Rotary servo motors with special shafts

For rotary servo motors, there are four types of shafts: D-cut shaft, L-cut shaft, keyed shaft (with double round-ended key),
and keyed shaft (without key).
To prevent an accident such as motor shaft fracture, do not use a servo motor with a D-cut shaft, L-cut shaft, or keyed shaft for
frequent start/stop applications.
For geared servo motors with special shafts, refer to the following.
