Better robots start with a better motor.
SWD is a world pioneer in segmented, bonded lamination stacks — the electromagnetic core of every high-performance motor. More torque and precision. Less weight and waste. From first idea to series production.

Robotics is becoming physical AI — and every robot needs a motor that is smaller, stronger and more precise.
Payload, footprint, energy budget — in almost every new robot, the drive is the limit. And most drives still start from a full-circle stamped lamination stack that wastes up to half the electrical steel and caps what the motor can do. That's the wrong place to compromise.
We rethink the lamination stack — so your motor can do more.
Segmentation
Instead of stamping a full circle, we build the stack from precisely fitted segments. Higher copper fill, cleaner magnetics, near-zero scrap.
Bonding instead of welding
Our EPS® and BPS® bonding processes replace welds and interlocks — no short circuits between laminations, lower losses, higher efficiency.
Full industrialization
We deliver the process and the machines. Prototype at SWD, scale at SWD, or run the line inside your own factory.
More performance through precision
Tighter tolerances, cleaner magnetic paths, higher fill factor. Same envelope — measurably more torque and control.
Less weight, less waste
Segmented layouts halve material use and cut mass at the joint. Better for runtime, thermals and total cost.
From idea to series, from one partner
Material choice, tooling, process, machine, data — coordinated by one team from first sketch to series ramp.

Not a stamping shop.
Your industrialization partner.
Most suppliers get the drawing and quote a part. We come in earlier — when you're still deciding whether the motor is even feasible. We co-engineer the stack with your team, and bring decades of expertise in material, tooling, process, machines and production data to bear on the same question: how do we make this real, in series, without compromising what makes it new?
