Technical Field
The utility model relates to the field of permanent magnet transmission equipment, in particular to permanent magnet transmission equipment based on halbach arrays.
Background
The permanent magnetic transmission equipment is characterized in that a conductor material on a conductor disc cuts magnetic lines on the permanent magnetic disc to generate eddy current to form an induction magnetic field, and the permanent magnetic field and the induction magnetic field interact to transmit torque; the larger the distance between the conductor disc and the permanent magnetic disc is, the lower the torque efficiency is, the larger the distance between the conductor disc and the permanent magnetic disc is, and the speed regulation is realized by adjusting the gap between the conductor disc and the permanent magnetic disc. If the gap between the conductor disc and the permanent magnet disc is fixed, the coupler function can be realized. These two devices are collectively referred to as permanent magnet drive devices (permanent magnet eddy current drive devices).
The permanent magnet disc structure of the existing permanent magnet transmission equipment adopts aluminum or other non-magnetized materials to process permanent magnet positioning grooves, and then permanent magnets are arranged at intervals of polarity N-S; if the transmission torque of the permanent magnet transmission device needs to be increased, the number of permanent magnets and the size of a conductor disc need to be increased, and accordingly the cost of the device is increased.
Therefore, there is a need for a permanent magnet transmission device based on halbach array, which can solve the problems of large volume and limited transmission torque of the existing permanent magnet transmission device.
