The difference between brushless DC motor and stepper motor
Brushless motor is no brush, life is common electric motor, the old motor is brush, used to change the direction of the current, start fast, starting torque, not easy to bad, maintenance is also easy. The new type is brushless motor, electronic equipment to change the current direction, start smoothly, less torque, bad repair difficult. The above two kinds of motor controller is simple, can only speed, can not locate, that is unable to control the motor rotation angle. Stepper motor can speed, but also positioning, the need for dedicated controller control and power supply, popular to cite an example, through programming, you can make concessions into the motor at 720 degrees per second speed, turn 36 degrees 30 minutes. Of course, the motor accuracy is different. Stepper motor turns fast and torque decreases.
3) based on the principle of the drive is not the same, so the general brushless DC motor for the control accuracy is not high places.Stepper motor is used to control the relatively high precision requirements.
2) brushless DC motor synchronous motor drive principle is different, brushless DC motor is located by Holzer components to provide an alternating power supply to control rotation. Stepper motors are directly driven by individual pulse voltages without the need for Holzer component positioning. The rotation angle can be accurately determined by controlling the number of pulses added to the motor.
What is the difference between brushless DC motor and stepper motor?:1) brushless DC motor is faster than stepper motor.
