Wound rotor Inspection

Brushes should be inspected every 1000

running hours or at three monthly intervals if

this is a shorter period of time.

The inspection should include checks for

brush wear and tensioning. Build up of

carbon dust should be removed using a

suitable dust extraction unit.

Replacement of brushes is recommended

when the brush is approximately a quarter of

the way down the brush holder. On calliper

type designs the brushes should be replaced

when 1/4” (5mm) of brush remains.

It is important that the correct grade of brush

be used as this significantly affects operation.

If in doubt please refer to Brook Crompton.

Hazardous area motors

In addition to the conditions referred to,

special requirements apply to motor types

Ex N, Ex nA, EEx e, EEx d, EEx de. Refer to

the approval certificate and appropriate

codes of practice eg BS 5435.
