A homopolar electrical machine includes a stator having a stationary magnetic core and multiple stator windings disposed within the stationary magnetic core. A rotor includes a first set of pole pieces at a first end of a shaft and a second set of pole pieces at a second end of the shaft. The pole pieces are separated by air gaps. The rotor is a one-piece structure having only the shaft, the first set of pole pieces, and the second set of pole pieces integrally formed from a single material. A stationary field coil is coupled to the stator. The stationary field coil includes a cryostat configured to cool the stationary field coil to superconducting temperatures. The stationary field coil has a coil diameter that is at least partially greater than an outer diameter of the rotor. Each stator winding is unitarily formed as a single structure that extends along a length of the homopolar electrical machine beyond the first and second sets of pole pieces and is disposed within an air gap of the homopolar electrical machine.
