Motor magnet sourcing
For motor projects, the first question is simple: do you need stable cost, compact force, or a specific arc shape? CIYI can review ferrite and NdFeB motor magnet requests from drawings, photos, or samples.
Ferrite arc magnets are common when the buyer needs steady cost and repeat supply. NdFeB arc or block magnets make sense when the motor has less space but needs stronger magnetic force.
For a first quote, send the magnet drawing, material if known, magnetization direction, tolerance, quantity, and how the magnet sits inside the motor assembly.
CIYI supplies ferrite magnets, NdFeB magnets, and custom magnet shapes for B2B OEM and wholesale buyers. Motor magnet orders can be reviewed together with sample confirmation, packing method, and export carton needs.
Test reports or compliance documents can be discussed by order requirement.
Material choice
The best choice depends on force, space, temperature, cost target, and the way the magnet will be assembled.
| Option | Often chosen when | Details to confirm |
|---|---|---|
| Ferrite arc magnets | The motor needs stable cost, standard ceramic material, and repeat carton orders. | Arc radius, thickness, length, pole direction, tolerance, and tooling status. |
| NdFeB arc magnets | The design needs stronger force in a smaller space. | Grade, coating, temperature series, corrosion risk, and magnetization direction. |
| Blocks or segments | The magnet is part of a fixture, rotor, or custom assembly. | Drawing, assembly position, pull force target, and surface treatment. |

A small amount of technical detail avoids a long back-and-forth.
Motor magnet FAQ
These answers are meant for early sourcing. Final material and dimensions should be checked against the actual motor design.
Yes. Ferrite arc and segment magnets can be reviewed from size, radius, pole direction, and quantity. Existing samples or drawings are the fastest way to start.
Use NdFeB when the design needs stronger force in less space. The quote will depend on grade, coating, temperature series, and tolerance.
Yes. Motor magnets are sensitive to pole direction. If you are not sure, send the old sample, assembly drawing, or motor layout.
A photo is enough for an early discussion, but tooling and price usually need a drawing or physical sample.
Tooling, material grade, coating, quantity, and inspection requirements all affect lead time. Repeat orders are usually easier to plan once the sample is approved.
