Elevator Motor Permanent Magnet WARNINGS:
All neodymium magnets are unsuitable for children; do not ingest.
All neodymium magnets are brittle; do not allow these magnets to jump together or to an iron/steel surface – they will break, crack, chip or shatter. Neodymium-Iron-Boron Segment N42SH Magnets for Elevator Motors
Thin neodymium magnets DO NOT FLEX, if you attempt to flex them they will snap in half.
Shapes and magnetization orientations of motor magnets: Ring shapes and arc segments magnetized through diameter are most common for motor magnets. According to specific demands and drawings from customers, China Rare Earth Magnet Company MPCO can supply a variety shape of motor magnets including block, disc, wedge and heteromorphic shapes.

The most widely used magnetic material for motors are sintered neodymium material and SmCo magnets material. Sintered neodymium magnet features great magnetic strength which can bring large torque for rotors and stators. Among sintered NdFeB grades, the H, SH, EH and UH series are popular in that they can withstand working temperature up to 100-200 degree C without losing magnetism. Permanent Tile Magnet
The application of bonded neodymium material in motors is wide spread too for its great flexibility of producible shapes and magnetization orientations. For example, we produced and magnetized a diameter 30mm ring shape bonded NdFeB magnet into 16 poles and 32 poles through diameter, which is not achievable for any other sintered permanent magnetic material.

Sintered NdFeB term definition:
Main magnetic properties:
Residual magnetism (Br) including permanent magnet material, magnetic polarization coercivity (inner coercivity) (Hcj) magnetic induction coercivity (Hcb), maximum magnetic energy product ((BH)max)
Auxiliary magnetic properties:
Including permanent magnet material relative recovery permeability (μrec), remanence temperature coefficient (α (Br)), magnetic polarization coercivity temperature coefficient (α (Hcj)), Curie temperature (Tc)
Sintered NdFeB magnets are classified into low coercivity N, medium coercive force M, high coercive force H, ultra high coercive force SH, ultra high coercivity UH, extremely high correction according to the coercive force of magnetic polarization. Tenacious EH six products
Each product is divided into several grades according to the maximum magnetic energy product size.
N35-N52, N35M-N50M, N30H-N48H, N30SH-N45SH, N28UH-N35UH, N28EH-N35EH
Example of grade: 048021 denotes sintered NdFeB permanent magnet material with (BH)max of 366~398kj/m and Hcj of 800KA/m.
