When mounting couplings or pulleys to the shaft, verify that the connections are properly
aligned and that axial and radial loads are within the motor specifications.
A shaft key provides a rigid mechanical connection with the potential for self-alignment, but the
key must be properly installed in the keyway. The
section provides sizing
information on the key and shaft keyway. Refer to the
Shaft Key Removal and Installation
section for recommendations on how to remove and install a shaft key.
Requirements for Mounting
HPK-Series asynchronous motors have a mounting pilot for aligning the motor on a machine.
The installation must comply with all local regulations and use of equipment and installation
practices that promote electromagnetic compatibility and safety.
•
The motor shaft and the load shaft must be parallel and pulleys aligned.
•
Pulleys, gears, and similar devices should be mounted as close as practical to the front
motor bearing to minimize bearing load.
•
Flexible couplings may be used between the motor shaft and a load shaft. The motor
shaft and load shaft must be aligned to values recommended for the specific coupling
before coupling is connected.
•
Stainless steel fasteners are preferred for mounting the motor.
ATTENTION: Do not strike the shaft, key, couplings, or pulleys with tools
during installation or removal.
Damage may occur to the motor bearings and the feedback device if sharp
impact to the shaft is applied during installation of couplings and pulleys, or a
shaft key. Damage to the feedback device also may result by applying leverage
from the faceplate to remove devices mounted on the motor shaft.
To remove a friction-fit or stuck device, apply a constant pressure to the user
end of the shaft with a wheel puller.
Failure to observe these procedures could result in damage to the motor and its
components.
ATTENTION: Unmounted motors, disconnected mechanical couplings, loose
shaft keys, and disconnected cables are dangerous if power is applied.
Disassembled equipment should be appropriately identified (tagged-out) and
access to electrical power restricted (locked-out).
Before applying power to the motor, remove the shaft key and other mechanical
couplings that could be thrown from the shaft.
Failure to observe these safety procedures could result in personal injury.
