Brushless DC motors are widely used in our daily life. They have certain applications in industry, automobiles, manufacturing, and computer peripherals. They not only have the speed regulation performance of DC motors, but also have stable operation and simple structure of AC motors. specialty. Let me introduce the advantages of the equipment.
1. The permanent magnets of DC brushless motors are now mostly made of rare earth NdFeB materials with high magnetic energy product. Therefore, the volume of the rare-earth permanent magnet brushless motor is reduced by one frame size than the three-phase asynchronous motor of the same capacity.
2. The motor has no mechanical commutator and adopts a fully enclosed structure to prevent dust from entering the motor and has high reliability.
3. The speed range is wide, and the motor can run in the low, medium and high speed range.
4. The brushless DC motor has the advantages of good low voltage characteristics, strong torque overload characteristics, large starting torque and small starting current.
5. Strong overload capacity to meet the needs of the vehicle's protruding stall. The braking effect is good. When the car is downhill or braking, the motor can completely enter the state of the generator, charge the battery, and at the same time play the role of electric braking, reducing the burden of mechanical braking. The small size, light weight and large specific power of the motor can reduce the weight of the equipment and save space.
6. The motor control system is simpler than the asynchronous motor.
