A moving prevention device of a motor stator slot wedge comprises a stator iron core. A groove is formed in the stator iron core. A coil is arranged inside the groove, slot insulation is arranged between the coil and the groove, the slot wedge is arranged at an opening of the groove or between a main winding and a secondary winding inside the groove, the length of the slot wedge is larger than that of the part, located at the position where the slot wedge is placed, of the slot insulation, and the two ends of the slot wedge are provided with forks for fixing the slot insulation respectively. The forks of the slot wedge are fixed with the slot insulation through a buckling structure. The cross section of each fork of the slot wedge is in an arc shape. Or, the cross section of each fork of the slot wedge is in a bar shape. The two ends of the slot wedge are provided with the forks for fixing the slot insulation respectively, the movement of the slot wedge is prevented, the electric leakage and other serious safety accidents are prevented, the reliable operation of a motor is guaranteed, the degree of safety is improved, and the moving prevention device has the advantages of being low in manufacturing cost and simple in manufacturing technology.
Description
technical field [0001] The invention relates to a motor stator slot wedge, in particular to a device for preventing movement of the motor stator slot wedge. Background technique [0002] When the motor works for a long time, due to electromagnetic vibration and other reasons, the slot wedge of the motor will move, which will cause poor insulation of the coil, and in severe cases, serious safety accidents such as electric leakage. Therefore, the conventional method is to impregnate the motor stator winding with paint. Secure the coil and wedges. However, the cost of impregnating paint for this stator wedge fixing structure is relatively high, and special equipment is required. For this reason, engineers and technicians have carried out improvement, disclosed a kind of anti-movement device of motor stator slot wedge as Chinese Patent Document No. CN101534030A on September 16, 2009, comprises stator iron core, is provided with groove on the stator iron core, The coil is set i...
