For the motor, we often mention that the brush motor and the brushless motor, have many of the same products, such as pumps, power tools, electrical appliances, etc., there a difference between the brush and the brushless, so there are some comparisons, compared to the price, compared to the performance, compared to the quality, and there is how to wind the coil, wrap the stator or the rotor, these are some common knowledge problems. Now Grewin will give you a brief introduction. Hope to help everyone!
Advantages and disadvantages of a brushless motor
The difference between brushed motor and brushless motor:
The brush motor structure is relatively simple, the control is relatively easy, and the price is more affordable, but are equipped with reversing brushes, the use of mechanical reversing, with the continuous wear and tear of the work, will affect the life of the motor, the failure rate is relatively high, to a certain time will need to replace the carbon brush, and some places with relatively high requirements can not be used, will produce electrical sparks, prone to accidents.
The brushless motor uses electronic commutation, instead of mechanical commutation, longer service life, less failure, is basically free from maintenance, the working process will not produce sparks, is highly safe, and suitable for many high-precision places, the disadvantage is that the control loop is more complex, small starting torque.
However, because the brushless motor control technology is becoming more and more sophisticated and mature, it has begun to be popularized, replacing a lot of brushed motors, and the future is mainly dominated by brushless motors, but anyway, the advantages of brushed motors are also there, and they will not be eliminated.
Brushed motor and brushless motor winding:
The brush motor generally adopts the cross-winding method, which can be wound with double flying fork equipment, and the winding efficiency is higher.
The common brushless motor has internal winding and external winding, and the flying fork winding machine and the needle winding machine are used to wind, which is different from the brush motor and requires more precision.
Brushless motors are different
What are the advantages and disadvantages of brushed motor and brushless motor? How is the stator rotor wound? The above has made a simple explanation, I hope this knowledge to help you!
