Rotary Piezomotors

DTI’s rotary piezo motors represent a quantum leap in design of small size high-performance DC motors. Injection-molded using extremely durable, but light weight engineered reinforced thermoplastics, they combine economical cost with superior precision and ultrafast response/start-stop characteristics. Highly energy efficient, DTI’s rotary motors consume zero power in hold position while still providing significant torque.


DTI’s rotary motors 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 optical 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.
