Energy consumption braking is a widely used electrical braking method. When the motor is separated from the three-phase AC power supply, the DC power supply is immediately connected to the two-phase winding of the stator, and the DC current flows through the winding to produce a stationary DC magnetic field. Below and three-phase asynchronous motor manufacturers Senli motor together to understand the next.

       The principle of energy braking isThree-phase asynchronous motorAfter the AC power supply is cut off, the rotor continues to rotate due to inertia, and direct current is immediately passed into the two-phase stator winding, which generates a static magnetic field in the stator.

       The guide bar in the rotor cuts this static field and generates an induced current, which is acted upon by the electromagnetic force in the static field. The torque generated by this force is opposite to the direction of inertia rotation of the rotor, called the braking torque, which forces the rotor speed to decrease.

       whenThree-phase asynchronous motorRotor speed reduced to0The rotor no longer cuts the magnetic field, the motor stops, and the braking ends. This method uses the energy of the rotor to cut the magnetic flux and generate the braking torque, which is essentially to consume the kinetic energy of the rotor on the resistance of the rotor loop, so it is called energy consumption braking.

       The advantages of energy consumption braking are strong braking force, stable braking and no big impact; The application of energy braking can make the production machinery accurately stop, and it is widely used in the production machinery such as mine lifting and crane transportation.
