Abstract:
1. A device, comprising: a housing configured with a working element; a motor configured for urging motion of the working element, the motor having a first coil and a second coil, both of the first coil and the second coil being wrapped on an armature of the motor; a first brush configured for being in electrical contact with a first commutator, the first commutator configured for being electrically connected to the first coil; a second brush configured for being in electrical contact with a second commutator, the second commutator configured for being electrically connected to the second coil; a hybrid controller configured for receiving electrical power from at least one of a first voltage configuration and a second voltage configuration, and delivering said electrical power to at least one of the first brush and the second brush, wherein the hybrid controller includes a first circuit setting and a second circuit setting, the hybrid controller configured for electrically connecting the first brush and the second brush in a parallel configuration when the hybrid controller is established at the first circuit setting, the hybrid controller further configured for electrically connecting the first brush and the second brush in a series configuration when the hybrid controller is established at the second circuit setting; wherein the hybrid controller includes a boost setting in which electrical power simultaneously received from both of the first voltage configuration and second voltage configuration is delivered to the first brush and second brush at the second circuit setting.
