PORTESCAP TURBO DISC® STEPPER MOTORS FEATURE UNIQUE MAGNETIZATION METHOD FOR UNPARALLELED STEPPER PERFORMANCEWOOD DALE, IL – Danaher Motion introduces Portescap Turbo Disc® Stepper Motors. These stepper motors feature an advanced, patented design for truly dynamic performance unrivaled by other stepper motor technologies. They are well suited for application in the medical, textile, die bonding and variable optical attenuator industries, among others.“The rotor consists of a rare earth magnet with a proprietary magnetization method that provides much smaller step angles than conventional two-phase permanent magnet stepper motors. The unique rotor design provides a very low moment of inertia for outstanding acceleration and dynamic behavior. Coupled with high peak speeds, any incremental movement is carried out in the shortest possible time,” says Dave Beckstoffer, Product Manager. Low inertia also results in high start/stop frequencies, which can solve certain motion challenges without applying a ramp.These motors feature a sinusoidal torque function with very low harmonic distortion and low detent torque, as well as excellent static and dynamic accuracy for any position, and under any load or speed conditions. An independent magnetic circuit eliminates the coupling between phases for superior angular resolution in microstep mode. An optimally-dimensioned iron circuit made of SiFe laminations, with coils placed near the air gap, significantly reduces iron losses and provides more torque at high step rates. The result is high peak torques, high speeds and high power/volume ratios.About Danaher MotionDanaher Motion is a leading global manufacturer of motion control products that improve the efficiency and productivity of complex manufacturing operations.
