Abstract:
An electric motor controllable by a controller, the controller configured to provide a first power or a second power, the electric motor comprising:a housing; a first stator fixed relative to the housing and adapted to receive the first power, the first stator producing a first magnetic field when the first stator receives the first power, wherein the first stator includes a first number of poles; a second stator fixed relative to the housing and adapted to receive the second power, the second stator producing a second magnetic field when the second stator receives the second power, wherein the second stator includes a second number of poles, and wherein the first number is greater than the second number; and a rotor including a shaft rotatable relative to the housing, a first rotating member connected to the shaft for rotation therewith and adapted to interact with the first magnetic field, and a second rotating member connected to the shaft for rotation therewith and adapted to interact with the second magnetic field, the rotor rotating at a first speed when the first magnetic field interacts with the first rotating member and rotating at a second speed when the second magnetic field interacts with the second rotating member.
