Brushless DC motor

l  Profile

Brushless DC motors consists of the motor body and controller, is a typical mechatronic products. Because brushless DC motor is running self-controlled, so it does not like synchronous motors under heavy starting with frequency conversion to variable speed, which is added starting additional winding on the rotor, and it will not be out of step and oscillate at the time of mutation load. The permanent magnet of small and medium-capacity brushless DC motor is always more high energy product rare earth neodymium iron boron (Nd-Fe-B) materials. Thus, the volume of rare earth permanent magnet brushless motor is far smaller more than the three-phase asynchronous motor with same capacity.

Brushless DC motor has the DC brush motor characteristics and the frequency change devices, so they are called DC frequency conversion, the international generic term is the BLDC. The operating efficiency, low-speed torque and speed accuracy of brushless DC motor is better than any inverter control technology.

Electrical Performance

The Curve of Performance

The advantage of the brushless motor:

1. Brushless, low interference

Brushless motor eliminates brushes, the most immediate change is that there is no spark generated when the motor is running, thus greatly reducing the spark radio interference.

2. Low noise, smooth operation

Brushless motor has no a brush, the friction is greatly reduced in running, and smooth operating; noise will be much lower, this advantage is a huge support for the model running stability.

3. Long life, low maintenance costs

There is no brush, so the main loss of brushless motor is from the bearing, at the mechanical point of view, the brushless motor is an almost none maintenance electric motor, and when necessary, you can only clean some dust.
