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.
OPEN OR CLOSED LOOP CONTROL
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.
