14. SERVO MOTOR
14.6.4 Servo motors with special shafts
The standard shaft of the servo motor is straight without a keyway. Shafts with keyway and D cut are
also available. Except for the servo motor with reduction gear.
These shafts are not appropriate for applications where the servo motor is started and stopped frequently.
Use a friction coupling or the like with such keys since we cannot guarantee such trouble as broken shafts
due to loose keys.
