Many friends, for DC brushless motors and stepper motors is not too well understood, and do not know what the specific differences between the two, Vacuz to give you an introduction, I hope to further understand the DC brushless motors and stepper motors.

Stepper motor is a kind of electric pulse signal into angular displacement or line displacement of the motor. Under normal circumstances, its speed and stop position only depend on the frequency of the pulse signal and the number of pulses, and are not affected by the change of load.

DC brushless motor is a high performance motor without brushes, with permanent magnet rotor, no excitation loss, no heat generating armature winding and mounted on the outer stator for easy heat dissipation.

The difference between DC brushless motor and stepper motor is as follows:

1.Different control precision

According to the different driving principles, DC brushless motors are generally used in places with low control precision, while stepper motors are used in places with high control precision.

2. Different driving principles

DC brushless motors and stepper motors have different driving principles. DC brushless motors are controlled by the AC power provided by Hall element positioning. stepper motors are driven directly by a single pulse voltage, without Hall element positioning, and can be positioned by controlling the number of pulses applied to the motor to determine the rotation angle.

3. Different speeds

DC brushless motors have a higher speed than stepper motors.

DC brushless motors are often used in electric vehicles, household appliances, medical equipment, automobiles, industrial equipment, etc.

The above is the principle and difference between DC brushless motors and stepper motors, mastering these basics will help to better understand the two related content.
