The QCI-L6 is a linear motor with full servo control, ideal for high acceleration moves—up to 8.4 G. The technology required to servo a rotary step motor is not that much different than that required to servo a linear step motor. Servoing a linear step motor retains all the advantages of servoing a rotary step motor. Servo control adds accuracy and repeatability, while eliminating the problems of resonance, stalling, and excess heating. The closed loop servo control increases the motor’s practical acceleration to over 8 G as compared to 1 G when operated open loop.
