6–MOUNT THE MOTOR

Use flange bolts to mount rotary step motors. The pilot, or centering flange on the motor’s front face, should fit snugly in the pilot hole.

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 multi- plied by a much longer lever arm.

Step Motors can produce very high torques and accelerations. If the mounting is inadequate, this combination of high torque/high accelera- tion 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 vibra-
