Reaches Speeds Up to 200 mm/sec (8 in./sec)AUBURN, Mass, May 8, 2008 -- Physik Instrumente (PI) LP said its 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 four parts and can replace classical drive elements like miniaturized motor/lead screw systems or other linear motors, which P-653 outclasses with its speed of up to 200 mm/sec (8 in./sec) and autolocking feature.
Measuring 8 mm in length, the new P-653 stage offers a travel range of 2 mm and submicron resolution, combined with a high holding force of 0.15 N (0.5 oz) -- advanced figures for a stage of these minute dimensions, the company said.
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 fibers, micro-optics, or microelectromechanical (MEM) elements fast and precisely. These nonmagnetic ceramic motors contain no lubricants and can also be used in medical applications.
Features & Advantages:
Motion is controlled by TTL voltage pulses applied to the driver electronics. The self-adjusting driver creates the high-frequency, nanometer-level oscillations (~500 kHz) that make the ultrasonic ceramic motor move.
- 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: Piezo motor drive is only 8-mm long
PILine linear piezomotors are based on a, patented ultrasonic drive. 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, nonmagnetic and self-locking.
