ROMO series piezo rotary motor with a plain hollow shaft and magnetic encoder.
Piezo Motor Company’s new range of miniature piezomotors sets new benchmarks for compact, high-performance rotary and linear piezoelectric actuators/motors. We’ve combined lightweight design with superior precision and functionality.
These piezomotors are exceptionally energy-efficient, requiring no power in the hold position while still maintaining full torque and force. This efficiency makes them ideal for demanding OEM applications where performance and cost-effectiveness are paramount.
Designed to operate at low voltage (5.0 VDC to 7.5 VDC) and small currents (e.g., 30 mA), the new PMC piezomotors are available with optional factory-installed encoders and boast several distinctive features:
