1. Market overview of motors

In recent years, there has been a trend for brushless DC motors to replace brushed DC motors. The brushless DC motor uses electronic components to replace the traditional carbon brush commutation, which will solve the shortcomings of the brush motor. Because brushless motors do not have carbon brushes, they have very little noise during the working process. This will highlight their advantages in quiet places such as hospitals, schools, banks, etc. Because brushless motors do not have carbon brushes, there will be no sparks in the working process, which makes Brushless DC motors show their talents in some flammable and explosive occasions, and one more important thing is their long life, because the friction of the carbon brushes of the brushed motors will make the carbon brushes easy to damage, and the life of the brushless motors will be longer than that of the brushes. The motor has a much longer life, because the brushless motor uses the induction of the magnetic field without substantial contact, so the speed of the brushless motor is faster.

2. Market pain points

Brushless DC motors also have their corresponding shortcomings. Brushless DC motors must be equipped with a corresponding DC motor speed controller to work. This will increase the cost of work. It is only the commutator for the motor. The cost is much higher than that of carbon brushes.

3. In response to market needs and pain points, Lihui provides solutions and results

Based on solving the problems of existing motors, Lihui Company designed a thyristor speed-regulating motor to fill the market demand. The SCR speed control motor is an AC motor that uses a bidirectional thyristor to turn off to control the speed. The SCR speed control motor has the functions of speed control and speed feedback with the DC brushless motor. Relative to DC brushless motor: The SCR speed control motor controls the speed of the motor by controlling a bidirectional thyristor to turn off. Therefore, the cost of the SCR speed control motor is much lower than that of the DC brushless motor; relative to the DC brushless motor Motor: SCR speed control motor has speed regulation and speed stabilization functions. Therefore, SCR speed control motor is more cost-effective than other motors.
