Piezo Motion has developed a novel, low-power, high-performance rotary motor built around the piezoelectric principle that overcomes the limitations of conventional high-precision miniature DC stepper motors. It also opens new opportunities for motion control design within the medical devices and technology industries.

This whitepaper will discuss how the miniature piezomotor from Piezo Motion provides significant advantages in motion control applications that demand small size, high performance, precision motors.

Other key topics:

• The RAS Series provide superior precision and ultrafast response/start-stop characteristics; all within an affordable design.
• The rotary motor is highly energy-efficient and consumes zero power in hold position while still providing significant torque.
• The minimum step size of just 30 µrad, equates to >200,000 steps per full rotation of control.
• Unlike a microstepping stepper motor, which loses >70% torque during a microstep, the piezomotor maintains full torque during every step and provides ultra-smooth and silent rotation, ideal for medical devices.
