Quais são as vantagens de desempenho do equipamento de motor sem escova CC?

With the rapid development of the motor industry, the application of DC brushless motor is gradually widespread. DC brushless motor has a series of advantages such as simple structure, reliable operation, easy maintenance, good speed regulation performance, etc. Its driver can control the rotor to maintain a certain speed and relatively stable performance.

DC brushless motor is actually a kind of low power motor, widely used in modern production equipment, instrumentation, computer peripherals and advanced household appliances, the rotor speed is mainly affected by the speed of its stator rotating magnetic field and the number of rotor poles. So what are the performance advantages of DC brushless motor equipment?

1. High efficiency

The efficiency of ordinary DC brushless motors is about 20% higher than that of traditional DC motors, not only in achieving high energy conversion, but also in energy saving. Long-term operation, DC brushless motor a year can save a lot of electricity costs, long-term use more effective. Although relative to the traditional DC brushless motor will be more expensive, but the energy-saving effect in the later years is very considerable.

2. Longer service life

Because brush motors have carbon brushes, so they need to be replaced regularly. Frequent maintenance and replacement will shorten its service life, the use of the effect will also be greatly reduced. DC brushless motor equipment, on the other hand, generally has a service life of more than 20,000 hours, and under normal use, the service life can reach 5 years, basically without damage, and its service life is more than 5 times that of traditional motors. DC brushless motor equipment has high precision of spare parts installation, smoother operation and smaller running sound. Because of its relatively small running sound, many medical devices use DC brushless motors, while traditional motors cannot achieve sealing performance, and the wear of carbon brushes will produce friction noise, which cannot meet the requirements of high silent devices.

These are the advantages of brushless DC motor equipment, compared to brush motors, not only in terms of performance, but also in terms of efficiency, life, have great advantages, and is also the reason why it is currently more popular.
