Brushless dc motor controller and step motor controller

brushless dc motor controller is a kind of high performance motor controller, its the biggest characteristic is the external characteristic of dc motor controller without mechanical contact of brush structure, it USES the permanent magnet rotor, no excitation loss, fever and installed on the outside of the stator, armature winding heat easily. Stepping motor controller is the electrical pulse signal into angular displacement or linear displacement of open loop control yuan stepper motor control device. In the case of the overload, the speed of the motor controller, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change. Here today and share about the main difference between the two? Help people better understand the difference between two: 1. Brushless dc motor controller is higher than the speed of the stepper motor controller. 2. Brushless dc motor controller, and the general principle of stepping motor controller is different, brushless dc motor controller is provided by hall element positioning alternating power control. Stepping motor controller is driven by single pulse voltage directly, don't need a hall element, can be added to the motor by controlling the number of pulse controller to precise positioning rotation Angle; 3. Based on driving principle is different, so the general brushless dc motor controller is used to control the accuracy is not high, the stepping motor controller is used to control the accuracy is higher.
