资源简介：
The present disclosure discloses a power tool， including: a functional element for realizing a function of the power tool; a motor operably connected with the functional element and configured to output power to drive the functional element to work， the motor having a rotor， a stator and stator windings; a drive circuit electrically connected to the motor for driving the motor to output power; and a controller electrically connected to the drive circuit for outputting control signals to control the drive circuit; wherein the controller is configured to， based on a sampled current of the motor， output control signals that change with the change of a position of the rotor to control the drive circuit such that an input voltage and/or a current of the motor changes approximately in a sine wave. The present disclosure also discloses a control method of the aforementioned power tool.
