Changing Stepper Motor Rotation Direction

Stepper motors are motors whose speed, direction of rotation and position are always known. As the name suggests, these engines move in certain steps. But it is up to you to determine these steps. The direction of rotation can be changed by changing the order of the applied pulses. But how? In this week's blog post, we will explain this subject to you in a way that has never been explained before.

Stepper Motor Rotation Direction

As the number of steps made by stepper motors per revolution increases, their sensitivity increases in direct proportion to this. Increasing precision in a cycle also means increasing cost. The direction of rotation of the motor is related to the direction of the voltages applied to the phases. In these step-by-step motors, only one step movement is achieved by energizing one of the windings. The degree of steps is related to the design of the engine. Relays are used to change the rotation direction of these motors. Changing the direction of any phase means changing the direction of the rotating magnetic field. You have 2 options to change the direction of rotation of the engine. One of these options is to change the location of the auxiliary winding ends, and the other is to change the place of the main winding ends. During this process, the current of the field winding is changed. Thus, the motor starts to rotate in the direction you want.

However, the point to be considered here is that if both current directions are changed, the direction of the motor will not change. To change the direction of rotation of the motor, the end of any of the windings must be changed. We have come to the end of our blog post explaining how to control the direction of rotation of the stepper motor. This process can be done more easily with the help of a driver.
