Embodiment Construction

[0023] Next, a unidirectional energization type brushless DC motor 1 (hereinafter referred to as "brushless DC motor") provided with an AC voltage output winding according to the present invention will be described with reference to the drawings. Such as Figure 1 to Figure 3As shown, the brushless DC motor 1 of the present invention includes a rotating body 2 and a frame 3 supporting the rotating body 2 . The rotating body 2 is configured such that two disks 5, 5', one disk 51, and one position detection disk 8 are fixed to a shaft 4 serving as a rotation axis at predetermined intervals via a spacer 40. On one surface of each disk 5, 5', four permanent magnets 6, 6' are arranged at equal intervals around the periphery of the disk 5, 5'. On the other hand, on the frame 3, four electromagnets 7 are fixed through the support member 3a corresponding to each of the four sets of permanent magnets 6 that are two in one set. The details will be described later, but one magnetic pole ...

Abstract

To provide a one directional electrification-type brushless DC motor having AC voltage output winding that can simultaneously show a function of a motor, which can continuously obtain constant torque, and a power generation function which can obtain continuous electromotive force. The DC motor is provided with a disk (5) fitted to a frame (3), a plurality of plate-like permanent magnets (6) arranged on the disk (5) at equal intervals at a periphery of the disk (5), magnetic body cores (70(A)) fixed to the frame (3) in accordance with a plurality of the permanent magnets (6), windings (71(A)) which are wound to the magnetic body cores (70(A)) and to which DC power is supplied, a prescribed number of magnetic body cores (70(B)) fixed to the frame (3) and windings (71(B)) wound to the magnetic body cores (70(B)) and connected to a power consumption device. The permanent magnets (6) are positioned in such a way that an angle that a straight line passing a center of the disk (5) and centers of the permanent magnets (6) and a normal line in a center of a magnetic pole face of the permanent magnet (6) make is set to be 0 DEG to 60 DEG .

Description

technical field [0001] The present invention relates to a unidirectional energization type brushless DC motor and a motor system provided with an AC voltage output winding. A brushless direct current motor with windings and a motor system including the brushless direct current motor. Background technique [0002] Conventionally, when generating electricity by rotating a motor, the motor and the generator are mechanically connected. However, a motor has the same structure as a generator, and is called a motor when electric power is supplied to rotate a rotating body to obtain a driving force, and is called a generator when an electromotive force is generated in a winding by rotating a rotating body with a driving force. Therefore, an attempt has been made to rotate a rotating body to function as a motor and to generate electricity by rotating the rotating body, that is, to use the same rotating body to simultaneously function as a motor and a generator. As an example of the...
