Regenerative braking: Regenerative braking differs from […]
Regenerative braking differs from both braking methods described above. Regenerative braking is only one working condition of the motor under special circumstances, and the above two are a method artificially applied to the motor for the purpose of rapid parking. Principle of regenerative braking: When the rotor speed of the motor exceeds the rotational speed of the synchronous magnetic field of the motor, the direction of rotation of the electromagnetic torque generated by the rotor winding is opposite to the direction of rotation of the rotor.
At this time, the motor is in a braking state. The reason why the state at this time is called regenerative braking is because the motor is in the power generation state, that is, the kinetic energy of the motor is converted into electric energy. At this point, certain measures can be taken to return the generated electrical energy to the grid. To achieve the purpose of energy saving. Therefore, regenerative braking is also called power generation braking.
