Five-Phase Stepping Motors

The RK Series five-phase stepping motor and drive package features a smooth drive function that employs microstepping within the driver independent of the controller output frequency for low vibration and low-noise operation at low speeds.

The motor's 72° angle can be electronically divided into a maximum of 250 microsteps. The driver provides sixteen resolution levels for both microstep low-speed operation and high-speed full-step operation. The system works with common power supplies including single-phase 110 to 115 Vac, 200 to 30 Vac, and 50/60-Hz types. Three stepmotor types are available: standard, IP65rated, and geared. The geared stepmotor types include tapered hob, planetary, and harmonic. The motors come in 42, 60, and 85-mm frame sizes that interface to the universal driver as stepmotors or geared stepmotors.
