Abstract

The invention discloses a stator armature test system which comprises a cooling liquid circulation system, a stator armature test device, a to-be-tested stator armature, a frequency converter and a test system, wherein the cooling liquid circulation system provides circulating cooling liquid for the stator armature test device by virtue of a pipeline; the stator armature test device is composed ofa base, a box frame and a non-magnetic arc plate; the test system is connected with a sealed aviation plug; the frequency converter is connected with sealed wiring bus-bars; a liquid inlet pipe and aliquid outlet pipe are arranged on the stator armature; and cooling liquid circulates in the cooling liquid circulation system by virtue of a pipeline. The invention further discloses a test method for the test system. According to the test system, actual operating states of a pair of polar stator armatures can be reasonably simulated, and the temperature distribution and strain of the stator armatures can be tested, so that whether a soaked liquid cooling manner meets the temperature rise requirement of a high heat load stator armature and whether stress-strain of the manner meets the strength requirement of the stator armature can be verified.

Description

technical field [0001] The invention belongs to the technical field of performance testing, and relates to a test system and a test method, in particular to a test system and a test method for an immersion-type liquid cooling stator armature, which are used for simulating and assessing the stator armature in an equivalent immersion-type liquid environment. Strain and temperature distributions under loss. Background technique [0002] For some special motors with small size, light weight, high heat load and high torque density, the loss per unit volume and operating temperature rise are larger than conventional motors with the same capacity. Under the premise of satisfying the electromagnetic performance of the motor, in order to effectively control the temperature rise of the motor, the stator armature generally adopts liquid cooling methods, mainly including winding water cooling, liquid cooling in the tank, and immersion liquid cooling. Considering the molding process, th...
