In various embodiments, the present disclosure provides a speed control system for a motor that includes a fixed speed control portion and a variable speed control portion. The fixed speed control portion is operable to control a speed of a motor in a fixed speed mode wherein the motor is operated at a preselected fixed speed below a predetermined fixed speed mode threshold speed. The variable speed control portion is operable to control the motor in a variable speed mode wherein the motor is operated such that a speed of the motor can be selectively varied within a range between the fixed speed mode threshold speed and a maximum motor speed. The system additionally includes a switching device structured and operable to selectively switch the speed control system between the fixed speed mode and the variable speed mode.
