Can DC brushless motors and generators be used interchangeably?

Many friends have always had this question, DC brushless motor can be used as a generator or not? Is there a possibility of replacing the two? With these curiosities, Vacuz gives you an introduction to it! I hope that can give you to solve the doubts!

How to say it, is certainly not, why? The reasons are as follows.

1. DC brushless motor and generator magnetism is different, the excitation coil can adjust the current size and direction, in the form of direct current. Generators are somewhat different, the direction of the current is fixed, running around a certain rule, the rotor to rotate, need current to excite, no armature power, two pieces of metal copper no contact, there will be a relatively large resistance, more dangerous.

2. The generator can supply itself with power and can realize the current self-sufficiency, the DC brushless motor can not, need to rely on 220V voltage to drive.

3. Safety requirements are also different, the protection measures are different.

As you can see, DC motors are actually not suitable for use as generators, leaving aside their own hardware, there is no way to generate electricity in the function; conversely, if the generator is used as a brushless motor, there is no way to achieve the speed control function, so it is also not suitable.
