Abstract
The invention relates to a four-coil claw pole type permanent magnet synchronous motor. The four-coil claw pole type permanent magnet synchronous motor comprises a shell, a central shaft which is hinged in the inner center of the shell, and a coil group, a lower magnetic ring, an upper magnetic ring, a rotor tooth and an extension shaft, which are arranged in the shell, wherein the extension shaft extends out of the upper part of the shell; the lower magnetic ring, the upper magnetic ring and the rotor tooth are integrally formed by injection molding and sleeved in the middle of the central shaft; the coil group is formed by laminating four coils; claw pole plates are arranged at two ends of each coil; an outgoing line is welded at the tail end of each coil; a bracket is arranged on the upper part of the coil group; a fixed shaft is riveted on the bracket; a duplicate gear is arranged on the fixed shaft; and an extension shaft tooth is formed on the extension shaft by injection molding. In the same usable area range, the height of the shell of the motor is increased; in a double-driving mode of the lower magnetic ring and the upper magnetic ring, the output torque of the motor is greatly improved, and the power of the motor is improved; and the four-coil claw pole type permanent magnet synchronous motor can be applied to the wider field of automatic production.
Description
Technical field
The present invention relates to the magneto technical field, especially relate to a kind of four layer line circle claw-pole permanent magnet synchronous motors.
Background technology
As everyone knows, permagnetic synchronous motor is that the drive motors of actuating force is provided for some automation equipments.Permagnetic synchronous motor in the past is all to adopt a rotor and two groups of coils to be contained in inside casing, and support, gear, intermediate plate, shaft, cover plate, circlip for hole are housed above rotor.Its limitation is: a rotor and two groups of coils are limited to the actuating force that motor provides, and can not satisfy the occasion needs of high-torque, have limited the scope of application of motor.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides that a kind of actuating force is stronger, more powerful, four layer line circle claw-pole permanent magnet synchronous motors in the automation equipment that can be used in wider model.
four layer line circle claw-pole permanent magnet synchronous motors of the present invention, comprise casing, be riveted on the central shaft at center in casing, be loaded on the coil groups in casing, lower magnet ring, upper magnetic ring, rotor tooth and shaft, shaft stretches out from casing top, described lower magnet ring, upper magnetic ring and rotor tooth are injection molded into sleeve integrating at the middle part of central shaft, described coil groups is comprised of four layer line circle stacks, the two ends of every layer line circle all are equipped with the pawl pole plate, lead-out wire is welded on coil end, a support is equipped with on the top of described coil groups, on support, riveted joint has fixed axis, duplicate gear is housed on fixed axis, intermediate plate is equipped with on the top of described support, the little copper sheathing of riveted joint on intermediate plate, described shaft is fixed on little copper sheathing, the shaft tooth is arranged in the shaft injection moulding, when rotor tooth rotates, rotor tooth drives duplicate gear and rotates, duplicate gear drives the shaft tooth and rotates, and then the drive shaft rotates.
Further, the bottom of described central shaft is provided with the adjustment spring.
Further, ball bearing is installed, at the in-built porose circlip of using of the groove of casing in the top capping plate of described shaft tooth, cover plate central channel.
Compared with prior art, beneficial effect of the present invention is: the present invention improves the height of motor case in identical usable floor area scope, adopt lower magnet ring and the two-layer driving of upper magnetic ring, greatly improve the output torque of motor, increase power of motor, go for automated production field widely.
