Permanent Neodymium Motor Magnet (moto magnet)

High quality permanent rare earth Neodymium Motor Magnet

Quality Control and Sampling Plan:
Sampling plan for magnetic properties or dimensional attributes is performed according to the customer's specific requests. Otherwise we use MIL Standard 105D Sampling plan for normal inspection.
Magnetization and Magnetic Test Equipment:
Modes of magnetization :
Test Equipment:
* The magnetic properties of test samples are determined using a modern BH tracer potting a full loop demagnetization curve.
* High accuracy calibrated Gaussmeters, Fluxmeters, and some other necessary measuring tools are used for appropriated parts.
Physical and Magnetic Tolerance:
In the absence of clear instruction on magnetic and physical tolerances, we use Magnetic Material Producers Association (MMPA) Standard Specification for Permanent Magnet Material as a guideline.

NdFeB Magnet Processing

Required Information for Quotation:
