stepper motors factory teaches you how to choose stepping motor

The torque of stepping motor is selected to maintain the torque of stepping motor, which is similar to the "power" called by traditional Motors. There are, of course, essential differences. The physical structure of the stepping motor is completely different from that of AC and DC motors. The output power of the motor is variable. Which type of motor is usually selected based on the required torque(ie, the torque of the object to be driven). Roughly speaking, the torque is below 0.8 N.m, select 20, 28, 35, 39, 42(the fuselage diameter or square of the motor, in mm); If the torque is about 1 N.m, the 57 motor is more suitable. In the case of several N.m or greater torque, step motors with specifications such as 86, 110, and 130 are selected.

The free starting frequency of stepper motor is usually referred to as "empty starting frequency". This is an important indicator for purchasing Motors. If it is required to start and stop frequently in an instant, and the speed is about 1000 RPM(or higher), it is usually necessary to "accelerate the start." If you need to start directly to achieve high-speed operation, it is best to choose a reactive or permanent magnet motor. The "empty frequency" of these Motors is relatively high.
