Reduction gear that provides a maximum rotation speed of 6,000 r/min against the rated rotation speed of 3,000 r/min. The maximum torque is applicable with 350% of the rated torque, and high torque is realized in the high rotation range. Torque ripple is substantially reduced by optimizing the combination of motor poles and slots, operating smoothly even at low-speed orientation when torque ripple’s effect is often greatest.
