    Abstract: A resistor and stall protection assembly for a permanent magnet brush-type DC motor includes a first speed circuit for operating the motor at a first speed. The first speed circuit includes at least one resistor 12 for reducing voltage to the motor 14. A second speed circuit is provided for operating the motor at a speed greater than the first speed. A first connecting structure 16 is constructed and arranged to connect the assembly to a source of power 18. A second connecting structure 20 is constructed and arranged to connect the assembly to the motor 14. A sensing structure 22 is constructed and arranged to sense a motor stall condition, and a circuit protecting device 24 such as a relay or transistor is constructed and arranged to interrupt power to the motor 14 when the motor is in the stall condition.
