The disadvantages of brushed motors are eliminated. Brushless motor The brushless motor adopts electronic commutation, the coil does not move, and the magnetic pole rotates. Repel each other, generate power, and push the motor to rotate. Brushless coreless motors have no iron core in the rotor, and brushless coreless motors have no iron core in the stator.

The controller of the brushless motor can also realize some functions that cannot be realized by the brush motor, such as adjusting the power switching angle, braking the motor, making the motor reverse, locking the motor, and using the brake signal to stop the power supply to the motor.. To To To Second, the difference between brushed and brushless To 1. When the motor is working, the coil and commutator rotate, but the magnetic steel and carbon brush do not rotate.

Classification of coreless motors Coreless motors are divided into two types: brushed and brushless.1. The electronic alarm lock of the battery car now makes full use of these functions. The carbon brushes need to be replaced regularly; the on and off alternately between the carbon brushes and the coil terminals will cause electric sparks, electromagnetic damage, and interference with electronic equipment.

The brushless DC motor is composed of a motor body and a driver, and is a typical mechatronic product. The carbon electrode slides on the coil terminal, like a brush on the surface of the object, so it is called carbon 'brush'.
