Electric motor
View Patent ↗An electric motor is described in which a first magnet wire forms a first pole of the coil, is disposed across two terminals of a fuse, and terminates at a first end on a power switch. The portion of the first magnet wire between the terminals of the fuse is severed such that all current of the motor must travel through the conductor of the fuse. The second end of the first magnet wire terminates at dual tang terminal disposed on the brush housing.
1. A method of making an electric motor, comprising:
winding a first magnet wire about a first lug in a winding board and a first protrusion in a stator, the winding board being disposed on the stator and including a switch having at least an internal terminal, and a fuse having an input terminal and an exit terminal;
laying the first magnet wire across the exit terminal and the input terminal on the fuse;
connecting an end portion of the first magnet wire directly to the switch; and
severing the first magnet wire between the input terminal and the exit terminal on the fuse.
2. The method of claim 1 , further comprising routing the first magnet wire along the winding board under clips.
3. The method of claim 1 , wherein the switch includes an internal terminal and an external terminal, the internal terminal includes a first block and a second block, and the first magnet wire is terminated on the first block.
4. The method of claim 3 , wherein the first block and the second block include tang terminals and the first magnet wire is fused to the tang of the first block by welding.
5. The method of claim 1 , wherein the input terminal and the exit terminal include tangs, and the first magnet wire is fused to the tangs by welding.
6. The method of claim 1 , further comprising winding the first magnet wire about the first lug in the winding board and the first protrusion in the stator to form a first pole.
7. The method of claim 1 , further comprising winding a second magnet wire about a second lug in the winding board and a second protrusion in the stator to form a second pole.
8. The method of claim 7 , further comprising disposing the end of the second magnet wire on the second block of the internal terminal.
9. The method of claim 8 , further comprising fusing the second magnet wire to the tang of the second block by welding.
