摘要： A permanent magnet type rotating electrical machine characterized by reduced vibration and noise, or improved efficiency. In a permanent magnet type rotating electrical machine comprising a stator 10 provided with concentrated winding and a rotor with permanent magnets 24 embedded in the rotor core 21, induced voltage waveform is improved by formation of two grooves or holes (flux barriers) extending in the axial direction for each magnetic pole on the bridge 25 of the core between the permanent magnet insertion hole 23 and the outer surface of rotor 20 in such a way that they are placed at an equally spaced interval over the entire circumference of the rotor 20.

摘要： It is an object of the present teachings to provide a technique that rationalizes the structure of the brushless motor so as to save space in the power tool. According to the present teachings, a representative brushless motor utilized in a power tool may comprise a stator, a rotor and a cooling fan. The brushless motor is disposed within the power tool. The brushless motor is adapted to supply driving current to the stator to drive a tool bit of the power tool by rotating the rotor. The cooling fan is molded of a magnetic or conductive material so that the cooling fan also serves as a rotating position detector that detects the rotating position of the rotor with respect to the stator. Because the cooling fan may also have a function of rotating position detector of the rotor, the inner space of the power tool can be rationalized.
