1. A fan motor controller housing comprising:
- an inner fan housing;
an outer fan housing, the outer fan housing including a base plate, at least one plenum, and air passages;
a plurality of stator vanes;
a motor control housing, the inner fan housing, the outer fan housing, the stator vanes, and the motor control housing made of a polymer;
at least one heat sink, the heat sink attached to the at least one wall of the at least one plenum, the air passages configured to direct air flow within the outer fan housing to the at least one heat sink of the plenums; and
at least one motor control component, the motor control component attached to the heat sink.

Abstract
An example fan motor controller housing includes an inner fan housing, an outer fan housing including a base plate, plenums and air passages, stator vanes and a motor control housing. The inner fan housing, the outer fan housing, the stator vanes, and the motor control component housing are all made of a polymer. The fan motor controller housing also includes heat sinks attached to the plenums. The heat sinks are cooled by air flowing from air passages through the plenum. Motor controller components are attached to the heat sink and heat dissipates from the motor controller components to the heat sink.

13. A fan motor controller housing comprising:
-
an inner fan housing; an outer fan housing, the outer fan housing including a base plate, at least two plenums, and air passages to connect the plenums; a plurality of stator vanes; a motor control housing, the inner fan housing, the outer fan housing, the stator vanes, and the motor control housing made of a polymer; at least one heat sink, the heat sink attached to at least one wall of a first plenum and cooled by impingement, the air passages configured to direct air flow within the outer fan housing directly to the heat sink; at least one inductor enclosed by a top wall of a second plenum, the air passages directing air flow from the first plenum over the inductor in the second plenum; and at least one motor control component, the motor control component attached to the heat sink. - View Dependent Claims (14, 15, 16, 17)
