/Multi-speed Power Tool With Electronic Clutch
Abstract

A power tool and a method of operating a power tool including a motor, a clutch collar including a plurality of settings, a wireless transceiver operable to form a wireless connection with a remote device, and a processor coupled to the clutch collar and the wireless transceiver. The processor receives, via the wireless transceiver, a mapping including a plurality of torque levels corresponding to the plurality of settings. The processor detects that the clutch collar is set to a setting of the plurality of settings. The processor determines the torque level for the setting from the mapping and detects, during the operation of the power tool, that a torque of the power tool exceeds the torque level. The processor is also configured to generate an indication that the torque exceeds the torque level. The indication may include flashing a light, ratcheting the motor, and stopping the motor.
