Electric motor module with integrated cam switches incorporating a single wiring connection point

A method for installing an electric motor assembly within an appliance comprising:

• 1) providing an appliance;
• 2) providing an electric motor assembly comprising:
• a motor module housed within a motor housing shell having a front cover, a cylindrical side wall and an open back side;
• a motor housing baseplate attached to the open back side of the motor housing shell;
• a motor shaft which extends through the motor housing baseplate and which engages a cam;
• at least one microswitch module which is positioned adjacent to the cam, wherein the cam engages the at least one microswitch module at a contact point upon rotation of the cam by the motor module;
• microswitch terminals which extend from the at least one microswitch module;
• and
• motor terminals which extend from the motor module through the motor housing shell;
• wherein the microswitch terminals are positioned adjacent to the motor terminals to provide a single power point connection for connecting sockets of a wiring harness;
• 3) providing a mechanical device in operable association with the electric motor assembly, wherein the mechanical device and the electric motor assembly are housed on a chassis;
• 4) inserting the chassis containing component parts of the mechanical device and the electrical motor assembly within the appliance;
• 5) connecting the mechanical device to the appliance by connecting the chassis to the appliance and the component parts of the mechanical device to the appliance;
• and
• 6) electrically connecting the electric motor assembly to the appliance by connecting sockets of an appliance wiring harness to switch terminals and motor terminals within a microswitch-electric motor connector port through a single point power connection.

An electric motor assembly comprising:

• a synchronous gear motor housed within a motor housing shell having a front cover, a side wall and an open back side;
• a motor housing baseplate attached to the open back side of the motor housing shell;
• a motor shaft defining a center axis B of the motor shaft about which it is adapted to rotate, the motor shaft, operationally engaged to the synchronous gear motor, adapted to output work therefrom, and which extends through the motor housing baseplate;
• a first cam located on and operationally engaged with the motor shaft;
• a first microswitch module selectably closable by rotation of the first cam;
• microswitch terminals which extend from the first microswitch module;
• motor terminals which extend from the synchronous gear motor through the motor housing shell;
• wherein the microswitch terminals are positioned adjacent to the motor terminals to provide a single power point connection adapted for operational engagement with an associated wiring harness socket.
