Tips: Operating characteristics of stepper motor

The Nema 34 stepper motor is an open-loop hybrid control motor that converts the electrical pulse signal into an angular displacement or linear displacement from a functional point of view.

In the case of non-overload, the bipolar stepper motor's speed and stop position only depend on the frequency and pulse number of the pulse signal, and will not be affected by load changes like many other motors. When running, the stepper driver receives a pulse signal, and then drives the motor to rotate a fixed angle in the set direction.

The rotation angle of the stepper motor is the step angle mentioned in the parameter, and its rotation is run step by step at a fixed angle. Because of this operating mode, the motor can control the angular displacement by controlling the number of pulses, so as to achieve the purpose of accurate positioning.

Stepper motor can also control the speed and acceleration of the motor rotation by controlling the pulse frequency, and use this method to adjust the speed of the motor. The motor cannot directly achieve high-speed operation, it needs an acceleration process, and it takes a certain amount of time to reach a higher operating speed.
