What are the differences and advantages and disadvantages between brush motor and brushless motor? W

Brush motor and brushless motor are our common two kinds of motors, the application of the two is also more extensive, many friends often compare the two, then brush motor and brushless motor what are the differences and advantages and disadvantages? What are they? The following is a simple introduction to NOYU Hope to help everyone!
 

Brushed motor and brushless motor each have advantages and disadvantages and differences, the following are some of their main characteristics:

Brush motor main features:

1. Advantages:

1. Simple structure: brush motor structure is relatively simple, low manufacturing cost.

2. Mature technology: Due to the long development history of brush motor, its control technology is relatively mature.

3. Large torque: at the same power, brush motors can usually produce large torque.

2. Disadvantages:

1. Short service life: Due to the friction between the carbon brush and the commutator of the brushed motor, the carbon brush will wear out over time and need to be replaced regularly, thus affecting the overall service life of the motor.

2. Loud noise: The friction between the carbon brush and the commutator will produce noise, so that the brush motor will produce noise during operation.

3. Low efficiency: Due to the contact resistance between the carbon brush and the commutator, the energy conversion efficiency of the brushed motor is relatively low.

4. Large interference: the alternating on and off of the carbon brush and the commutator will produce electrical sparks, which will interfere with the surrounding electronic equipment.
 

Main features of brushless motor:

1. Advantages:

1. Long life: brushless motors use electronic commutation, so there is no problem of carbon brush wear, so they have a longer life.

2. Low noise: Because there is no friction between the carbon brush and the commutator, the brushless motor produces less noise during operation.

3. High efficiency: Because there is no contact resistance between the carbon brush and the commutator, the energy conversion efficiency of the brushless motor is usually higher than that of the brushed motor.

4. Low interference: brushless motor will not produce sparks, less interference to the surrounding electronic equipment. Good speed control performance: brushless motor speed control is convenient, wide speed control range.

2. Disadvantages:

1. Complex structure: The structure of brushless motor is more complex and the manufacturing cost is high.

2. High price: Due to the technical requirements and high manufacturing costs of brushless motors, their price is usually higher than that of brushed motors.

3. Complex controller: brushless motor requires a dedicated controller to achieve electronic commutation, which increases the complexity and cost of the system.
 

What are the differences and advantages and disadvantages between brush motor and brushless motor? What are they? The above has been a simple introduction, I hope these little knowledge can help you!
