Johnson Electric has came up with revolutionary piezo motors for use in defense applications that need backlash-free, silent free operation. The ER series of the Nanomotion brand highlights the benefits of using piezo motion technology packaged in the tubular motor housing. The ER motor offers high-precision, robust design with integrated encoder and driver.
The motor will direct the drive and eliminate the need for gears with zero backlash performance. The power efficiency is maximized because of built-in braking that can hold position without extreme power consumption. The ER motor series also is known for having the best SWaP or size, weight and power performance, for auto focus mechanisms and shutter control used by hand-held, heat-mounted or in-flight devices.
