Abstract
The invention relates to the technical field of motors, in particular to a multi-pole motor rotor which comprises a plastic magnetic ring formed in integrated injection mode and a rotating shaft embedded in the magnetic ring. The magnetic ring is of an integral structure formed by injection molding of magnetic materials, at least two pairs of magnetic poles are formed on the surface of the magnetic ring in injection mode, and the magnetic poles are evenly distributed in the magnetic ring body with polarity reversed. The multi-pole motor rotor is formed by magnetic materials in one-step mode, and the rotating shaft serves as an insert in one-step forming, so that the concentricity of the rotor and uniformity of the quality are ensured, simultaneously a plurality of magnetic poles are formed in injection mode during forming, and the manufactured magnetic rotor has a multi-pole magnetic field.
Description
Technical field
The present invention relates to technical field of motors, especially a kind of multipolar dynamo rotor.
Background technology
Electrical micro-machine has been widely used in the fields such as automation, electromechanics now.Be widely used multi-pole magnet-ring as rotor in the fields such as electrical micro-machine and stepping motor, add outside in coil by after a pulse current, rotor just turns over a fixing angle.
Traditional multi-pole magnet rotor is to use bonding the forming of polylith magnet, but is difficult to processing when making small-sized electrical micro-machine, owing to being many magnetic patch splicings, is difficult to the magnetic pole angle is done accurately simultaneously.Be difficult to accomplish that whole rotor quality is even during simultaneously due to splicing, make the dynamic balancing of rotor poor, increased vibration and the noise of motor, affect motor performance.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides between a kind of distance between two poles of simple in structure, multi-pole magnet and magnetic pole angle multipolar dynamo rotor accurately.
The technical solution adopted for the present invention to solve the technical problems is: a kind of multipolar dynamo rotor is provided, comprise integrated injection molding plastics magnet ring and the rotating shaft that is embedded in magnet ring, described magnet ring is the injection molded integrative-structure of magnetic material, the surface injection of magnet ring has a plurality of magnetic poles, and described magnetic pole is evenly arranged in magnetic ring body by the polarity of mutually putting upside down.
Described magnet ring is columnar structured.
Described magnetic pole is arc-shaped structure.
The invention has the beneficial effects as follows: the present invention is the one-time formed rotor of magnetic material, rotating shaft is also as the inserts in one-shot forming, guarantee the concentricity of rotor and the uniformity of quality, injected simultaneously a plurality of magnetic poles in moulding simultaneously, made the magnet rotor of making have multipole magnetic field.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing embodiment.
Fig. 1 is structural representation of the present invention.
Fig. 2 is left TV structure schematic diagram of the present invention.
In figure: 1. magnet ring, 2. rotating shaft, 3. magnetic pole.
Embodiment
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to illustrate the present invention rather than limitation of the invention further.
Multipolar dynamo rotor as shown in Fig. 1～2, comprise integrated injection molding plastics magnet ring 1 and the rotating shaft 2 that is embedded in magnet ring 1, magnet ring 1 is the injection molded integrative-structure of magnetic material, the surface injection of magnet ring 1 has a plurality of magnetic poles 3, and magnetic pole 3 is evenly arranged in magnet ring 1 body by the polarity of mutually putting upside down.
Magnet ring 1 is columnar structured.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to the claim scope.
