Ventilation Fan Motor Magnets For Cars

We make ventilation fan motor magnets for cars for seat cooling and dashboard fans. These parts are small, often weighing just a few grams. Our 22-year experience with small-size magnets gives us an edge. We hold dimensional tolerance to ±0.2 mm, which is tighter than our larger parts. Our grinding lines use fine-grit wheels for these tiny arcs. Our press operators change molds quickly to handle different sizes. We test every batch of product with a specialized fixture. The fixture measures arc height and chord width simultaneously. This speed lets us check more pieces per batch. Our product deliver stable flux even in compact motor designs.

We use Y30H and Y33 grades for ventilation fan motor magnets for cars. Remanence goes from 380 to 430 mT. Coercivity ranges from 210 to 270 kA/m. These numbers are similar to larger magnets but achieved in a smaller volume. That means higher energy density. High energy density allows the fan motor to be smaller and lighter. This is important for seat frames where space is tight. Our working temperature limit is -20°C to 180°C, which matches cabin conditions. We also check density at 4.8 – 5.0 g/cm³. Consistent density means consistent magnetic output. Our product are inspected for flux on every pressing shift.

Ventilation fan motor magnets for cars are in higher demand as seat cooling becomes popular. Our customers include motor makers who supply 20,000 USD class vehicles. We also ship to aftermarket parts distributors. Packaging uses blister trays inside cartons. This protects small parts during transport. MOQ is 100,000 pieces, but we are open to smaller trial orders for new customers. Sample lead time is 10 days if we have existing tooling. New tooling takes 45 days. We support EXW and FOB. Payment is 30% deposit and 70% before shipment. We can also apply anti-rust coating if needed. Our product are a small but important part of modern cabin comfort.
