How many kinds of braking modes are there in AC motors? What are the characteristics of each?
Energy consumption brakingWhen the motor cuts off the AC power supply, a DC power supply is added to any two of the stator winding to generate a stationary magnetic field, and the stationary magnetic field is generated by the inertia rotation of the rotor to produce a braking torque
Reverse brakingWhen the motor cuts off the normal power supply, the power phase sequence of the motor stator winding is changed so that a reverse braking torque is generated
Mechanical brakingBraking method using mechanical device to stop motor rapidly after stopping power supply. Such as electromagnetic brake, brake.
