3.3.3 Low-vibration motor
When compared to a general-purpose motor, a low-
vibration motor is designed to be insusceptible to time
harmonics and space harmonics and is improved in
machining accuracy to minimize gap imbalance. Hence,
this type of motor has achieved low oscillation of a
maximum 5 m full-amplitude and a maximum 1.5G
oscillatory acceleration. It is also wider in continuous output
range than a general-purpose motor.
