Honey, I shrunk the motor
Piezo ceramic motors keep shrinking and PI's new motor is one off the tiniest yet still powerful
PI's patented P-653 piezo motor linear slide is significantly smaller than other miniature linear stages and provides significantly higher velocities and resolution. This true linear motor system (no conversion of rotation) consists of only 4 parts and can replace classical drive elements like miniaturised motor/lead screw systems or other linear motors, which P-653 outclasses with its speed of up to 200 mm/sec (8"/sec) and auto locking feature.
Measuring only 8.0mm in length, the new P-653 stage offers a travel range of 2mm and sub micron resolution, combined with a high holding force of 0.15 N (0.5 oz). Integration of the P-653 in an application is simple because the moving slider and the piezo motor are delivered assembled as a unit and already mounted on a PCB driver board requiring only 5 VDC supply voltage.
P-653-series PILine piezoelectric ultrasonic motor drives are ideal for OEM applications where quantities are high and space is at a premium. The systems were optimized for moving small objects such as optical fibres, micro optics, or micro electro-mechanical elements fast and precisely. These non magnetic ceramic motors (no lubricants) can also be used in medical applications,
Features & Advantages of the Ceramic Miniature Motors include:
True Linear Motor Slide / No Rotary Conversion Losses, Fast: Velocity up to 200 mm/s, Millisecond Responsiveness, Self Locking; Smaller, Faster, Fewer Components than Conventional Motors Travel Range 2 mm, Force Generation to 0.15 N, Cost-Effective OEM Drive for High Quantity-Applications, Preassembled and Mounted on a PCB Board Very Compact: Piezomotor Drive is Only 8 mm Long.
Motion is controlled by TTL voltage pulses applied to the driver electronics. The self adjusting driver creates the high-frequency, nanometre level oscillations (~500 kHz) that make the ultrasonic ceramic motor move.
At the heart of the system is a rectangular monolithic piezoceramic plate (the stator), segmented on one side by two electrodes. Depending on the desired direction of motion, the left or right electrode of the piezoceramic plate is excited to produce high frequency eigenmode oscillations of hundreds of kilohertz. PILine motors are vacuum compatible, non magnetic and self locking.
