POWERMAX II M Motors

K POWERPAC Hybrid Step Motors

The POWERMAX II M Motors boast unique features that set them apart in the market. Utilizing patented Sigmax® technology, these motors redirect magnetic flux to enhance torque production while minimizing leakage. Their rotor construction is tailored to specific needs: the "L" rotor design in the POWERMAX II M and P Series features laminated construction for high-speed efficiency, whereas the "J" rotor design offers low mass and low inertia, enabling fast start/stop and high acceleration capabilities.
