Mounting & Coupling the Motor
WARNINGS
•
Improper motor mounting and coupling can jeopardize personal safety, and compromise system performance.
•
Never disassemble the motor; doing so will cause contamination, significant reduction in magnetization, and loss of
torque.
•
Improper shaft machining will destroy the motor’s bearings, and void the warranty. Consult a factory Applications
Engineer (see phone number on inside of front cover) before you machine the motor shaft.
Mounting the Motor
Use flange bolts to mount rotary step motors. The pilot, or centering flange on the motor’s front face, can help you
position the motor.
Do not use a foot-mount or cradle configuration, because the motor’s torque is not evenly distributed around the motor
case. When a foot mount is used, for example, any radial load on the motor shaft is multiplied by a much longer lever arm.
The motors can produce very high torque and acceleration. If the mounting is inadequate, this combination of high
torque/high acceleration can shear shafts and mounting hardware. Because of shock and vibration that high accelerations
can produce, you may need heavier hardware than for static loads of the same magnitude.
Under certain move profiles, the motor can produce low-frequency vibrations in the mounting structure that can cause
fatigue in structural members. A mechanical engineer should check the machine design to ensure that the mounting
structure is adequate.
