* A permanent magnet motor is a type of electric motor that uses permanent magnets in addition to windings on its field, rather than windings only. Permanent magnet motors are more efficient than induction motor or motors with field windings for certain high-efficiency applications such as electric vehicles.

Silicone Steel Info
Electrical steel (E-steel, lamination steel, silicon electrical steel, silicon steel, relay steel, transformer steel) is speciality steel used in the cores of electromagnetic devices such as motors, generators, and transformers because it reduces power loss. It is an iron alloy with silicon as the main additive element (instead of carbon). The exact formulation is tailored to produce specific magnetic properties: small hysteresis area resulting in low power loss per cycle, low core loss, and high permeability.
Electrical steel is usually manufactured in cold-rolled strips less than 2 mm thick. These strips are cut to shape to make laminations which are stacked together to form the laminated cores of transformers, and the stator and rotor of electric motors. Laminations may be cut to their finished shape by a punch and die or, in smaller quantities, may be cut by a laser, or by wire electrical discharge machining.
Magnetic properties
Silicone sheet is made of iron-silicon alloy and is non-grain-oriented materials. The starting material is manufactured as cold-rolled strip. It has special physical properties and belongs to the soft magnetic materials. Here is an overview of the standard grades for use in motor core systems:
M235-35A
M270-35A
M330-35A
M235-50A
M270-50A
M330-50A
M530-50A
M400-65A
NO20-15

if you have other models number, pls kindly advise, we could cooperate.
Coatings
In order to prevent the short circuits between the lamellae in electrical sheet packs and thereby reduce the eddy currents, various coatings are applied to the strip. The coatings vary in thickness from 1 to 4 µm. Depending on the processing technology and subsequent application, coatings exist for better corrosion protection, improved insulation of the individual layers, heat resistance, improved punching properties or weldability.
* Coating C3 – Coating for improving the lubricating effect. Relevant, for example, for the stamping process.
* Coating C4 – Coating to improve corrosion protection and insulation resistance.
* Coating C5 – Coating to optimize the temperature resistance. Relevant e.g. for stress relieving after the stamping process.
* Coating C6 – Coating for a particularly high insulation resistance.
* Backcoat – Coating as a bonding technology for sheet packs and core sheets.

Magnet Plating and Coating Options
The following is a list and description of common plating options for custom magnets.Why do magnets need to be plated?
★ Oxidization (Rust)
NdFeB magnets will oxidize(rust) if left exposed. When a plating wears down or cracks, the exposed area will oxidize. An oxidized area will not result in complete degradation of the magnet, only the oxidized area will lose its strength. However the magnet will lose some structural integrity and become more susceptible to breakage.
★ Durability
Depending on shape, permanent magnet substrate is brittle. A multilayered metal plating like nickel or zinc improves the magnets resistance to chipping and wear, particularly around corners.
★ Harsh Environments
Platings vary in their tolerance of different harsh chemicals and abrasion. Salt and humidity in regions near the ocean are commonly overlooked when selecting aplating. Be sure to consider the magnets environment when selecting a plating.The most common type of plating for neodymium magnets Nickel (Ni-Cu-Ni) Intended for indoor use. It has proven to be very resilient when subjected to normal wear and tear. However it will corrode oudoors in prolonged exposure to salt water, salty air,or harsh chemicals.

Magnetization Direction
Application
Permanent Motor Rotor & Stator
Permanent magnet motors consist of two main types. Surface permanent magnet motors (SPM) and internal permanent magnet (IPM) motors. The main difference is that SPM motors place the magnets on the outside of the rotor while IPM motors place their magnets inside the motor. Benefits to internal magnets include structural integrity and reducing Back EMF. Since holes must be cut into the rotor for the placement of the magnets this creates areas of high reluctance allowing carmakers to some of the benefits of reluctance motors as well as permanent magnet motors.
Neodymium magnets are strong magnets,frequently used for many types of sectors, commercial, industrial & technical applications where strong permanent magnets are required. Due to their high-magnetic strength, components that previously had to be large and heavy can now be miniaturized by using Neodymium magnet material.Common Applications: holding systems requiring very high holding forces, sensors, reed switches, hard disc drives, audio equipment, acoustic pick-ups, headphones & loudspeakers, MRI scanners, magnetically coupled pumps · motors & generators, magnetic tool holders, magnetic bearings, door catches, dental instruments, medical devices, magnetic separators, lifting machinery, crafts & model making, hanging artwork, levitation devices, POP displays, commercial signage, packaging closures, jewelry clasps & more.
