An electrical machine includes a fan guard having a first air flow channel. A stator assembly is coupled to the fan guard and includes a stator yoke having a cylindrical outer surface and a stator pole shoe. The stator pole shoe includes a plurality of stator poles coupled to the stator yoke. The stator assembly includes a second air flow channel defined between the stator yoke and an adjacent pair of the stator poles. A rotor assembly is positioned inside the stator assembly. The rotor assembly includes a rotatable shaft and a rotor. The rotatable shaft defines a rotation axis. A control electronics board includes a plurality of heat making components and is enclosed in a housing having a vented base and a closure. The housing is coupled to the stator assembly opposite the fan guard. The vented base includes a plurality of vent openings opened toward the fan guard.
