BLDC Ceiling Fan Stator Lamination Stacks Manufacturer

We’re a factory dedicated to manufacturing lamination stacks that form the very heart of high-performing, energy-efficient motors. And here at Sino, crafting these precision components isn’t just what we do; it’s our passion.

The Sino Secret Sauce for Superior Performance

The material we choose for Sino’s bldc ceiling fan stator laminations is a highly specialized electrical steel, typically a silicon steel alloy.

Adding a specific percentage of silicon to iron does a couple of brilliant things:

It significantly increases the material’s electrical resistivity. Higher resistivity means eddy currents find it much harder to flow – another win for efficiency!
It can also help to reduce those pesky hysteresis losses we talked about.

At Sino, our material scientists and engineers work closely with our steel suppliers. We specify particular grades known for their excellent magnetic permeability (how easily they can be magnetized and demagnetized) and low core loss characteristics.

Sino's Manufacturing Edge on Lamination Thickness

Thinner laminations (often in the range of 0.35mm to 0.5mm for many BLDC ceiling fan stators) provide more layers of insulation in a given stack height, further disrupting those energy-sapping currents. However, going too thin can dramatically increase the number of laminations needed, which can ramp up manufacturing complexity and cost. It can also make the stack less mechanically robust if not handled correctly. At Sino, we work with you to determine the optimal thickness for your specific bldc ceiling fan stator design, considering your performance targets, operational frequency, and cost considerations.

Precision Stamping and Stacking

Each lamination needs to be stamped or laser-cut with incredible accuracy. Because:

Burr Control

Any tiny burrs or rough edges left from the cutting process can pierce the crucial insulating coating between laminations. If that happens, a short circuit occurs, allowing eddy currents to flow across laminations, negating much of the benefit of having laminations in the first place! Sino employs advanced stamping dies made from high-durability carbide, along with rigorous deburring processes and quality checks, to ensure burr formation is minimized to almost imperceptible levels. For highly complex or prototype designs, we also leverage precision laser cutting.

Insulation Integrity

The insulating coating itself (often an organic varnish or an inorganic oxide layer) must be uniform and robust. Sino uses specially formulated coatings designed for excellent dielectric strength and adhesion, applied under controlled conditions.

Stacking Accuracy

Once the individual laminations are perfect, they need to be stacked together with extreme precision. Misaligned laminations can lead to an uneven magnetic field, increased vibration, and more audible noise – exactly what you don’t want in a premium ceiling fan. Our automated stacking processes, often incorporating interlocking features stamped into the laminations themselves, ensure a tight, perfectly aligned core. This not only guarantees optimal magnetic performance but also contributes to the fan’s overall mechanical stability and quiet operation.
