Abstract

The invention provides a motor insulating framework and a motor having the framework. The motor insulating framework comprises an upper framework and a lower framework. The upper framework and the lower framework are fixedly connected. The lower framework comprises a first side wall and a second side wall. The second side wall is arranged in a way to be spaced from the first side wall to form a wire winding groove of the lower framework. One second side wall side far away from the wire winding groove is provided with a plurality of wire arranging grooves. The wire arranging grooves are sequentially arranged along the height direction of the lower framework. The motor insulating framework further comprises a winding part located between the first side wall and the second wall and connected with both the first side wall and the second side wall. By means of the motor insulating framework, windings of different phase lines can be separated in terms of the direction. Therefore, a short circuit caused by intersection of different phase-line windings can be prevented.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor insulating frame and a motor having the same. Background technique [0002] Generally, the motor body is composed of stator, rotor, casing and other components. The stator includes stator core, insulation structure and winding. The winding is usually enameled wire. At present, there are many defects in the insulation structure used in motors. For example, the windings are distributed on different stator insulation frames, and the windings of different phase lines cross each other, and there is contact. When bare copper is used, a short circuit will occur between the windings between the phases, and the stator may be broken down, which poses a great risk to the safe operation of the motor. There is a gap between two adjacent insulating frames of the stator, which may easily cause insufficient electrical creepage distance, and the windings of two different phase lines are likely to t...
