GVCM 032-076-02M (metric version) linear, voice-coil servomotor features a 63.5 mm (2.50 inch) stroke and 31.8 mm (1.250 inch) diameter, and achieves high accuracy and repeatability when coupled with a linear encoder in a servo-position loop. This low inertia motor, also known as an electric cylinder and moving coil motor, is reported to provide high reliability, high speed, zero cogging and high acceleration/deceleration. It also has a high force-to-size ratio of 8.0 N (1.8 pounds) continuous force and 25.3 N (5.3) of peak force at 10% duty cycle.
GVCM’s internal M2.2 x 0.45 x 0.20 threaded 0.175 ± 0.008 mm (0.125 ± 0.0003 inch) diameter shaft enables a zero-backlash connection to the load. Two M3.5 x 0.6 x 0.20 threaded mounting holes on 12.7 mm (0.500 inch) bolt circles on either end of the motor allow easy integration into applications. This compact, linear actuator’s overall length is 152.4 mm (6.00 inches), while the shaft in the extended position extends 66.7 mm (2.625 inches) beyond the housing. The shaft is guided by a plain bushing that tolerates a side load up to 2.0 N (7.2 oz).
