Rotary servo motor shaft shapes

There are three shaft shape types for the rotary servo motor: keyed shaft (with double round-ended key), keyed shaft (without
key), and D cut shaft.
To prevent damage to the shaft, do not use the keyed shaft (with double round-ended key), keyed shaft (without key), and D
cut shaft for frequent start/stop applications. Use a friction coupling or the like when coupling the shaft with a machine.
