αSTEP/Stepper Motor: Motor Section of the Stepper Motor

In the web general catalog, we introduce a lineup of products that consist of a combination of 5-phase motors and drivers. All the featured products include a 5-lead wire motor with a new pentagon wiring and a driver equipped with a dedicated excitation sequence. This unique combination has enabled us to achieve the following:

  • Simple 5-Lead Wiring
  • Reduced Vibration


Here, we will explain the wiring and excitation sequence.

New Pentagon Wiring 4-Phase Excitation Mode: Full Step

0.72°/step
It employs a unique method of continuously exciting 4 phases at a time in a 5-phase motor, with a step angle of 0.72° per step. It has a significant damping effect, allowing for stable operation.
