Abstract: Driver circuits for a low-cost two-phase motor are disclosed. Cost reductions may be further achieved by utilizing a printed circuit board (PCB)-based stator and methods of manufacturing, as disclosed herein. The disclosed technology can be particularly well matched for use in two-phase motors, such as axial-flux motors the utilize one or more ferrite-based rotors and a printed circuit board (PCB)-based stator. In certain implementations, part or all of the motor driver circuitry may be integrated onto the same PCB as is utilized to define the stator windings. In other implementations, the motor driver circuitry may be independently utilized with other traditional electrical motors.

Abstract: A device includes a housing configured with a working element. The device further includes a motor configured for urging motion of the working element. The device further includes a power control module. The power control module is configurable for being in electrical connection with at least one of the motor, a first power source configuration and a second power source configuration. The first power source configuration is configurable for being electrically connected to a battery assembly having a DC power output. The second power source configuration is configurable for being electrically connected to a power inverter, the power inverter configured for receiving an AC power and further configured for outputting a DC power to the second power source configuration. The motor receives power via the power control module from the first power source configuration and/or the second power source configuration.
