Systems and methods are described for improving the performance of electric motors which employ commutators and brushes. A method includes improving the performance of an electric motor that employs a commutator and brushes comprising: sending power to the motor, reading a set of data from the motor using an analog to digital converter and a microcontroller configured to execute digital signal processing software, setting a speed for the motor, and maintaining the speed for the motor based on the set of data as analyzed by the microcontroller. An apparatus includes a current sensing device coupled in series to the motor to monitor the current of the motor, a solid state switch coupled through the microcontroller to the current sensing device which controls the amount of current delivered to the motor, a high pass filter coupled to the current sensing device that removes the 60 Hz frequency component from the voltage of the current sensing device, an analog to digital converter that sends digital output to the microcontroller, and a microcontroller to perform digital signal processing coupled to the solid state switch.
