AC electromagnetic brake
AC electromagnetic brake

AC brake widely used in metallurgical, construction, chemical, food, machine tools, packaging machinery without rectifier

  JSDZ series of electromagnetic exchange loss of brake power, and the main faction supporting Y Series motor generates electromagnetic brake YEJ series of three-phase asynchronous motor. Widely used in metallurgical, construction, chemical, food, machine tools, printing, packaging machinery. Applicable to stop the rapid, accurate positioning, frequent start-up, power down when the safety brake (anti-risk) and so on.

Fault

Processing method

1,Brake don’t work when energized

1,Check AC power fault.

2,Work air gap larger.

2,one sucked when brake energized

the other don’t sucked

1.check brake’s movement component if was bite or other goods .

3,brake when energized ,brake disc begin smoking

1,Work air gap adjust smaller.

2,Work air gap don’t equality.

3,Friction disc have reached wearproof limit and need change it.

4,Brake don’t work

1,dynamic moment of inertia large of work system,brake torque small.

2,Work air gap larger,should adjust air gap.

3,brake disc surface have greasy dirt,need washing it.

4,Spring tired,break out,need chang it.
