What is a brushless dc motor controller

The previous article, small make up from the four big advantage of the brushless dc motor controller, how to run the brushless motor controller, brushless and has the difference of brush motor controller, and other side, briefly discusses some knowledge about the brushless dc motor controller. Perhaps you for brushless dc motor controller the concept itself is not too clear, so focus on what is today the brushless dc motor controller.
from the nature of the motor controller, motor controller is to achieve energy conversion, the nature of the circuit using the letters M ( Old standards with D) Said. Its main function is to produce drive torque, as with all electrical appliances or mechanical power. Generator controller circuit with the letter G said. Its main function is to use mechanical energy into electricity, is currently the most commonly used, heat energy, water, etc to move the rotor of the generator controller is used to send electricity respectively.
as early as the birth of the motor controller of the last century, there appeared the brush motor controller and two forms of brushless motor controller, in terms of practicality is the brushless form, namely ac squirrel-cage asynchronous motor, this motor has been widely used. But asynchronous motor has many not be able to overcome the defects, so that the motor controller technology developed slowly. By the middle of the century was born the transistor and the transistor commutation circuit instead of brush and commutator of the brushless dc motor controller was born. This new type of brushless motor controller called electronic commutator dc motor controller, the brushless dc motor controller, it overcomes the defects of the first generation of brushless motor controller.

of course, the brushless dc motor controller with a dc motor controller is often appear together, the primary difference between them is the brushless motor controller does not use mechanical brush device. A controller of brushless dc motor reversing has been through graphite brush and mounted on the rotor commutator ring in contact. And brushless dc motor controller to put back the rotor position feedback control circuit, the hall sensor to be able to learn the exact time of the motor controller phase commutation. Most of the brushless motor controller manufacturers production positioning controller has three hall effect sensors. As there is no brush brushless motor controller, so also does not have relevant interface, therefore more clean, less noise, in fact, no maintenance, longer life.

the brushless motor controller of English abbreviations is BLDC, motors in our country, the development of the time is short, but as the technology increasingly mature and perfect got rapid development. Has been used in model aircraft, medical equipment, household appliances, electric cars, and other fields is widely used, and in, hangzhou, wenzhou and other places form a certain scale of industrial chain. In recent years, the brushless motor controller become a rapid development in the field of the model of a kind of power. Because of production and price, over the past few years brushless motor controller used in high-grade aviation model, now due to the rapid development of machining technology, brushless motor controller of lower production costs a lot of, it is into the model in the field of all levels, from electric remote control cars to electric remote control boat to electric model planes, everywhere.
