Motor cap assembly for reducing internal temperatures
Disclosed is an end cap for a motor housing containing an electric motor, including a tubular structure defining an interior space, including an open first end connectable to the motor casing; a second end, including a first planar surface; a second planar surface offset from the first planar surface and substantially parallel to the first planar surface; and at least one air grate surface substantially perpendicular to the first planar surface and the second planar surface, positioned between and attached to the first planar surface and the second planar surface, and wherein the at least one air grate surface includes at least one air grate configured to permit air flow into and/or out of the interior space.
1. A motor assembly having a shaft end and a motor end, comprising:
an end cap removably connectable to the motor assembly at the motor end and defining a tubular space therein, comprising:
a first an open first end connectable to the motor end;
a second end, comprising:
a first planar surface;
a second planar surface offset from the first planar surface and substantially parallel to the first planar surface; and
at least one air grate surface positioned between the first planar surface and the second planar surface and substantially perpendicular to the first planar surface and the second planar surface, the air grate surface including at least one air grate configured to permit air flow into and/or out of the interior space; and
a motor control module having a substantially semi-circular design and configured to be mounted within the tubular space of the end cap and electrically connectable to the motor to provide control to the motor,
wherein the air grate surface includes at least two air grates positioned such that as the motor rotates a directional air flow is created within the interior space generating air flow through the air grates with one air grate as an intake air grate and the other grate as an exhaust air grate.
2. The motor assembly of claim 1 , wherein the at least one air grate surface includes two air grates each positioned substantially along a different radial line of the end cap.
3. The motor assembly of claim 2 , wherein the air grate surface is one of a planar surface or an arcuate surface.
4. The motor assembly of claim 1 , further comprising:
circuit board mountings positioned within the interior space configured to attach a circuit board thereto; and
end cap mountings positioned to attach the end cap to the electric motor.
5. The motor assembly of claim 1 , wherein the air grates are each positioned substantially parallel to radial lines of the end cap.
6. The motor assembly of claim 1 , wherein the air grate surface defines at least one switch receptacle configured to mount a control switch therein.
7. The motor assembly of claim 1 , wherein the at least one air grate surface includes two air grates each positioned substantially along a different radial line of the end cap.
8. The motor assembly of claim 2 , wherein the air grate surface is one of a planar surface or an arcuate surface.
9. The motor assembly of claim 1 , further comprising:
circuit board mountings positioned within the interior space configured to attach a circuit board thereto; and
end cap mountings positioned to attach the end cap to the electric motor.
10. The motor assembly of claim 1 , wherein the air grates are each positioned substantially parallel to radial lines of the end cap.
11. A motor assembly having a shaft end and a motor end, comprising:
