Abstract:
A high speed electric motor for use in a variety of applications. The electric motor an electric motor including a motor housing or stator, a rotor having a commutator and brushes for contacting the commutator at a predefined area known as the contact area. Additionally, the motor includes a forced air cooling assembly. The forced air cooling assembly includes a centrifugal fan for creating air flow, a manifold for accelerating the air flow. The manifold having exit ports and the exit ports being positioned directly over the contact area for directing the accelerated air flow at the contact area and the motor housing having at least one opening aligned with the contact area and at least a second opening defining an exit vent. Additionally, a method of cooling the motor in accordance with the invention is also disclosed.
