Silent Piezo Motors

Silent Piezo Motors

Johnson Electric provides revolutionary piezo motor technologies for defense applications that require silent and backlash free operation. The Nanomotion brand ER series leverages the advantages of piezo motion technology packaged in a tubular motor housing. The ER motor is a robust and high precision design with integrated drive and encoder. The Piezo Rotary Motor direct drive eliminates gears to deliver zero backlash performance. Power efficiency is maximized due to built in braking to hold position without power consumption. The ER motor series has the best SWaP (size, weight and power) performance for customized applications in shutter control and auto focus mechanisms for in-flight, head mounted or hand held devices. Closed loop operation is supported by Nanomotion’s S775 XCD closed loop drive and control module, supplied as a PCBA or components for system integration.
