This patent describes, in combination, a land vehicle having axially aligned ground engaging tractive wheels, and a drivetrain carried by the vehicle for the propulsion thereof. The drivetrain comprises: (a) a substantially fixed DC power source including at least one chemical battery, (b) transmission means including selectable multiple gear ratios, an input shaft and a mechanical differential operative to transfer torque to the wheels, (c) a single-phase self-synchronous permanent magnet motor including, (i) an elongated central shaft, (ii) a generally u-shaped frame assembly adapted for mechanical grounding the shaft to a relatively stationary portion of the vehicle, the shaft being secured to the frame proximate each end thereof, (iii) a stator assembly secured to the shaft and characterized by a plurality of outwardly directed integrally formed salient poles and associated bifilar-wound induction coils, and (iv) a rotor assembly rotatably disposed on the shaft and substantially enclosing the stator assembly, the rotor assembly comprising a cylindrical shell defining an inner surface.
