The brake of the motor when how to return a responsibility?

Brake pads (mechanical brake);Electromagnetic brake,braking,reverse connect braking energy

consumption (electromagnetic brake) Brake pads,the principle of the most simple,the collapse of the motor can understand.Electromagnetic brake:the power of the motor and the electromagnetic brake is synchronous,electromagnetic brake power from the motor of the junction box or contactor,the working principle of electromagnetic brake:www.facebook.com/dongfeng.motor electricity,the

electromagnetic brake device separately,the motor can rotate,power failure,due to internal lose

magnetism,spring to close brake device,motor stalling.Braking energy:the so-called braking

energy,namely after the motor out of three-phase ac power supply,the stator winding with a dc

voltage,namely into the dc current,using the rotor induced current and the effect of static magnetic

field has reached the purpose of the brake.Reverse connect braking:in the motor to cut off the normal

operation of the power supply at the same time change the power of the motor stator perkins

diesel generator setwinding phase sequence,make it have a reverse trend to produce a larger

braking torque method. The essence of the reverse connect braking,tried to make motor brake,so when

the rotating speed of the motor is close to zero,shall be immediately cut off the switching of brake

power,otherwise electric induction motor opportunity to reverse. Speed relay is used

to automatically cut off in the actual control of braking power.This is not full!
