Abstract
A busbar may include bars, bus pins connected to the bars, connection wires, and an overmold. The overmold may support the bars, the bus pins, connection wires. The connection wires may be configured to connect the bus pins and the bars. The overmold may configured to at least partially encapsulate each of the bars, the bus pins, and the connection wires. The overmold may define holes and a pass through. A stator may include the busbar, a stator core, windings, and a stator carrier. The winding may be connected to the bus pins. An electric motor may include the stator and a rotor.
