The present invention is a brushless electric motor that can be used in high performance applications, such as model airplanes. The rotor assembly, which includes the rotor shaft, encloses a winding core, which is part of a fixed stator assembly. Conducting wire in the armature portion of the stator assembly is wrapped around a set of spokes, extending radially from an inner hub. The spokes are formed from a stack of flat metal laminations, the laminations oriented perpendicular to the rotation axis. The spokes are wrapped with a single layer of copper wire, which is connected to the energy source when the motor is operational. These spokes are long relative to the diameter of the inner hub, leaving V-shaped slots through the winding core. Openings in both end bells allow air to freely flow into the core, cooling the single layer of conducting wire. Using a wedge to force the wire against the spokes during varnishing results in close contact between the wire and the conducting material in the winding core. When the motor is operational, this contact causes the winding core to act as a heat sink, allowing a relatively heavy motor to sustain high power without damage.
