With the development of science and technology, motors are becoming more and more advanced, and the brush motor, which used to be used a lot, is gradually replaced by brushless motor, especially brushless DC motor, so why choose brushless motor? What are the advantages over brush motors?

Brushless DC motors have the advantages of simple structure, stable operation and easy maintenance of AC motors, but also have the advantages of superior speed regulation and high operating efficiency of DC motors, which are widely used in automotive, aerospace, household appliances, model drones, electric tools and other industries, and are favored by our friends.

1. Brushless DC motor high efficiency, more energy saving

Compared with brush, small size brushless motor can provide more power under the same torque; the efficiency of brushless DC motor can reach more than 96%, while ordinary DC motor is only about 75%, relatively speaking, brushless DC motor is more energy-saving and more cost-effective for long-term use.

2. Brushless motor has long life

Brush motor due to the existence of carbon brushes, will cause wear and tear, every now and then need maintenance, replacement, while brushless motor without carbon brushes, maintenance-free, service life is more than 5 times the traditional motor.

3. Low running noise

Brushless motors run smoothly, the noise is below 50db, so some medical machines, household appliances mostly use DC brushless motors; traditional motors have carbon brush wear, noise in more than 60db, can not meet the high performance needs of the silent environment.

4. Safety and durability

Brush motor brush and commutator contact will wear, may produce electric sparks, strong words will also cause electrical noise; and brushless motor to solve the commutation spark problem, can be used in explosive and other harsh environments.
