Let’s talk about the working principle of a DC motor: a ring-shaped permanent magnet is fixed inside the DC motor, and the current passes through the coil on the rotor to generate ampere force. When the coil on the rotor is parallel to the magnetic field, the direction of the magnetic field will change when it continues to rotate. Therefore, at this time, the brushes at the end of the rotor alternately contact with the conversion piece, so that the direction of the current on the coil also changes, and the direction of the Lorentz force generated does not change, so the motor can keep rotating in one direction.
In addition, DC motors are classified according to whether they have carbon brushes, and can be divided into DC brushed motors and DC brushless motors (high-power DC motors). The difference between a brushed DC motor and a brushless motor is whether it is equipped with a brush-commutator. The commutation of a brushed DC motor has always been achieved through the contact of graphite brushes with a ring commutator mounted on the rotor. And the DC brushless motor feedbacks the rotor position to the control circuit through the Hall sensor, so that it can know the exact time of the motor phase commutation.
Therefore, the DC motor can be either a brushed DC motor or a Brushless DC Gear Motors Manufacturers. What is the maximum W for a brushed high-power DC motor? That can be dozens of KW, while the maximum power of the brushless series of high-power DC motors can only be 3KW. The reason why Fujisaki Electromechanical specializes in the production of high-power DC motors are brushless series, because of the high demand for them in the emerging high-tech fields in recent years.
The “Made in China 2025” that everyone in the country knows, the intelligent manufacturing engineering, industrial strong foundation engineering, green manufacturing engineering, high-end equipment innovation engineering, etc. are all formulated for precision, high speed, high efficiency, environmental protection, low energy consumption, low noise and high technology. Demand for technology products. The brushless DC motor is an indispensable transmission mechanism for all kinds of automation, intelligence, industrial equipment, and manufacturing machinery. The brushless DC motor was born under the demand of such high-end technology products, but also serves those high-end technology products.
Compared with ordinary DC motors, the advantages of brushless DC motors: The motors have no brushes and commutators, which eliminates the disadvantages related to sparks generated by brushed DC motors, so they are cleaner, less noise, no maintenance, and longer life.
