Drive Motor Rotor: Service and Repair

IMA Motor Rotor Removal/Installation

Special Tools Required
Rotor puller 07YAC-PHM010B

The motor rotor contains very strong magnets and should be handled with special care. People with pacemakers or other sensitive medical devices should not handle the motor rotor.

WARNING: If the motor rotor is installed by hand, it may suddenly be pulled toward the motor stator with great force, causing serious hand or finger injury. Always use the special tool to remove or install a motor rotor.
- Keep the motor rotor away from magnetically sensitive devices.
- Do not blow air near the rotor, as metal particles may get on the magnet.
- Store the rotor in the designated storage box and keep it away from sensitive devices during storage.

1. Remove the transmission.




2. Remove the support (A).




3. Remove the sensor plate (A).

NOTE:
- When installing the sensor plate, check the insulating paint for damage.
- When removing the sensor plate, be careful not to touch the motor commutation sensor.




4. Slide the protector (A) in the direction of the allow, push the tab (B) then raise the lever (C). Remove the motor power cable (D) from the motor stator.

NOTE:
- If the motor power cable connector is dirty, clean it before removal.
- Cover the disconnected connector (E) with plastic (F), and wrap the motor power cable terminal with tape (G).
- If the motor power cable is wet, wait until it is dry before you wrap it.




5. Install a plastic film (A) between the motor rotor (B) and motor stator (C).




6. Remove three of the six bolts (A) as shown.




7. Install the rotor puller guide pins, then remove the remaining three bolts (A), and remove the rotor spacer (B).




8. Attach the rotor puller with the bolts supplied.

NOTE: When installing the rotor puller, position the puller to fit over the dowel pins (A).




9. Remove the motor rotor (A).




10. To prevent damage to the rotor magnet while working on the stator, place the rotor, with puller attached, into the puller case.




11. Install the parts in the reverse order of removal.

NOTE: Turn the handle of the special tool slowly when inserting the rotor into the stator. The rotor is drawn into the stator by magnetic force.

12. Remove the plastic film.
13. Reconnect the motor power cable to the motor stator.
14. Install the transmission.
15. Do the motor rotor position calibration procedure.
