14. SERVO MOTOR

14.2.5 Servo motor shaft shapes

In addition to the straight shaft, the keyway shaft and D cut shaft are available as the servo motor shafts.
The keyway shaft and D cut shaft cannot be used in frequent start/stop applications. Since we cannot warrant
the servo motor against fracture and similar accidents attributable to a loose key, use a friction coupling, etc.
when coupling the shaft with a machine.
The shaft shape of the standard servo motor changes depending on the series and capacity. Refer to section
14.6.4 and 14.7.4.
