Specifications include; >30 mN.m torque (>40 mN.m holding torque), min angular step 196 µrad, max speed >100 rpm, dynamic range 4kHz, weighs 77 g.


The PM-1124R-HS-E linear piezo motor represents a quantum leap in design of small high-performance DC motors. Injection-molded using extremely durable, but light weight engineered reinforced thermoplastics, the PM-1124R-HS-E provides low cost with superior precision and ultra fast response/start-stop characteristics. Highly energy efficient, the PM-1124R-HS-E consumes zero power in hold position while still providing significant torque. Available in a variety of configurations (including non-magnetic) the PM-1124R-HS-E is the ideal choice for high volume demanding OEM applications where superior performance and economical unit cost are important factors. Close loop control of the motor is achieved via an optical encoder mounted on the back of the motor. This provides 196 µrad close loop resolution. Encoder communication electronics consist of a daughter board (pcb) mounted on the main driver board. The encoder electronics includes a serial (RS-232) port. Optional PLC software/GUI enables control of the motor using Windows®10 or earlier.
