Abstract
An actuator includes a first rotary motor, a second rotary motor, and a transmission coupled to the first and second rotary motors. The transmission converts rotation of the first rotary motor in a first direction and simultaneous rotation of the second rotary motor in a second direction to linear motion of an output shaft in a single direction. The actuator is usable in an active automobile suspension.
