?The development of semiconductor electronics in the 1970s allowed the commutator and brushes to be eliminated in DC motors. In brushless DC motors, an electronic servo system replaces the mechanical commutator contacts. An electronic sensor detects the angle of the rotor, and controls semiconductor switches such as transistors which switch current through the windings, either reversing the direction of the current, or in some motors turning it off, at the correct time each 1···
In brushed motors, invented in the 19th century, this is done with a rotary switch on the motor's shaft called a commutator.
Shenzhen Power Motor has established a hair dryer/hair dryer R&D team since 2005, focusing on the development of household hair dryer motor solution. Our brushless motors have been mature and applied to the hair dryer/hair dryer to meet the requirements of different customers on the performance of hair dryer/hair dryer.
Since 2003, Shenzhen Power Motor has been gathering r&d resources of the group, establishing a vacuum cleaner r&d team, focusing on the research and development of vacuum cleaner motors, and had applyed brushless dc (BLDC) motors into vacuum cleaners to meet the requirements of different customers on vacuum cleaner performance.
Since 2010, Shenzhen Power Motor has collected research and development resources to set up the automobile micro-motor business division, focusing on the application and development of DC micro-motors in automobile parts, and has fully applied the integrated motor of brushless motor combined with gearbox into the tailgate.
Power Motor has been providing customized one-stop services for motors to customers all over the world since 2001. Up to now, the motor types designed and developed for customers include universal motor, brushed DC motor, brushless DC motor and gear motor. The four series of motor models are composed of motor type + chip size + voltage + serial number.
Our motors realize the quiet operation design through the special motor design method and material selection, greatly reducing the noise of the motor. Many factors need to be considered, such as the installation mode of the motor in the application, the operation load and speed of the motor, etc. Another consideration is the type of bearing selected for the motor or reduction motor. If there is a noise requirement for the application, the audible noise level of the motor or r···
In any mechanical or electronic system, as long as there is a continuous rotational motion, there is a motor.In modern automobile, comfort is as important as driving efficiency, and motor plays a key role.Whether it's the Windows, the seats, the steering wheel, the turbocharger, the hood or the brakes, every part has an electric motor. However, the motor does not start and stop on its own.Like many other automotive components controlled by electronic control units (ECU), ther···
