  • Publication number: 20250080023
    Abstract: A power tool includes a functional piece; an electric motor; a power supply device for supplying power to the electric motor; a parameter detection device configured to acquire multiple operating parameters of the electric motor and/or the power supply device; and a controller connected to the parameter detection device and configured to control running of the electric motor. The controller is configured to detect whether the multiple operating parameters satisfy policy switching conditions corresponding to the multiple operating parameters; in the case where any operating parameter of the multiple operating parameters satisfies a policy switching condition corresponding to the any operating parameter, control the electric motor by using a first electric motor control policy; and in the case where none of the multiple operating parameters satisfy the policy switching conditions corresponding to the multiple operating parameters, control the electric motor by using a second electric motor control policy.

  • Publication number: 20230411670
    Abstract: The present application provides a pole piece forming apparatus, which may include an incoming structure, a slitter, a plurality of winders and a wrinkle remover. The incoming structure may provide a master pole piece. The slitter may slit the master pole piece into a plurality of pole pieces. The winders may pull the transport of the pole pieces, respective winding devices may wind one corresponding pole piece, and the slitter may be disposed between the incoming structure and the winders. The wrinkle remover may be arranged between the slitter and the winders. The wrinkle remover may include a first roller and a second roller that may be provided opposite to each other, the first roller may include a first rolling part, and the first rolling part and the second roller may be used for rolling an edge of a slitting edge of the pole piece.
