IMA Motor Rotor Removal/Installation

Special Tools Required 

Rotor Puller 07YAC-PHM010C

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 IMA motor rotor.

WARNING: If the rotor is installed by hand, it may suddenly be pulled toward the stator with great force, causing serious hand or finger injury. Always use the special tool (rotor puller) to remove or install the rotor assembly.
  • Keep the motor rotor away from magnetically sensitive devices.
  • Do not blow air near the rotor, as metal particles may get on the magnets.
  • Store the rotor in the designated storage box, and keep it away from sensitive devices during storage.
  1. Remove the transmission (see TRANSMISSION REMOVAL ).
  2. Remove the support (A).

  4. Turn the ignition switch to LOCK (0). Turn the battery module switch OFF (see DISCONNECTING THE MOTOR POWER CABLE CONNECTOR FROM THE MOTOR STATOR  ). Slide the protector (A) in the direction of the arrow. Push the tab (B), then raise the lever (C). Remove the IMA motor power cable (D) from the motor stator.
    NOTE:
    • If the IMA motor power cable connector is dirty, clean it before removal.
    • Cover the disconnected connector (E) with a plastic bag (F), and wrap IMA motor power cable terminals with insulating tape (G).
    • If the IMA motor power cable is wet, dry it with a clean shop towel before you wrap it with tape. Do not use compressed air.

  8. Attach the rotor puller with its supplied bolts.
    NOTE: When installing the rotor puller, position the puller to fit over the guide pins (A).

  11. Install the parts in the reverse order of removal.
    NOTE:
    • When installing the rotor, install the special tool to the rotor and set the rotor with the tool tip stretched out.
    • 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 IMA motor power cable to the motor stator.
  14. Reinstall the drive plate.
  15. Reinstall the support.
  16. Install the transmission (see TRANSMISSION INSTALLATION ).
  17. Do the motor rotor position calibration procedure (see IMA MOTOR ROTOR POSITION CALIBRATION  ).
