspective of motor manufacturing, motor with same power if the rated speed is high, the electromagnetic torque size is small, the cost is low and light weight, and high speed motor power factor and efficiency are higher than low speed motor. If the motor can choose higher speed, then the economy is better, but if the resulting motor and the driven machine of the speed difference is too large, the drive series required installed speed reducer is more, it will increase the cost of equipment and energy loss in transmission. Therefore, through the analysis and comparison of selected.
We usually use most of the motor is the use of 4 pole 1500r/min motor, because the rated speed of the motor to adapt to a wide range, and its power factor and work efficiency is also higher.
The above content according to arrangement of the practical problems encountered in the work and, for reference, if there is a problem, please communicate with customer service in the motor.
