Embodiments of the disclosure provide a magnetically geared DC brushless motor and method of using the same. The motor may use multiple separately terminable winding sections wrapped around motor armatures. At least one of the separately terminable winding sections may have windings around adjacent armatures. The motor may be configured to activate certain winding sections to control the velocity and torque outputs of the motor. The winding sections may include copper wire, and the separate winding sections may have wires of different gauge sizes. Various winding sections may be powered by separate voltage sources. Various winding sections may be powered by separate pulse-width modulation voltage sources. The motor may be configured to increase and/or decrease the voltage of a winding section or combination of sections to prepare for the activation or deactivation of another winding section or combination of winding sections.
