Electric motors play an important role in today's society, from powering household appliances like blenders to industrial equipment like trains. It seems almost impossible not to use an electric motor in our daily lives. In the comfort of our home, electric motors drive fans, refrigerators, and air conditioners, just to name a few. Researchers are constantly looking for new ways to incorporate electric motors into our lives. Electric motors work by converting electrical energy into mechanical energy using energy stored in the magnetic field (Sarma, 1981). Mechanical energy (torque) is produced when opposing magnetic fields attempt to align. Therefore, the centerline of the north pole of one magnetic field is directly opposite the centerline of the south pole of another magnetic field (Fitzgerald et al., 1981). The opposing magnetic fields in a motor are generated by two separate concentrically oriented components, the stator and a rotor (Figure 2-5). Figure 2 5 Rotor and Stator Schematics of a Three Phase DC Motor The stator is the stationary component while the rotor is the rotational component of the motor. Magnetic fields are usually created when an electric current is applied to a series of conductive wires coiled together (Dixon, 2001). Magnetic fields can also be created using permanent magnets (PMs). Electric motors can also function as electric generators (Correla, 1986). Electric generators are devices that can convert mechanical energy into electrical energy. An example would be a wind turbine that works like an electrical generator. It converts the mechanical energy of the rotating shaft caused by the wind into electrical energy (Correla, 1986). The focus of this research will be... halfway through the document... a patent, is the embedding of copper filaments in parts manufactured with FDM technology. To embed the copper filament into the thermoplastic substrate, 20kHz ultrasonic energy and a 500W power supply (equipped with a 12.7mm exponential horn) was installed to enable feeding a wire along a central axis (Espalin et al, 2013) An alternative method for fabricating cavities and channels was to use a YAG laser microwelding system (model LW5AG, Miyachi Unitek, Monrovia, CA). This process produces solderless joints between the filament and the electronic component. Espalin et al., (2013), Shemelya et al., (2013) and Aguilera et al., (2013) use this embedding method to produce a probe touch sensor and a functional three-phase DC motor, respectively. The three-phase DC motor discussed in the remainder of this thesis is a continuation of the work of Aguilera et al. (2013).
