Micro-Stepping Driver/Motor Takes Little Space

Targeting space-limited machine designs, the PRO Series NEMA 17 integrated motor/drivers exhibit a 42-mm footprint with attached drive electronics in RoHS-compliant packages. Two models, the PRO 42AP 1/500 and PRO 42BP 1/8, are said to provide high torque densities and simple operation via attached drive electronics. The motors are available in case lengths of 40, 48, and 60 mm and, depending on the case length, they can produce maximum holding torques (bipolar) ranging from 300 to 440 mNm. Single-unit prices range from $171 to $257 depending on model and case length. NIPPON PULSE AMERICA INC., Radford, VA. (540) 633-1677.
