Embodiment Construction
[0019] Referring to the accompanying drawings, it is a detection device for the test operation of the stator of an AC external rotor motor. A vertical column shaft 2 is arranged in the center of the base 1. In order to facilitate the installation of the base 1, the outer diameter D of the base 1 is smaller than the winding iron core 6 The inner diameter of the inner diameter of the column shaft 2 is provided with a supporting rotating device 3; a metal ring 4 is suspended and fixedly connected to the supporting rotating device 3 through the connecting grid bar 5; in order to improve the detection accuracy, the height H of the metal ring 4 is equal to the winding iron core 6 The height, the inner diameter d of the metal ring 4 is greater than the outer diameter of the winding iron core 6, the inner diameter d of the metal ring 4 is set on the outer diameter of the winding iron core 6 and a uniform gap 7 is maintained.
[0020] When in use, first place the base 1 and the column s...

Description
technical field [0001] The invention relates to a detection device, in particular to a detection device for the trial operation of the stator of an AC external rotor motor. Background technique [0002] In the production process of the existing three-phase AC motor, after the winding iron core has embedded wires, in order to check whether the embedded wires correctly generate a rotating magnetic field, it is necessary to test whether the rotating magnetic field exists by energizing it. The specific process of the detection is: for example, the stator of the Y series three-phase asynchronous motor (belonging to the inner rotor motor), after the power is turned on, the inner surface of the stator will generate a rotating magnetic field. Generally, a steel ball can be placed on the inner surface of the stator and pressed by hand. After the direction of the rotating magnetic field is shifted, the steel ball will continuously rotate along the inner surface of the stator under the...
