Abstract: A magnetically de-coupled, separately controlled, electric machine assembly including a radial and one or more axial electric machines, each with rotors mechanically coupled to and arranged to directly drive a single shaft. Each of the electric machines are independently, but cooperatively, controlled by an inverter unit that includes one or more inverters. The axial and radial electric machines are contained in a single housing.

Abstract: A method of predicting torque modulation parameters of an electric machine based on operating conditions of the electric machine includes generating a data set for torque modulation parameters of an electric machine for the different operating conditions of the electric machine. The method also includes relating the torque modulation parameters to the operating conditions of the electric machine with a model and loading the model into a controller of the electric machine. The method also includes predicting the torque modulation parameters of the electric machine for the operating conditions of the electric machine using the model in real-time. The method may include adjusting the torque modulation parameters of the electric machine based on the predicted torque modulation parameters.

Abstract: A magnetically de-coupled, separately controlled, electric machine assembly including a radial and one or more axial electric machines, each with rotors mechanically coupled to and arranged to directly drive a single shaft. Each of the electric machines are independently, but cooperatively, controlled by two (or more) inverters respectively. The axial and radial electric machines are contained in a single housing.
