Technical Field
The invention relates to the technical field of motors, in particular to a sectional winding type concentrated winding stator insulation rubber sleeve.
Background
The traditional original concentrated winding stator uses a single-wire slot design for an insulating rubber sleeve, and has great limitation on the number of parallel windings and the wire diameter of a stator coil. In the field of three-phase alternating current motors used by low-voltage low-speed vehicles, the number of turns in a motor stator winding scheme is small, and the number of parallel windings is large.
If the insulating rubber sleeve designed by the conventional single-wire slot is adopted, all enameled wires wound in parallel are required to be wound together to the end, the requirement on the power of the winding machine in the current industry is high, the power of the common winding machine is low, the enameled wires cannot be wound at all, and meanwhile, the notches of the stator core need to be designed into large-size notches, so that the performance of the motor is adversely affected.
Meanwhile, the motor stators with a large number of parallel windings are wound for several times, and then the wire ends are combined together, so that the problem of high motor power of the winding machine is solved, but because the wire arrangement sequence of the single-slot wire frame is from inside to outside, the total circumference length of the coil wound firstly is smaller than that of the coil wound later, and because the coil wound later is wound on the outer layer of the coil wound in front, the resistance of the coil wound in each time is different, so that the resistance of the stator coil is unbalanced, the running performance of the motor is influenced, and even the motor is burnt out.
