Stepper Motors

Our high-performance, brushless, maintenance-free step motors provide very precise, extremely cost-effective motion control. These 2 phase step motors inherently move in small, very precise, 1.8° increments (200/revolution). This stepping action is simple to control and does not require complicated, expensive feedback devices.

With micro-stepping drives, each 1.8° step can be broken into even smaller increments. And, if position verification is required, motors are available with encoders. Several models feature the addition of our innovative SIGMAX® technology for higher torque and acceleration rates.

Due to their ease of use, simplified control needs and freedom from expensive feedback requirements, our step motors are excellent alternatives to pneumatic, hydraulic and servo motor systems.

POWERMAX M and P Series

Pacific Scientific POWERMAX II® P and M Series Step Motors set the standard for value in NEMA 23 (60 mm) step motors. They are available in half, single, and two stack configurations that provide holding torques from 42 to 253 oz-in. M Series Motors feature the addition of SIGMAX® technology for higher torque and acceleration rates.Learn More >

POWERPAC K and N Series

Pacific Scientific POWERPAC® N3, N4, K3, and K4 Series Hybrid Step Motors deliver more power in a smaller package. These rugged NEMA 34 and 42 (90 and 110 mm) frame motors provide among the highest torques per frame size in the industry. Optimal magnetics in a housingless frame combine with a large diameter rotor and new rotor-stator design to produce more torque, high acceleration, cooler running, and smoother microstepping. The K Series, which incorporates flux-focusing SIGMAX® technology, provides the highest acceleration rates and 25% more torque. Both the N and K Series are available with combinations of standard options to meet your specific requirements.Learn More >
