To upgrade machine performance or solve stalling problems, manufacturers often redesign motors with greater torque to reach greater accelerations for proper operations. Retrofitting a stepper motor, however, is time-consuming and expensive event, as it requires machining new mounting brackets and increasing the drive size and power supplies. PowerPlus Hybrid Stepper Motors from MOONS’ Industries eliminate the hassles of resizing motors by providing 25% to 40% more torque across the entire speed range of a motor. With the same physical dimensions as standard NEMA 23, 24 and 34 stepper motors, PowerPlus Hybrid Stepper Motors often drop into place to minimize upgrade costs while improving performance.

The increased torque of the PowerPlus technology is the result of higher motor efficiency. A higher magnetic flux density within the motor increases the performance of the PowerPlus Stepper Motor, enabling it to generate up to 40% more torque than conventional motors. Magnets placed between the stator teeth redirect and refocus most of the stray magnetic flux into the stator teeth to produce additional torque with the same input power.

In a typical application of upgrading stepper motor performance with PowerPlus technology, a manufacturer of CNC cutting systems wants to produce a high-performance version of its current machine to increase cutting speeds by 75% to 100% and improve move speed smoothly without resonance.

Engineering this new product, the CNC manufacturer wants to minimize engineering time while limiting parts inventory. A PowerPlus Stepper Motor provides twice the additional power over the existing motor needed for the new CNC machine without redesigning new parts. MOONS’ SR series micro-step stepper drive provides a wide range of output current with a compact size, the Anti-resonance function increases torque and the micro-step emulation provides smooth motion. In the meanwhile, Idle current reduction reduces motor heating. In fact, by using PowerPlus motors and SR drives, the machine builder can possibly use a smaller size motor and drive system to reach the same performance in a smaller and more cost-effective package.
