Which of the brushed DC motor and the brushless DC motor has more force?

The torque of the micromotor is an important reference factor. The brushless motor of the brushless motor and the DC motor is divided into two parts. Under the same conditions, the force of a brushless motor is greater than that of a brushed DC motor.

Judging from the working principle of the original DC motor, brushes and brushless are basically the same. The main difference is that the brushed DC motor uses mechanical commutation, while the brushless DC motor uses electronic commutation. Therefore, the force of a brushless DC motor will be greater than that of a brushed DC motor.

Features of brushless DC motor:

1. Small size, light weight, large torque;

2. Good torque characteristics, good medium and low speed torque, large starting torque and small current;

3. Cover the performance advantages of brushed DC motors, cancel the carbon brush structure, and have a longer service life, generally up to hundreds of thousands of hours;

4. Since there is no excitation loss and carbon brush loss, the efficiency of DC motors is much higher than that of carbon brushes.

5. Stepless speed regulation can be adopted, with strong overload capacity and wide speed regulation range;

The brushless DC motor has no mechanical brush device. It uses Hall sensors instead of brushes and commutators. The material uses neodymium iron boron permanent magnet materials, so it has advantages over brushed DC motors in terms of performance, high efficiency and energy consumption. Low, low noise, long life, high reliability, good servo control and other advantages, stepless variable frequency speed regulation is the core advantage of brushless DC motors.

Although the performance of the brushless DC motor is better, the control is not as convenient as the brushed DC motor. The control is more complicated and the cost is relatively high. Therefore, when the brushless smart motor can meet the parameter requirements, most of them still tend to choose Brushed DC motor.
