Danaher Motion Intros Portescap Turbo Disc Step Motors

Danaher Motion (Radford, VA), a strategic business of Danaher Corp. (Washington, DC), introduced its Portescap Turbo Disc™ stepper motors, which feature an advanced, patented design for application in the medical, textile, die bonding and variable optical attenuator industries, among others.

The motors feature a sinusoidal torque function with low harmonic distortion and low detent torque, as well as static and dynamic accuracy for any position, and under any load or speed conditions. An independent magnetic circuit eliminates the coupling between phases for angular resolution in microstep mode. An optimally dimensioned iron circuit made of SiFe laminations, with coils placed near the air gap, reduces iron losses and provides more torque at high step rates. The result is high peak torques, high speeds and high power/volume ratios.
