A manufacturer of motion simulator machines wanted to replace an existing hydraulic system with an electric actuator to simulate vibrations (frequencies from 30-50 Hz) and other disturbances experienced in real world situations in aerospace and defense applications. Although the hydraulics could achieve the aggressive high frequency moves, the hydraulic system tended to leak, require regular maintenance and could be too loud in the training environment. Additionally, the manufacturer required an electric actuator solution without the use of external cooling systems such as water or oil to remove heat from the actuator.
