In the first part, we learned about the advantages and disadvantages of reverse braking, energy consumption braking, and feedback brakingThree-phase asynchronous motormanufacturerSenli Motor, for you to share the way and principle of regenerative braking, let's understand it together!
Regenerative braking yesAsynchronous motorIn a special case, a working state is a method applied on the motor by artificial means; When the speed of the rotor exceeds the rotation speed of the synchronous magnetic field of the motor, the rotation direction of the electromagnetic torque generated by the rotor winding of the motor is opposite to the rotation direction of the rotor, then it is in the state of braking.
The reason why such a state is called regenerative braking is because the asynchronous motor is in a state of power generation, which converts kinetic energy into electrical energy. When certain measures are taken to return the generated electric energy to the grid, the purpose of energy saving can be achieved, so we also call it power generation braking.
This braking method can generally be applied to two occasions, such as: frequency conversion speed regulation, the frequency is reduced at the same time the synchronous speed will be reduced, but because the rotor speed is the role of load inertia, it will not be immediately reducedAsynchronous motorIt will be in a regenerative braking state until the speed of the equipment decreases; Another is that when the heavy weight of the crane is falling, because the speed of the rotor under the action of heavy weight gravity, it may exceed the synchronous speed, and the electric machine is in a regenerative braking state, which can prevent the heavy weight from falling.
