Abstract: The present invention relates to a brushless motor, and an objective of the present invention is to provide a brushless motor which can significantly reduce the cogging torque and torque ripple of the motor by minimizing the rate of change of magnetoresistance in accordance with a change in position of a rotor through the optimization of the shape design of the rotor and a stator, and can also reduce the weight of the brushless motor through the optimization of the shape design taking into consideration the materials of the rotor and the stator.

Abstract: The present invention relates to a BLDC motor integrated with an inverter, having a motor and an inverter part that are integrally formed, and to a BLDC motor integrated with an inverter, having an improved arrangement of switching elements mounted on a PCB substrate of an inverter part and three phase terminals of a stator coil such that the inverter part including the PCB substrate can be compactly formed.

Abstract: Disclosed is a BLDC motor, including: a stator which is provided with a plurality of teeth extending toward an inner side of a core and pole shoes each extending to be formed at radial inner end parts of the teeth; and rotors which are disposed at an inner side of the stator surrounded by the pole shoes while being spaced apart from the stator and have a plurality of permanent magnets coupled to cores thereof. Inner circumferential surfaces of the circumferential end parts of the pole shoe may be formed so that a distance of the inner circumferential surfaces of the circumferential end parts of the pole shoe from the outer circumferential surface of the rotor increases as the inner circumferential surfaces of the circumferential both end parts of the pole shoe is far away circumferentially from a central line CL of the pole shoe.
