INSPECTION
STEP 1
Check motor assembly for damage.
STEP 2
Set multimeter to continuity test.
STEP 3
Test continuity of motor leads and electro-magnetic brake leads (motor - lead shows in
diagram). Brake resistance should read 50ohms - 80 ohms.
STEP 4
Check all joints for bad connection, cracked or dry solder joints and oxidation.
STEP 5
Check that all the brushes can move freely in the brush guides with no obstruction (this can
be easily done by pulling on the free brush feeder wire).
STEP 6
Check that all the brushes are not chipped, cracked or worn.
STEP 7
Check that the brush spring is positioned to the centre of the brush body to apply even force.
Also check the brush spring tensions.
STEP 8
Check the condition of the brush feeder wire and check that the termination screws are
secure.
