Rotary servo motor shaft shapes

Do not use shafts other than the straight shaft for frequent start/stop applications. Use a friction coupling or the like when
coupling the shaft with a machine.
There are six shaft shape types for the rotary servo motor: straight shaft, keyed shaft (with double round-ended key), keyed
shaft (without key), D-cut shaft, keyed shaft (with single pointed key), and L-cut shaft.
The keyed shaft (with single pointed key) supports only geared servo motors for high precision applications.
