Abstract
The present utility model relates to a motor technology field, especially to a multipole motor rotor. The multipole motor rotor comprises an integrated injection moulded plastic magnet ring and a rotating shaft embedded in the magnet ring, wherein the magnet ring is an integrated structure formed by a magnetic material injection, and a surface of the magnet ring is injected with at least two couples of magnetic poles which are uniformly arranged inside the magnet ring body with polarities reversing each other. The present multipole motor rotor, as a rotor formed by a one-step moulding with the magnetic material, and the rotating shaft, as an insert of the one-step moulding, together ensure the concentricity of the rotor and the uniformity of quality, and at the same time, a plurality of magnetic poles are injected simultaneously upon moulding, thereby enabling the prepared magnetic rotor to have multipole magnetic fields.
Description
Technical field
The utility model relates to technical field of motors, especially a kind of multipolar dynamo rotor.
Background technology
Electrical micro-machine has been widely used in fields such as automation, electromechanics now.In fields such as electrical micro-machine and stepping motor, be widely used multi-pole magnet-ring as rotor, add outside in the coil through behind the pulse current, rotor just turns over a fixing angle.
Traditional multi-pole magnet rotor is to use that the polylith magnet is bonding to form, but when the manufacturing small-sized electrical micro-machine, is difficult to processing, owing to be 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 owing to splicing, make that the dynamic balancing of rotor is poor, increased the vibration and the noise of motor, influence motor performance.
The utility model content
The technical problem that the utility model will solve is: based on the problems referred to above, angle multipolar dynamo rotor accurately is provided between a kind of distance between two poles and magnetic pole of simple in structure, multi-pole magnet.
The utility model solves the technical scheme that its technical problem adopted: a kind of multipolar dynamo rotor; Comprise integrated injection molding plastics magnet ring and be embedded in the rotating shaft in the 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 the magnetic ring body by the polarity of putting upside down each other.
Described magnet ring is columnar structured.
Described magnetic pole is an arc-shaped structure.
The beneficial effect of the utility model is: the utility model is the one-time formed rotor of magnetic material; Rotating shaft is also as the inserts in the one-shot forming; The concentricity of rotor and the uniformity of quality have been guaranteed; Simultaneously injected a plurality of magnetic poles simultaneously, made the magnet rotor of processing have multipole magnetic field in moulding.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left TV structure sketch map of the utility model.
Among the figure: 1. magnet ring, 2. rotating shaft, 3. magnetic pole.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of multipolar dynamo rotor shown in Fig. 1～2; Comprise integrated injection molding plastics magnet ring 1 and be embedded in the rotating shaft 2 in the 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 putting upside down each other.
Magnetic pole 3 is an arc-shaped structure.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
