1. An electric drive system, comprising:
a magnetic rotor assembly rotatable about a rotational axis;
a first coil stator assembly, coaxially aligned with and rotatable about the rotational axis, configured to receive a first drive signal and apply a first torque to the magnetic rotor assembly in response to the first drive signal; and
a second coil stator assembly, coaxially aligned with and rotatable about the rotational axis, configured to receive a second drive signal and apply a second torque to the magnetic rotor assembly in response to the second drive signal, the second coil stator assembly being mechanically coupled to the first coil stator assembly such that motion of the first coil stator assembly is coupled to motion of the second coil stator assembly,
wherein when the first torque and the second torque are applied to the magnetic rotor assembly at the same time, the first torque and the second torque cause at least one of:
the magnetic rotor assembly to rotate about the rotational axis; or
at least the magnetic rotor assembly, the first coil stator assembly, and the second coil stator assembly to move along a defined path that is in a transverse direction relative to the rotational axis.
