Abstract
An anti-sparking method for a power tool includes the following steps: (1) turning on a controlling switch, which causes a motor to rotate, and a MCU module to record a first operation state of the motor; (2) turning off the controlling switch which causes the motor begin to stop rotating and the MCU module to record a time duration from a time point of the motor being begun to stop rotating to a time point of the motor completely stopped rotating as t1; (3) turning on the controlling switch again, which causes the MCU module to record a second operation state of the motor. When the first and second operation states are different, the MCU module controls the power module to supply power to the motor driving module after a delay time duration, which is longer than t1. A control device and a computer readable storage medium are also provided.
