Checking for efficiency

1. Check the connector blocks (wiring) and check for any bent or detached terminals.
2. Check for traces / residue / deposits of water or detergent and identify their source.
3. Check for any windings / components connected to mass or inadequately earthed using a tester with a
minimum scale of 40mW across each terminal and the casing (correct reading is ∞).
4. Check the individual windings against the values shown in the table below:
Terminals on
motor
connector
block
3 - 4
5 - 10
6 - 7
8 - 9
1 - 10
( ) excluding the resistance of the brushes
Notes:
- When checking the rotor winding, measurement should be effected around the entire surface, turning
the spindle very slowly and checking for any short-circuits between visible plates. Also check the carbon
brushes for wear.
- If noise is generated (bearings-magnet-belt), detach the drive belt from the pulleys and locate the
source.
