Systems and methods of detecting an overload condition. In one embodiment, a method of monitoring a load of a DC motor includes intermittently de-energizing the motor; monitoring a first voltage; and measuring a first interval of time between a starting time and an ending time, wherein the starting time comprises the time at which the motor is de-energized and the ending time comprises a time at which the first voltage and a reference voltage have substantially similar values. |
