Description
Technical field
The utility model belongs to technical field of motors, relates to a kind of rotor of permanent magnet disc motor.
Background technology
ventional disc magneto adopts adhesive to be fixed on disc rotor motor by permanent magnet mostly, or adopt in the inner mosaic magnet of rotor disk, permanent magnet is pushed down afterwards by a bulk of pressing plate entirety, these two kinds of frame modes all can affect the raising of power of motor density, efficiency greatly, especially in the latter's pressing plate, eddy current loss is bigger than normal, easily cause rotor disk to generate heat, there is certain risk, reduce the performance of motor.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of permanent magnet machine rotor that can reduce eddy current loss, improve motor working efficiency.
Permanent magnet machine rotor of the present utility model, comprise rotor disk, multiple magnet, for magnet being fixed on briquetting in rotor disk and connector, magnet is eccentric circular ring structure, and the cross sectional shape of the radial direction of described magnet is the trapezoidal structure combined overlapped by two bottom surfaces; Described rotor disk is along the circumferential direction distributed with the installation slotted eye of the multiple eccentric circular ring structures matched with magnet;
Match with the end face of magnet in described one end of installation slotted eye; The other end is provided with the conical surface matched with the half of the end face of magnet and the mounting groove for installing briquetting be connected to outside the described conical surface, described briquetting is provided with second half conical surface matched with the end face of magnet;
The rotor disk at described briquetting and mounting groove place is respectively arranged with the installation through hole and screwed hole that arrange along rotor disk axial direction, briquetting is arranged on rotor disk through installation through hole and screwed hole by connector, and then is pressed abd fixed on rotor disk by magnet.Whole apparatus structure is compact, takes up room little, convenient and flexible installation.
The two ends of installing slotted eye can need reversed position according to design of electrical motor, the mounting groove of briquetting can be arranged on one end of the position near rotor disk center, also the mounting groove of briquetting can be arranged on one end of the position away from rotor disk center.
Described installation slotted eye runs through rotor disk, the consistency of thickness of described magnet and rotor disk.After installation, rotor disk, magnet, briquetting are in sustained height, and the distance between whole rotor disk and stator reduces a lot, make whole apparatus structure compacter.Compared with a traditional monoblock briquetting, each briquetting of this device both met installation requirement, took again very little space, decreased the weight of rotor, effectively improved motor working efficiency.
Described magnet can be an en-block construction, can comprise two trapezoidal piecemeals, and is spliced by described two trapezoidal piecemeal bottom surfaces coincidences, also can comprise three fan-shaped piecemeals, and is spliced by three fan-shaped piecemeal sides coincidences.Along with the increase of the quantity of the magnet piecemeal installed in slotted eye, eddy current loss is also more and more less, and rotor heating is also more and more less, and the demagnetization possibility of magnet also just reduces, and adds the reliability of motor.
