A stepper motor is a brushless electric motor that evenly divides it’s rotation into a number of equal steps. The motor’s position can then be controlled and held at one of these steps without other position sensing as long as the motor is properly regulated to the torque and speed of the system and applications.
How do you drive a stepping motor?
A stepper motor can be bipolar or unipolar, and a charge needs to be driven through the coiled wires, at both high or low levels. This will make the stepper rotate, driving the motor. The mechanism is more complex than a simple brushed motor. Stepper motors require a stepper controller to make the motors run
How to calculate step angle in stepper motor?
To calculate the step angle of a stepper motor, just divide 360 degrees by the number of steps a motor takes to complete one full revolution of the motor itself. This can differ whether the motor is set to half or full mode, and the number of steps it takes to complete one revolution (either doubled or halved).
