What are the differences between the advantages and disadvantages of a brush motor and a brushless motor? How the stator and rotor are winding?

When it comes to motors, we often mention brush motors and brushless motors, many of the same product, such as pumps, power tools, electrical appliances, etc., there is a difference between brush and brushless, so there will be some comparisons, more than price, more than performance, more than quality, etc., and how to wind the coil, wrap the stator or rotor, these are some common knowledge issues. Here Vacuz give you an introduction to it! Hope it can help everyone!

Brush motor and brushless motor difference:

Brush motor structure is relatively simple, control is also relatively easy, the price is also more affordable, but are configured to commutation brushes, using mechanical commutation, with the work of continuous wear and tear, it will affect the life of the motor, the failure rate is relatively high, to a certain time will need to replace the carbon brushes, and then some of the higher requirements of the site can not be used, will produce electric sparks, easy to accidents.

Brushless motors use electronic commutation, instead of mechanical commutation, longer service life, less failure, basically free from maintenance, the work process will not produce sparks, high safety, suitable for many high precision places, the disadvantage is that the control circuit is more complex, the starting torque is small.

But as the brushless motor control technology is more and more sophisticated and mature, began to continue to popularize, instead of many brush motor, the future is mainly brushless motor, but no matter how to say, the advantages of brush motor is also there, and will not be eliminated.

Brush motor and brushless motor winding:

Brush motors generally use cross-winding method, you can use double flying fork equipment to wind the pair, winding efficiency is higher.

Brushless motors commonly have internal and external winding, the use of flying fork winding machine and needle winding machine to wind, and brush motors are still different, requiring more precision.

What is the difference between the advantages and disadvantages of brush and brushless motors? How is the stator and rotor wound? The above has made a simple explanation, I hope these tips will help you!
