After the motor is separated from the three-phase AC power supply, a DC voltage is added to the stator winding, and the direct current is passed into the direct current, and the action of the rotor induced current and the static magnetic field is used to achieve the purpose of braking. Here is a small series with Senli motor to understand the next.

       inThree-phase asynchronous motorDirect current passes through the stator windings to generate a fixed and constant magnetic field. At this point, the rotor cuts the magnetic field line in the direction of rotation, resulting in a braking torque.

       Because this braking method is not like regenerative braking, the energy generated during braking is returned to the power grid, but the kinetic energy is consumed by the motor alone, so it is called energy consumption braking. And because the stator winding through the direct current to brake, so energy braking is also called DC injection braking.

       Energy braking is solely dependentThree-phase asynchronous motorTo consume kinetic energy to achieve the purpose of stopping, so the braking effect and accuracy are not ideal. In some occasions requiring short braking time and good braking effect, this braking method is generally not used. Like lifting machinery, its operation is characterized by low motor speed, frequent start, stop and reverse rotation, and drag the lifting weight to run.

       In order to achieve accurate and flexible control, the motor is often in the braking state, and the braking torque is required to be large. However, energy consumption braking can not meet the above requirements.
