The difference between brushed and brushless motors
Brushless motor: Brushless DC motor is composed of the motor body and driver, and is a typical electromechanical integrated product. Due to the fact that brushless DC motors operate in a self controlled manner, they do not add additional starting windings to the rotor like synchronous motors that start with heavy loads under variable frequency speed regulation, nor do they generate oscillations and loss of step during sudden load changes. The permanent magnets for small and medium-sized brushless DC motors are now mostly made of high magnetic energy grade rare earth neodymium iron boron (Nd Fe-B) materials. Therefore, the volume of rare earth permanent magnet brushless motors is reduced by one frame number compared to three-phase asynchronous motors of the same capacity.
Brushed motor: A brushed motor is a rotating motor that contains a brush device to convert electrical energy into mechanical energy (electric motor) or mechanical energy into electrical energy (generator). Unlike brushless motors, brush devices are used to introduce or introduce voltage and current. Brushless motors are the foundation of all motors, with characteristics such as fast starting, timely braking, smooth speed regulation over a large range, and relatively simple control circuits.
