Abstract
The utility model relates to a magnet of a synchronous generator with a permanent magnet whose parts rotate around an armature, such as a flywheel magneto. A casing body is in the shape of a circular ring; 4 circular-arc-shaped Nd-Fe-B permanent magnets are respectively cemented to the inner and lateral surface of the circular ring; both ends of each of the Nd-Fe-B permanent magnets are respectively in fit connection with wedge strips with nonmagnetic conduction fixed poles. The utility model improves the performance of the engine of a motorcycle; the ignition energy is sufficient; the engine can be started easily; oil consumption is reduced obviously; deposited carbon between sparking-plug electrodes is greatly reduced; the brightness of an illumination lamp for night is greatly increased. Moreover, the utility model has the advantages of simple structure, easy fabrication, etc.
Description
The synchronous generator parts that the utility model includes permanent magnet are around the magnet of armature rotation, flywheel permanent magnetic motor for example, particularly a kind of neodymium-iron-boron permanent magnet magneto external rotor.
Employed magneto alternator on the at present domestic and international motorcycle, generally influence the performance of engine, exist the firing energy deficiency, start difficulty, it is unable to travel, and fuel consumption is big, serious carbon deposit between sparking-plug electrode, critical defects such as night light luminance shortage, the utility model is to overcome above-mentioned deficiency, has designed a kind of neodymium-iron-boron permanent magnet magneto external rotor.
The purpose of this utility model provides a kind of performance that improves motorcycle engine, causes the firing energy abundance, is easy to start, thereby reaches a kind of neodymium-iron-boron permanent magnet magneto external rotor that reduces carbon deposit between sparking-plug electrode.
The utility model is achieved in that housing is toroidal, on the annulus medial surface, ring groove is arranged, on the left surface of annulus fixed head is arranged, fixed head is connected with the annulus housing by gusset and is structure as a whole, fixed head has an axis hole between two parties, 6 fixedly riveted holes are arranged on the fixed head, in ring groove, be adhesively fixed with 4 circular-arc neodymium-iron-boron permanent magnets respectively, locate to kiss respectively to be connected to non-magnetic conduction fixed pole spline piece at the two ends of every circular-arc neodymium-iron-boron permanent magnet, each non-magnetic conduction fixed pole spline piece is by in the ring groove of non-magnetic conduction screw on annulus housing medial surface of housing.
Housing is toroidal, on the left surface of annulus, fixed head is arranged, fixed head is connected with the annulus housing by gusset and is structure as a whole, fixed head has an axis hole between two parties, 6 fixedly riveted holes are arranged on the fixed head, on the annulus medial surface, be adhesively fixed with 4 circular-arc neodymium-iron-boron permanent magnets respectively, kiss is connected to non-magnetic conduction fixed pole spline piece respectively at place, the two ends of every circular-arc neodymium-iron-boron permanent magnet, each non-magnetic conduction fixed pole spline piece by through the non-magnetic conduction screw of housing on the medial surface of annulus housing.
The utility model greatly improves the performance of motorcycle engine, make the common permanent magnet alternator internal magnetic field of magneto alternator internal magnetic field strength ratio intensity improve tens times, firing energy abundance during use, be easy to start, fuel consumption obviously reduces, and carbon deposit greatly reduces between sparking-plug electrode, and night light brightness heightens, and simple in structure, be easy to advantages such as manufacturing.
