Abstract
An apparatus includes a motor including a rotor and a coil system comprising a first set of coils, a second set of coils, and a third set of coils; and a switching mechanism that connects the first set of coils and the second set of coils to a first polarity output of a power source and connects the third set of coils to a second polarity output of the power source, wherein the switching mechanism applies energy from the power source to the coil system to move the rotor to a desirable start-up position wherein a magnetic flux generated by the rotor is positionally end directionally aligned with a magnetic flux generated by the coil system.
