Is the stepper motor DC or AC Is the stepper motor a brushless motor?
Is the stepper motor a brushless motors? Stepper motor is a special motor, which is a brushless motor.
Stepper motor is an actuator that converts electrical impulses into angular displacement, and the rotation angle and speed of stepper motors can be controlled by controlling the number and frequency of pulses.

Since stepper motors do not require brushes when rotating, they are called brushless motors.
Stepper motor is a kind of AC motor, which is an actuator that converts electrical impulses into angular displacement.

It has several magnetic poles on the stator, and torque is generated by the action of the magnetic poles. There is a certain magnetic material on the rotor, and the magnetic pole of the stator generates a magnetic field, which interacts with the magnetic material on the rotor, so that the rotor rotates.

The classification of stepper motors can be classified according to factors such as their structure, size, use, etc. According to the structure, it can be divided into three types: reactive type, permanent magnet type, and hybrid type. According to the size, it can be divided into four types: micro, small, medium, and large. According to the application, it can be divided into four types: standard type, high-speed type, low-speed type, and linear type.
The advantages of stepper motors are as follows:
High precision: Since the stepper motor controls the rotation angle and speed by controlling the number and frequency of pulses, the accuracy is higher than that of ordinary motors.
High reliability: Since the stepper motor is a brushless motor and has no easily damaged parts such as brushes and commutators, the reliability is higher than that of ordinary motors.

Low noise: Since the working principle of stepper motor relies on the interaction of magnetic fields, the noise is lower than that of ordinary motors.
Wide speed regulation range: Since the stepper motor can adjust the rotation speed and angle by controlling the number and frequency of pulses, the speed regulation range is wider than that of ordinary motors.

Brushed motor vs stepper motor, difference between stepper motor and brushless dc motor
Both brushed motors and stepper motors are motors, and there are certain differences between them:
1. The brushed motor is to change the direction of current through the carbon brush and commutator, so as to realize the rotation of the motor. The rotor of a brushed motor is composed of a coil and magnetic steel, and the stator is composed of silicon steel sheets.

2. Stepper motor is an actuator that converts electrical impulses into angular displacement, and the rotation angle and speed of the stepper motor can be controlled by controlling the number and frequency of pulses.
3. In terms of structure, the rotor and stator of the brushed motor are rotating, while the rotor of the stepper motor is stationary, and only the stator rotates.
4. In terms of working principle, the brushed motor relies on carbon brushes and commutators to change the direction of current, while the stepper motor controls the rotation angle and speed by controlling the number and frequency of pulses.
5. In terms of performance, the speed range of brushed motors is wider, but the torque is small, while the speed of stepper motors is lower, but the torque is larger.

6. In terms of use, brushed motors need to replace carbon brushes and commutators regularly, while stepper motors do not need maintenance.
In short, there are obvious differences in the structure and working principle of brushed motors and stepper motors, and it is necessary to choose the appropriate motor according to actual needs.
