Abstract
An electromagnetic actuator is provided. The electromagnetic actuator includes a planetary roller screw and at least two motor assemblies disposed on opposing sides of the roller screw. The planetary roller screw includes a shaft linearly translatable between an extended position and a retracted position, a nut rotatable about the shaft, and a plurality of rollers coupling the nut to the shaft. A spur gear is fixedly connected to the nut. Each motor assembly includes a DC motor having an output shaft, a planetary gear head coupled to the DC motor output shaft and having an output shaft, and a pinion gear coupled to the spur gear and fixedly connected to the planetary gear head output shaft.
