What's the difference between a step motor and a brushless motor?
Brushless motor is no brush, the common life is the electric motor, the old motor has brush, used to change the direction of current, start fast startup torque, not bad, maintenance is easy. The new ones are brushless motors, changing the direction of the current in electronic devices, starting the stable, the torque is smaller, and the maintenance is difficult. The above two kinds of motor controller are simple to adjust speed, cannot locate, namely cannot control electromotor rotation Angle. Speed stepper motors will also be able to locate, need special control and power supply, popular as an example, through programming can be concessions into the speed of the motor according to 720 degrees per second, around 36 degrees 30 minutes. Of course, you can't have a different precision. The speed of the stepping motor is reduced.
The consistent place for stepping motor and brushless motor is the need to move through the electrical pulse. But brushless motor without stepper motor design theory so only to a certain extent, the same properties, many ways to do less than precise control of stepping motor.
The step motor can control the Angle of rotation precisely, but no brushless motor is not allowed The motor rotor is a grass-fed structure, neither winding nor permanent magnet. On the rotor of the brushless motor is the rotary rectifier and the excitation winding Brushless motor is used to generate power and power. Step motors are used for precise positioning, such as tool displacement control on machine tools
