Tips: Difference between brushed and brushless DC motor

1. Brushed dc motor is a device to convert electrical energy into mechanical energy or convert mechanical energy into electrical energy. BDC motor is the basis of all motors, it has the characteristics of fast start, timely braking, and smooth speed regulation in a large range, relatively simple control circuit and so on. Brushless dc motor is a typical mechatronics product, which is composed of motor body and driver. Because the brushless DC motor is operated in automatic control, it will not add the starting winding on the rotor like the induction motor started under the frequency conversion speed regulation, and it will not oscillate and lose step when the load suddenly changes. Small and medium capacity BLDC motor permanent magnet, now more use of high magnetic energy product of rare earth Nd-Fe-B material. Therefore, the volume of this is a smaller frame than that of the same capacity three-phase induction motor.
2. When the brushed motor work, coil and commutator rotates, magnetic steel and carbon brush does not turn. The alternating change of coil current direction is with the motor rotation of the commutator and brush to complete. There are a lot of differences between brushed and brushless motors. As you can see from the name, brushed motors have carbon brushes while brushless motors have no carbon brushes.
3. Brushed motor is a traditional product with relatively stable performance. Brushless motor is an upgrade product, however, its control circuit is more complex, and the aging screening of components is strictly required. Although the motor has a long life, the control circuit is prone to failure. Therefore, the selection of brushless motor to go through strict reliability test to ensure quality. However, as the technology continues to upgrade a few steps, brushless motor technology has been quite mature.
4. In the actual production process, the brushed DC motor is a high-speed motor with small gear teeth and easy to wear, but the strength is large and the climbing ability is strong. The brushless DC motor can save the cost of replacing the carbon brushes. However, high precision is required in the process of controlling the BLDC motor, and its controller is expensive. In contrast, the brushed DC motor with gearbox is cheaper and easier to control than brushless DC motor.
5. brushed motor refers to the motor is a direct current input, the controller only to provide it with the size of the current can be adjusted. Brushless motor is actually a three-phase AC motor to convert direct current into three-phase AC through the controller and make the motor normal operation according to the Hall sensor in the motor for commutation. To put it bluntly, brushless motors have a longer life and a more efficient start, but its controller costs more than brushed controller.
