PI manufactures electromagnetic linear motors and several types of piezoelectric linear motors.
Piezo Motors are intrinsically vacuum compatible, non-magnetic and self locking at rest, providing long travel compared to traditional piezo mechanisms. The individual drive concepts are optimized for different applications, they differ in their design, size, cost, force & speed and other performance parameters.
Piezo Inertia motors (stick-slip) are low-cost compact motors with forces to 10N and speed to 10 mm/sec.
Ultrasonic resonant motors (PILine®) are characterized by very high speed to 100’s of mm/sec and a very compact design.
