1.4 Servo motor shaft shapes
In addition to the straight shaft, the key shaft and D cut shaft are available as the servo motor shafts.
The key shaft and D cut shaft cannot be used in very 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 the
chapter of the servo motor series.
