Plain-English notes on how linear motors and eddy-current brakes work, the main types we build, and what a feasibility study needs from you to get started.
How we prove a design
Every machine is checked against your real duty before any metal is cut. We model the design, simulate the full route or work cycle, and confirm it runs within its temperature limits — so what we build matches the job it has to do.
Modelled and analysed
We size the machine and analyse how it will behave, exploring the options early rather than guessing.
Route simulated
The full route or work cycle is run in simulation, so speeds, force and timing reflect the real job.
Thermally checked
We confirm the machine holds within its temperature limits across the cycle, not just at a single point.
How a linear motor works
A linear induction motor is a rotary motor unrolled flat. Instead of spinning a shaft, it produces a magnetic field that travels in a straight line and pulls a metal plate along with it. There are no gears, no drive wheels and nothing touching. Because it does not rely on grip, rain, ice and steep grades do not cause the wheel slip that limits a friction drive.
Single-sided and double-sided
Linear motors come in two common arrangements. The right one for a project depends on the track, the space available and how the machine is mounted — neither is universally better.
Single-sided
One active face working against a metal plate. Simpler, lighter track — the common choice where the structure can carry the pull towards it.
Double-sided
Two faces working either side of a thin metal fin. The opposing pulls balance out, and it can deliver more force for a given track width.
How eddy-current braking works
A permanent-magnet brake slows a moving part using magnets and metal alone — nothing touches. It is smooth and needs no power to work, and there are no pads to wear out or fade. The braking effect grows with speed through the working range.
What a feasibility study needs
The more of the following you can supply, the sooner we can put realistic numbers to a concept. Treat these as guidance, not a fixed form — where anything is still provisional, just say so.
- The job: speeds, distances, stops and how often it runs.
- The load: mass to be moved, including the worst case.
- Targets: the force or acceleration you need, and any braking or holding requirements.
- Space and structure: how much room you have and how the machine can be mounted.
- Power: the electrical supply available on site.
- Environment: temperature and conditions the machine has to work in.
- Mounting preference, if any: motor carried on the vehicle, or built into the track.
