Hengyang Heavy Industry's Electromagnetic Drum Brake DC MWZ400-1250 Has a High Action Frequency and Good Effect
As the contact gap continues to increase, the arc is broken again and the above charging and discharging process is repeated again. The discharge voltage gradually increases, and the voltage of capacitor C can reach tens of thousands of volts. Its Pulsed power is enough to damage semiconductor devices, and because it contains rich harmonic components, it will interfere with the control system and cause misoperation.
The external environment is also an important factor in the failure of electromagnetic brakes. For inductive coils, the selection of insulation materials and the prevention of short circuits are crucial, as short circuits are usually the result of insulation damage. The insulation life test of the inductance coil shows that vibration has little effect on the lifespan of the electromagnetic brake, and humidity is not the main influencing factor (humidity will slowly change the resistivity between windings, thereby shortening the lifespan of the electromagnetic brake), while thermal cycling is the main reason for reducing the expected lifespan.
Failure modes and results of inductance coils:
(1) Vibration effects: loss of sensitivity, breakage of parts and leads.
(2) Impact impact: lead breakage, loss of sensitivity.
(3) Temperature effects: warping, melting, instability, and changes in medium properties.
(4) Humidity impact: electrolysis, corrosion.
(5) Salt mist effects: corrosion, electrolysis.
