Solenoid brake troubleshooting methods? Electromagnet type brake is widely used in engineering machinery because of its convenient loading and unloading, good response performance, high reliability, and environmental protection.

Electromagnet brake contacts disconnect the inductive circuit, theoretically, the inductor current suddenly interrupted, the inductor will have a back-EMF at both ends, because the current rate of change is great, so the two ends of the inductor will tend to infinity Reverse voltage. When the arc is pulled to a certain distance and off, the contact disconnected.

Electromagnet type brake is the most important component of the inductor coil, an important feature of the inductor circuit is off instantly, in particular, will have a strong moment of breaking induced electromotive force. This electromotive force is usually several times the normal operating voltage to several hundred times.

Electromagnetic brake The external environment is also an important factor in the failure of the solenoid brake. For inductors, the choice of insulation and short-circuit prevention is the key, short circuit is usually the result of insulation damage, and thermal cycling is to reduce the life expectancy of the most important reason.
