Electric fan motor assembly
View Patent ↗A fan assembly is disclosed. The fan assembly has a frame and a motorized blade assembly. The motorized blade assembly has an electric motor and an integrally attached bladed propeller with a central hub. The motor includes a rotor and a stator, the rotor having a rotatable output shaft extending from a front side of the motor with a bladed propeller secured to the output shaft. The motor includes a housing with a mounting area for securing an electrical control switch. The mounting area is provided by a flange portion of the rear motor wall and positioned radially outwardly relative to the output shaft, and provides mounting of the control switch with a user interface that is exposed from the fan frame. The fan assembly motor also may provide an electrical connection port for removable attachment of an electrical power cord, wherein the connection port is integral with the motor housing and is exposed from the fan frame for attachment of the cord by a user.
1. An electric motor for incorporation into a fan assembly, the motor comprising:
a rotor including a rotatable output shaft;
a stator including a core of stacked laminations and windings, the laminations defining a supporting portion;
a housing covering at least a portion of the rotor and stator, the housing engaging the supporting portion and having an electrical control switch attached directly thereto for controlling the operation of the motor the control switch having a user interface portion adapted to be exposed from the fan assembly in a direction generally parallel to the output shaft and for manipulation by a user; and
an electrical input port directly attached to the housing for receiving an electrical cord for connecting a source of electrical power to the motor.
2. An electric fan assembly comprising:
a frame;
an electric motor having a rotor including a rotatable output shaft, a stator including a core of stacked laminations defining a supporting portion and a housing engaging the supporting portion with a control switch directly attached to the housing, the control switch having a user interface portion protruding outwardly from the frame in a direction generally parallel with the output shaft; and
an electrical input port directly attached to the housing, the port protruding outwardly from the frame for operably connecting a source of electrical power to the motor.
3. An electric motor comprising:
a housing engaging a supporting portion defined by a core of stacked laminations and rotatably supporting a rotor including a rotatable output shaft;
a control switch directly attached to the housing and having a user interface portion extending away from the housing and oriented generally parallel to the rotatable output shaft; and
an electrical input port directly attached to the housing, the port protruding outwardly from the frame for releasably connecting a source of electrical power to the motor.
