Energy consumption braking is also known as power braking, the energy consumption braking of three-phase asynchronous motor is to cut off the stator AC power supply of the motor to the DC power supply, so that the motor braking, the following with Senli motor Xiaobian understand together.

       When the equipment and machinery need to stop, the firstThree-phase asynchronous motorAt the same time, the DC power supply is connected with the stator winding, and a fixed magnetic field is generated in the motor. At this time, due to the inertia of the system, the rotor of the motor still continues to rotate in the original direction.

       By cutting the stator's fixed magnetic field and induced potential, the direction can be determined by the right hand rule, so that the rotor induced current, interact with the stator magnetic field, the torque generated and the rotor rotation direction is opposite, according to the left hand rule. A braking torque is generated.

       Under the action of the braking moment,Three-phase asynchronous motorStop quickly. Since this method converts the kinetic energy of the rotor into electrical energy for braking, it is called energy consumption braking.

       The three phase asynchronous motor adopts this braking mode, which has small energy consumption and stable braking. However, DC power supply is required, and this braking method is used in some machine tools.
