Abstract
A electric power tool, comprising a control system electrically coupled to a power supply and a motor to supply current to the motor, where the motor may be coupled to a driven element of a tool so as to drive the driven element. The control system may have a continuous power mode and a boost power mode to supply current to the motor at a greater amount than in continuous power mode, and may be configured to switch between the continuous power mode and the boost power mode based upon a sensed load on the electric motor. In some embodiments, the control system may switch to a cutback power mode to supply current to the motor at a lower amount than in continuous power mode is the load does not decrease before a predetermined time elapses.
