Selecting by Spindle

Round motors are generally used as spindle motors due to the need for high-rotation precision, a high-accurate shaft perpendicularity, low noise and long life. Motor output is basically proportional to the voltage used and the motor size, so selecting the largest size allowable is best for power consumption and the life of the machine. Please select the motor size, rated voltage, shape of input terminals and shaft dimensions best suited for your needs.
