Abstract
A transverse flux electric motor includes a stator including coils configured to carry current and a rotor arranged to interact with the stator. The rotor is configured to produce a torque for driving rotation of the rotor. The transverse flux electric motor has an active parts mass, m, equal to a cumulated mass of components of the transverse flux electric motor that contribute to the production of the torque. The transverse flux electric motor has an active parts torque density, ρ, defined as a peak rated torque, τ, divided by the active parts mass, m. The transverse flux electric motor has a power factor equal to cos(∅), wherein ∅ is a steady-state phase difference between a stator coil current and a stator coil voltage, and wherein the transverse flux electric motor has a machine parameter Δ that is greater than or equal to 65 Nmkg, where Δ equals ρ/cos(∅).
