How to select an AC Motor?
In order to select the appropriate AC Motor for a given application, you need to determine basic specifications. Calculate the required load torque and operating speed. Then you need remember that induction and reversible motors cannot be adjusted; they require a gear head. If this is needed, please select the appropriate gear ratio. Next you should determine frequency, and power supply voltage for the motor.
