QM Power will build and empirically test Space and Cryogenic qualified preproduction Parallel Magnetic Circuit [PMC] 1-5 HP motor/actuators with electronic controllers. These preproduction prototypes will demonstrate lower operating power requirements for cryogenic motor/actuator components used in Space applications. PMC is an enabling technology having a broader peak power and high efficiency range than incumbent solutions for prime mover and dynamic suspensions used in space rovers and actuation in robotic systems. The PMC motors/actuators and electronic controllers to be built and empirically tested are those identified through the extensive modeling and analysis performed during the execution of QM Power's NASA Phase I contract NNX10CD85P demonstrating power densities greater than 0.050KW/lb with efficiencies greater than 90%. These PMC motor/actuator prototypes will undergo extensive testing in cryogenic and vacuum environments measuring performance, structural integrity, space radiation tolerance, and low out gassing. The prototypes will be optimized for manufacturing production under a Phase III effort for commercialization.
