Problems solved by technology

[0004] Generally, the insulating bracket of the motor is generally manufactured by high temperature die-casting. The bottom end surface of the winding part of the existing insulating bracket is solid. During the cooling process after the die-casting is completed, the flatness of the surface will be poor due to the shrinkage rate. Installed on the stator core of the motor, there will be a gap between it and the end face of the stator core, and even the installation is not stable, which will affect the winding of the motor

Abstract

The invention provides an insulation bracket and a motor. The insulation bracket includes an outer wall and multiple winding portions; the multiple winding portions are disposed on the inner surface of the outer wall, and each of the winding portions include a bottom plate; and the bottom plate extends from the inner surface of the outer wall to an inner space formed by the outer wall and is usedfor connecting to a stator core of the motor, wherein the bottom plate includes a recess portion, and one side of the bottom plate of each of the winding portions that is connected to the stator coreis provided with a flat surface. The insulation bracket can effectively improve the flatness of end surfaces of bottoms of the winding portions, and avoids occurrence of a gap between the insulation bracket and the stator core.

Description

technical field [0001] The invention relates to the field of motors, in particular to an insulating bracket and a motor with the insulating bracket. Background technique [0002] At present, due to the wide application of electric power, motors can be used in various aspects of daily life and industrial production. The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The main function of the motor is to generate driving torque as a power source for electrical appliances or various devices. [0003] The motor is mainly composed of a stator and a rotor. The stator includes a stator core and a stator winding, and insulation protection is required between the stator core and the stator winding. For the concentrated winding permanent magnet synchronous motor, the insulation protection between the end face of the stator core and the end of the stator winding usually adopts an insu...
