A system to convert electrical power to torque is disclosed where the system includes one or more motor controllers, each motor controller adapted and configured to receive power input commands and to receive high-voltage, direct-current (HVDC) input power and convert the HVDC input power to multiphase high-voltage, alternating-current (HVAC) output power, wherein each motor controller varies its respective multiphase HVAC output power in response to the power input commands received; and an electric motor assembly having a main shaft for supplying torque, the electric motor configured and adapted to receive input power as multiphase HVAC from the one or more motor controllers to rotate the main shaft. The system in an embodiment is configured as a propulsion system, wherein the shaft of the electric motor assembly is configured to supply torque to a propulsor of an aircraft.
