SWD is a world pioneer in bonded lamination stacks — an electromagnetic and electric core component of every high-performance motor. More torque, efficiency and precision. Less weight and waste. From idea to industrialization.
Series-proven — 10,000,000+ bonded segments produced·World pioneer in bonded lamination stacks·More than three decades of Swiss stator & rotor expertise
Payload, footprint, energy budget — in almost every new robot, the drive is the limit. And most drives still start from a full-circle, interlocked lamination stack that compromises in torque, efficiency and power — and in assembly steps. That's the wrong place to compromise.
Instead of stamping a full circle, we build the stack from precisely fitted segments. Higher copper fill, cleaner magnetics, near-zero scrap.
Our bonding technology replaces welds and interlocks — no short circuits between laminations, lower losses, higher efficiency.
We deliver the process and the technology. Prototype at SWD, scale at SWD, or run the technology inside your own factory.
Tighter tolerances, cleaner magnetic paths, higher fill factor. Same envelope — measurably more torque and control.
Segmented layouts reduce material use and give more design freedom. Better for runtime, thermals and total cost.
Material choice, tooling, process, machine, data — coordinated by one team from first sketch to series ramp.
Wherever a motor needs more torque, higher precision or less weight in the same envelope — the lamination stack is where we start.
A manufacturer of high-performance drives for delta pick-and-place robots needed highly precise, intricate lamination stacks. Through precise baking, honing and grinding, SWD hit the tightest required tolerances — for robots that run faster and more accurately.
Most suppliers get the drawing, blur on tolerances 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?
