Piezo Motors
New and innovative piezo motors (in rotary or linear format) from Piezo Motor Company in USA have recently been added into Motion Control Products' product portfolios, representing a quantum leap in design of small size high-performance DC motors.
Piezo Motion's rotary or linear piezomotors work on a patented principle of excitation of ultrasonic standing waves within a piezoelectric resonator. The resulting superposition of two orthogonal ultrasonic waves causes eliptical movement of the resonator tip, which direct drives a rotary or linear element.
Being injection-molded using extremely durable, but light-weight engineered reinforced thermoplastics, our piezo motors combine economical cost with superior precision and ultra-fast response /start-stop (≈ 30µs) characteristics. Piezo Motion’s rotary or linear piezomotors are highly energy-efficient, consuming zero power in hold position while still providing significant torque or force.
Our piezomotors are available as both open-loop control (non-feedback control) and closed-loop control (feedback control) systems; and are offered in a variety of configurations (including non-magnetic).
In the closed-loop system, motion control of the piezo motor is achieved via feedback generated from an encoder integrated within the motor assembly. Encoder communication electronics consists of a daughter board (pcb) with a serial (RS-232) port, mounted onto the main driver board. Optional programmable logic control (PLC) software with graphical user interface (GUI) enables control of the motor using standard Windows OS.
