Cable Leading Direction

Cable Leading Direction

Cables for power, encoder, and electromagnetic brake are capable of being connected either in direction or in opposite direction of the load side, depending on the cable selection. (HG-KR and HG-MR series)

Reduced Torque Ripple during Conduction

■Torque ripple

Torque ripple

The torque ripple is reduced owing to the optimized combination of the numbers of the motor poles and the slots. Thereby, smooth rotation is achieved even during a low-speed operation which is more likely affected by the torque ripple, improving the operation stability.
