GM902 Magnet Analyzer System combines the actual needs of multi poles magnetic ring manufacturers and motor enterprises users


GM902 Magnet Analyzer System combines the actual needs of multi poles magnetic ring manufacturers and motor enterprises users,through careful design of the test bench and precise control of the motor, to achieve accurate measurement of the surface magnetic field distribution.Test reports such as XY coordinate, P polar coordinate, 3D magnetic field distribution and harmonic analysis of relative fundamental wave can be provided ,which provide accurate magnetic field distribution data for motor design.The high concentricity design and the high precision level of the probe return are the guarantee of the quality of the equipment, and the comprehensive performance of the product reaches the international advanced level.


With the increasing demand for the quantity and quality of the motor, the production of the multi pole magnetic ring is required. How to develop and produce high-quality multipole magnetic rings, how to identify the quality of multipole, how to use the magnetic rings to design high-quality motors all put forward higher requirements for the inspection of the magnetic rings. In the past, the method of combining hand with simple fixture was far from meeting the use requirements because of large error, low precision, long time consuming and few inspection indexes.
