A motor assembly is provided including a stator and a rotor. The stator includes a stator main body defining a longitudinal axis, stator teeth projecting radially from the stator main body, stator windings wound around the stator teeth, and two winding terminals provided for each stator tooth extending away from the stator main body substantially parallel to the longitudinal axis. A circuit board is oriented along a radial plane adjacent the stator. The circuit board includes a central through-hole through which a rotor shaft extends, at least one magnetic sensor mounted on a surface of the circuit board around the central through-hole configured to magnetically interface with the rotor, peripheral openings arranged to receive the winding terminals of the stator, and conductive routings extending from the peripheral openings to connect the stator windings in a series or a parallel configuration and/or a wye or a delta configuration.

A cutting tool attachment for a power tool is freely rotatable about an end of the power tool. A fence provides a complementary flat surface area for the cutting tool attachment to rest against a surface of the material to be cut. The fence prevents free rotation of the cutting tool ttachment while in use. A handle allows a user to guide the attachment along the surface of the material, while also providing leverage to keep the attachment against the material surface close to the attachment, but at a safe position to reduce the chance of injury. A user can rotate the power tool relative to the cutting attachment to achieve a comfortable position or to help turn the attachment and power tool. The power tool is therefore positionable along a 360 arc of movement relative to the attachment while the attachment is positioned along the surface of a material.

The disclosure provides a grey hair removal component, and a grey hair removal comb and a grey hair removal system composed of several grey hair removal components. The grey hair removal component includes at least one housing, and at least one identification unit and a grey hair removal unit arranged within the housing (0), and further includes a sensing unit arranged at an end of the housing, and the sensing unit responds to the contact of the component with a scalp and outputs a start signal; the identification unit identifies a grey hair in response to the start signal and outputs a removal signal; and the grey hair removal unit removes the identified grey hair based on the removal signal. By means of using the grey hair removal component and the grey hair removal system to scan the surface of the entire scalp (9), the aims of removing all grey hair and leaving colored hair can be achieved, and enhancing the personal appearance of a user.

A motor-operated shears which includes two blades that can move towards each other to perform a shearing movement is provided. In order to advantageously improve functional safety, towards the end of the movement, the blades are acted upon in a direction running transversely to the movement so as to keep the blades at a distance from one another in said direction.

The present application discloses a blade mechanism and an electric scissors having the blade mechanism. The blade mechanism includes a setting blade, a moving blade, and a rotating shaft assembly. The rotating shaft assembly respectively passes through the setting blade and the moving blade to allow the setting blade and the moving blade being rotatablely connected. The cutting edge of the moving blade is automatically ground when the moving blade frictionally rotates relative to the setting blade. According to the present application, the moving blade and the setting blade of the blade mechanism open or close to generate friction, allowing the cutting edge of the moving blade to be automatically ground by the setting blade, thus the durability of the moving blade is improved.
