Abstract
An electric power apparatus includes a main planar body having a circular opening that supports a brushless direct-current (BLDC) motor. The motor includes a stator, a rotor, a motor spindle extending through the circular opening, a first end cap formed on a first side of the stator and mounted on the main planar body; and a second end cap formed on a second side of the stator and secured to the first end cap to form a substantially airtight sealed compartment around the stator and the rotor. The rotor includes a series of openings in a radial wall that generates an airflow circulating through the sealed compartment to transfer heat from the stator to the first end cap and the second end cap.
