A strain relief plug to restrict movement of wires on a printed circuit board, the strain relief plug having an elongated stem along a vertical axis of the strain relief plug. The strain relief plug has an in-board flange defined by the elongated stem, the in-board flange configured to seat in a bore defined by the printed circuit board. The strain relief plug has an anchor defined by a first end of the elongated stem configured to prevent the strain relief plug from releasing from the printed circuit board. The strain relief plug has a bar defined by a second end of the elongated stem and transverse the vertical axis, the bar forming wire channels. The strain relief plug provides strain relief for wires on the printed circuit board of an electric motor in a vertical dimension resembling the thickness of the printed circuit board.

Strain relief plug for lead wires on a printed circuit board

The present invention provides a highly optimized motor design enabling an increase in torque compared to a similarly sized motor of traditional design. Additionally, the present invention enables motors that provide smooth, ripple free, operation at low speeds. These advances are provided through disclosure of slot/pole ratios that provide the stated benefits.
