Lamination Core Products - Sino Lamination Core Manufacturer

Short version: if it’s a stack of thin electrical steel doing magnetic work, we make it. Motor stators and rotors, transformer cores, EV traction cores, fan motor cores — and every step that holds them together, from stamping to annealing.

Forty-two product lines below, grouped by what they do. Pick the one that matches your design. Or skip the browsing, send us your drawing, and we’ll quote it.

1. Motor & Generator Cores

The workhorses. Rotating machines, most of them running at 50 or 60 Hz, built to sit on a production line for years without anyone thinking about them.

Motor Core Laminations — the general-purpose starting point. Stator, rotor, or both.
Stator Laminations — the half that doesn’t move. Holds the windings, carries the flux.
Rotor Laminations — the half that does. Balanced, tight-tolerance, usually the harder part to make.
Induction Motor Core Laminations — for squirrel-cage and wound-rotor AC motors.
Segmented Stator Laminations — big diameters that ship better in pieces. We cut them, then assemble.
Permanent Magnet Motor Laminations — tight tolerances for PM rotors and stators.
Axial Flux Stator Laminations — flat, disc-shaped cores for axial flux designs.
Linear Motor Stator Core Laminations — long, flat stacks for linear machines.
Armature Core Laminations — DC machine armatures, slots and all.
DC Motor Laminations — brushed and brushless DC cores.
Servo Motor Core Laminations — low cogging, high precision, built for motion control.
Stepper Motor Core Laminations — small, precise, high pole count.
Engine Laminations — cores that live in hot, vibrating places.
Cold Rolled Motor Laminations — cold rolled stock, priced for volume.
Laminated Soft Iron Core — when you need high permeability and low coercivity.

2. EV & BLDC Cores

Higher frequencies, thinner steel, tighter everything. This is where lamination quality shows up in your range numbers.

EV Motor Core Laminations — traction motors. Ultra-thin gauges, high slot fill, high volume.
BLDC Motor Core Lamination — brushless DC cores for drones, tools, pumps, e-bikes.

3. Fan Motor Cores

Fan motors run long hours at low load. Quiet matters as much as efficiency here, and we build for both.

4. Generator & Alternator Cores

Low speed, high pole count, decades of service. The efficiency margins are tight and the cores are big.

5. Transformer & EI / UI Cores

Grain-oriented steel, closed flux paths, and losses measured in fractions of a watt.

Transformer Laminations
EI Core Laminations
UI Core Lamination
Nickel Iron Core Laminations — high-permeability, low-loss signal work.

6. Materials & Steel

The starting point for everything above. Pick the grade and we’ll tell you what it does to your losses, your punch dies, and your budget.

7. Capabilities & Processing

A core is only as good as the steps that make it. We do all of these in-house, which means one supplier owns the whole tolerance stack.

Not sure which one you need?

Most people aren’t, and that’s fine. Tell us the motor, the speed, the power, and where it has to survive — or just send the drawing. We’ll come back with a material call, a lamination thickness, and a price. No obligation.
