Where to apply your TurboDisc stepper The TurboDisc stepper provides the highest torque to inertia ratio and is ideal for applications requiring, fast and precise positioning. Focus On: Medical Analyzer Portescap’s challenge for the application was to provide maximum torque in a small diameter package. The higher speed capability of the TurboDisc allowed a higher gear ratio to be utilized, yielding an increase in output torque at the desired speed. The disc magnet design creates quick response time for the motor, increasing the throughput of the machine. Textile • Yarn monitoring system •...
