7.7 Motor replacement
Note: In the case of motors of the A4 model series , the rotor is shrunk
directly onto the worm shaft. This means the rotor can only be replaced with
the worm shaft. For this reason, the motor should only be replaced
in the
plant .
Disassembly:
Disconnect the power from the installation and secure the car and
counterweight.
Attach and secure the motor to the lifting gear.
Unplug the electrical connections and lines from the motor (motor and
magnetic clamp connections).
Remove the nuts from the motor, brake and coupling disc.
Comply with the installation instructions for the flexible coupling in Appendix
9.
Carefully pull the motor from the studs and place on the ground.
Installation:
Compare the motor data of both motors.
Attach and secure the replacement motor to the lifting gear.
Raise the motor using the lifting gear and align the motor coupling and brake
disc. The locations of the mounting holes must match those of the screws.
Push the motor and coupling on the gear drive onto the brake disc and
intermediate flange. Screw in and tighten the screws evenly with the
prescribed torque (see table with tightening torques 9 in the Appendix).
Note: Comply with the assembly instructions for the flexible coupling SA14 in
chapter 9.
