Abstract
Systems and methods are provided for an electric tool (e.g., a power tool) that includes an output driver for receiving an accessory, and an accessory-type detector. A motor of the electric tool is coupled to the output driver for driving the accessory. The power tool also includes an operation trigger for activating the motor and a motor controller. The motor controller includes an electronic processor that is coupled to the accessory-type detector, the motor, the operation trigger, and a memory. The memory stores instructions that when executed by the electronic processor cause the motor controller to detect a characteristic of the accessory from output of the accessory-type detector. The motor controller determines an operational characteristic for the accessory based on the detected characteristic, and controls operation of the motor to drive the accessory according to the operational characteristic when the operation trigger is activated.
