TurboDiscTM disc magnet stepper motors
Portescap TurboDisc motors provide exceptional dynamic performance unparalleled by any other stepper on the market. The unique thin disc magnet enables finer step resolutions in the same diameter, significantly higher acceleration and greater top end speed than conventional steppers. TurboDisc motors excel in applications that require the precision of a stepper and the speed/acceleration of a DC motor.
TurboDisc motors provide the highest torque to inertia ratio and are ideal for textile systems, factory automation equipment, medical and lab automation, and other industrial applications and machinery. |
