The SPS20 series uses a screw construction in the front
shaft, creating an actuator for converting rotational force
into linear force. The shaft extends as it rotates, and there is
steel ball on the end for pushing the object. The motor is a
normal PM stepping motor and can be driven with a
standard stepping motor driver. The characteristics assume
intermittent driving. Power consumption during continuous
operation is about 1 W (without heat sink), 5 W (B5 1 mm
steel plate attached).
