1. New or long-term stopped using motor should be inspected winding and insulation resistance to earth before motor operation. The voltage of motor below 500V often uses 500V insulation resistance meter; The voltage below 500V-1000V often uses 1000V insulation resistance meter; The motor voltage above 1000V often uses 2500V insulation resistance meter. The working voltage of insulation resistance mustn’t less than 1MΩ per KV and should be measured under motor cooling status.

2. Checked if the surface of motor has crack or not, fastening screws and spare parts are all in readiness, and if motor fixed situation is good.

3. Checked if the motor drive mechanism is reliable.

4. According to the data indicated on the nameplate, such as voltage, power, frequency, coupling, speed if is matached with the power supply and load.

5. Checked if the motor ventilatation and bearing lubrication is going well.

6. Pull the motor axis, checked if the rotor could rotation freely and has any nosies when it is rotated.

7. Checked the brush assembling condition and if the bursh-lifting device is flexible and the position of brush-lifting hand shank is right.

8. Checked if the motor earthing device is reliable.
