Brushed motor and brushless motor is our common two motors, the two applications are also relatively wide, many friends often take the two to compare, then what are the differences and advantages and disadvantages of brushed motor and brushless motor? Vacuz to introduce it! I hope it can help you!

Brushed motors and brushless motors have their own advantages and disadvantages and different, here are some of their main features:

Brushed motor main features:

I. Advantages:

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

2. Mature technology: Because of the long history of the development of brush motors, their control technology is relatively mature.

3. Large torque: under the same power, brushed motors can usually produce large torque.

II. Disadvantages:

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

2. Noisy: The friction between the carbon brushes and the commutator generates noise, making the brushed motor noisy during operation.

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

4. High interference: The alternating on and off of carbon brushes and commutator will produce electric sparks, which will interfere with the surrounding electronic equipment.

Main features of brushless motor:

I. 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: Since there is no friction between carbon brushes and commutator, brushless motors produce less noise during operation.

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

4. Low interference: Brushless motors do not produce sparks and cause less interference to the surrounding electronic equipment. Good speed regulation performance: brushless motors are easy to regulate speed and have a wide speed range.

Second, the disadvantages:

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

2. Higher price: Due to the higher technical requirements and manufacturing cost of brushless motor, its price is usually higher than brush motor.

3. Complex controller: Brushless motors need a special controller to realize electronic commutation, which increases the complexity and cost of the system.

What are the differences and advantages and disadvantages between brushed and brushless motors? Vacu has been briefly introduced above, I hope these tips can help you!
