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:

• Constructed from modern, reinforced engineered thermoplastics for reliability and affordability.
• Unmatched precision and resolution.
• Ultra-fast response times and exceptional start-stop capabilities.
• High torque relative to size, optimized for direct-drive applications.
• Support for stepping and continuous modes of operation.
• A speed dynamic range spanning six orders of magnitude.
• Silent operation in continuous mode and a low voltage design to minimize electrical arcing.
