4 8 16 32 Poles Ring Shape NdFeB Neodymium Magnet For Motor

Magnetic 4 8 16 32 Poles Neodymium Bonded Ring Magnet For Motor

Bonded magnet materials can be created through Injection Molded and can be made from NdFeB, Strontium Ferrite or a combination of the two. Bonded magnets that are created through injection molding can be molded into complex shapes and also molded directly onto components. Bonded magnets can also be created through the process of compression bonding which offer higher magnetic output but are limited to simpler geometries than Injection Molded materials. Compression Bonded magnets can be made from either NdFeB or SmCo powders.

Feature

Injection Molded:

Binder Types / Nylon / PPS / Polyamide.

Temperature Range -40c – 180c

Very Tight tolerances off tool ( 0.002 -0.003 Typical )

Very good mechanical strength

Compression Bonded:

Higher Magnetic Strength due to higher magnetic particle density.

Epoxy Binder / Resistant to normal industrial solvents and automotive fluids

Epoxy Coat after manufacturing to prevent oxidation

Temperature Range -40c – 165c

“Tight” tolerances off tool

Good mechanical strength

Typical Bonded Magnet Applications:

Sensors

Brushless DC Motors

General Bonded Magnet Applications:

Materials are isotropic and can be magnetized in any direction

Wide range of existing tool sizes are available in rings, discs and rectangles

Exsisting Multipole magnetizing fixtures for quick prototyping

Easily machined

Existing Multipole rings simplify assembly verse arc sepments

Packing:
As the magnets have strong attraction and we will use the spacer to apart the magnets each other in case people will be hurt when take it out. Then, they will be packed in a white box of pieces each, several boxes to a carton.

+By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.
+By Sea: If the goods are will be shipped by sea, we will place a pallet on the bottom of cartons.

Shipping:

Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.
A: The weight is under 40Kgs, we recommend to send them in shielding boxes to you by Express.
B: The weight is between 40Kgs-100Kgs, it can be sent by Express or Air.
C: The weight is over 100Kgs, we recommend to send them by Ocean.

Bonded magnet is Customized product.

Usually we ask for the following information.
• 1) Material type and grade(magnet force) required.
• 2) Size and shape, if available, a sketch or drawing with dimensions and tolerances.
• 3) Max working temperature.
• 4) Delivered magnetized or unmagnetized? Magnetization direction?
• 5) Quantities required.
• 6) Coating/plating required (if any)
• 7) Information on magnet application.
