Custom piezo motors offer higher force, higher resolution, longer travel and more

New Scale also creates custom piezo motor systems with higher push force, higher resolution and longer travel than our smallest SQL-RV-1.8 motors. Our development team will help you create the motion system that's right for your application, navigating the tradeoffs in motor size, speed, force and power use.

Like all SQUIGGLE motors, these custom piezo motors offer greater power efficiency, higher reliability, and ten times better precision than electromagnetic motors.

Features include:

*Piezoelectric motors do not generate magnetic fields in operation. They do contain ferromagnetic materials. We can create custom motors using only non-ferrous materials as part of an OEM development project.

Examples

Below are typical performance data for a custom 7 mm diameter linear piezoelectric SQUIGGLE motor with stall force of 2 Newtons, and a larger custom motor with stall force of >5 Newtons.

Parameter 7 mm dia motor 12 mm dia motor
Travel Range up to 20 mm up to 50mm
Housing Dimensions ø 6.83 x 11.02 mm ø 12.3 mm x 36.6 mm
Motor Body Dimensions 3.4 x 3.4 x 10 mm  n/a
Resolution 0.5 μm 20 nm (without encoder)
Stall Force 200 gram force (2 N) > 5 N
Speed 4 mm/s  @ 1/2 stall force from 0.001 to 2 mm/s
Start/stop time   0.2 ms
Input Power to motor (moving) ¹ 1000 mW typical  
Input Power to controller (moving)¹ ~2.5 W max (MC-1100 controller)  
Input Power (stationary) OFF POWER HOLD 
(0 mW, 0 V to hold position)
OFF POWER HOLD 
(0 mW, 0 V to hold position)
Operating Temperature -30 to +80°C -20 to +40°C
Storage Temperature -40 to +85°C  
Shock Resistance 2500 G's  
Lifetime (load-dependent)² > 70,000 cycles  
Motor Controller MC-1100 drive card SQ-2300 controller
Operating Frequency ~ 115 KHz

¹ Power (moving) depends on motor speed and load.
² Lifetime test at continuous operation, full speed, room temperature, with 100 gram force load.

 

Performance depends on operating conditions and motor controller used. New Scale works with OEM customers to develop fully-integrated motion solutions that meet the system requirements. Please contact us to discuss your motion system requirements.
