The invention discloses an inner rotor motor stator which is made without enameled wire, and belongs to the technical field of motors. The inner rotor motor stator comprises a stator disk 1, a winding2, a permanent magnet ring 4; that the stator adopts a double-sided printed circuit board to make a plurality of copper foil coils which are left on the outside at the head and the tail and connectedin series to form a winding 2, At high vacuum and ultra-low temperature state, that winding is seal and packaged by a filler 3 by powder metallurgy method, and is made by vacuum hot pressing, high temperature sinter and aging treatment, so that the winding 2 is always kept in high vacuum state in the stator, and the memory trace of ultra-low temperature and high temperature is kept, and the superconducting effect is exerted when the motor is assembled; In which the magnetic levitation action of the magnetic levitation ring 4 is utilized, the clearance between the rotor and the stator can be controlled to a minimum, The ultra-thin stator made with printed circuit board windings greatly improves the efficiency of the motor, up to 95%. Moreover, the ultra-thin stator lamination can be conveniently increased due to its high temperature resistance, moisture resistance and corrosion resistance, so as to manufacture the high-power superposed inner rotor motor and generator without enamelledwires.
Description
technical field [0001] The invention relates to the technical field of motors. It is an inner rotor motor stator that does not need enameled wires. generator stator. Background technique [0002] Ironless coil permanent magnet motors in the prior art, for example, Chinese patent announcement number, CN102035331A discloses a permanent magnet motor with multi-center ironless coils. Since the stator without high temperature superconducting materials and enameled wires is not used, the efficiency Not ideal enough to reach the 95% level. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects, and realize it by adopting a technical scheme of an inner rotor motor stator that does not need to be made of enameled wire. [0004] An inner rotor motor stator made without enameled wire, comprising: a stator disk 1 and a winding 2 inside the disk, a magnetic levitation ring 4, and a sensor 6 sealed and packaged by a filler 3,...
