Can brushless motors be used as generators? What is the difference between the two and how do they differ? - CE Certificate Automatic Stator Motor Transformer Toroidal Coil Winding Machine Manufacturer -Vacuz

Brushless motor stator coil and generator coil look somewhat similar, many friends then asked, brushless motor can be used as a generator? With skepticism, has been more curious, so brushless motor in the end can be used as a generator? Vacuz briefly gives you an analysis of it!

1, the magnetism of the motor is different from the magnetism of the motor, divided into excitation and self-excitation, there is an excitation coil to regulate the size and direction of the current, rotating magnetic field coil is supplied with DC current around the wire resistance, reversible current to change its current direction in the same way.

2, the motor voltage and current follow a fixed straight line, the electromagnetic environment also follows a certain trajectory, the motor does not have carbon brushes, that is, the need to transfer the armature voltage to the motor rotor, so that the rotor rotation, the need for current energization, if there is no armature power supply, the two metal copper pieces in the non-contact will produce strong resistance, which is more dangerous to a certain extent.

3, brushless motor can not supply its own power, power self-sufficiency can be achieved through power generation. Its current and voltage is still driven by 220 volts, in measures, they take different protection measures.

4. If the motor is developed, only its function is considered, and its hardware cannot realize the power generation function. If the motor is used to run the brushless motor, the cycle and physical conditions are not adapted, and the speed control function can be realized by the existing method.

5. Brushless DC motor is different from brush DC motor, it does not use mechanical brush device, but square wave self-control permanent magnet synchronous motor, using Hall sensor instead of carbon brush commutator, using neodymium iron boron as permanent magnet material of rotor, its performance is better than conventional DC motor, it is a common speed control motor now.

6、The essence of brushless motor is a kind of permanent magnet synchronous motor with position feedback, and the input is converted into three-phase AC power by inverter.
