Braking means that the motor can stop working quickly when it is disconnected. likeBrake motorThree-phase asynchronous motors can produce braking performance, general motor braking can be divided into: mechanical braking, energy consumption braking, reverse braking. Below and Senli motor Xiaobian simple understanding.
Mechanical braking is after cutting off the power supply, the mechanical device can be used to make the motor quickly stop running, and the more common mechanical braking device used in production has two kinds of electromagnetic lock and electromagnetic clutch; Energy braking can make the motor accurate stop, such as in the normal operation of the three-phase asynchronous motor, DC power supply in its stator coil, will form a magnetic field, the rotor will continue to rotate and cut the magnetic field because of inertia, and the induction potential and point will be formed in the rotor, the direction of the torque is opposite to the direction of rotation, which becomes the brake, so that the operation of the mechanical brake, When the speed is zero, the braking torque is also zero, so it can be used well in situations where accurate positioning is required.
The positive and negative conversion is to switch any two of the three power lines in the stator, so that the torque output of the motor can be reversed, resulting in braking, or the series of large additional resistance on the rotor circuit can be quickly reversed, resulting in braking, this way the braking effect is strong, but the energy loss will be relatively large, and the accuracy is relatively poor.
Therefore, the braking of the motor is actually to stop the inertia force operation of the motor after stopping;Brake motor manufacturersIt is said that after the motor is cut off from the power supply, the electromagnetic torque (braking torque) can be generated in the opposite direction of the actual rotation of the motor, and the method of forcing the motor to stop quickly is called electric braking
