A linear induction motor produces straight-line thrust with no gears, no contact and no wheels to grip. We take your requirement, turn it into a working design, and prove it with modelling, FEA and route simulation before any metal is cut.
Understanding the requirement
Every design starts from a clear brief. We work through what the motor actually has to do:
- the mass to be moved and how fast it needs to go;
- the acceleration and running distance;
- the space available and the power supply on hand.
We also choose the layout early. A single-sided motor runs along a steel track, and a double-sided motor grips a thin plate between two halves. Each suits different jobs, so we settle this at the start.
How it works
Think of an ordinary electric motor unrolled and laid out flat. Instead of spinning, its magnetic field sweeps along the track in a straight line and pulls the moving part with it. There are no wheels driving the load and nothing to wear against a surface.
We size the motor to deliver the thrust and efficiency you need within the space and power you have available.
Proving the design
Before we commit to a design, we check it with detailed simulation (FEA). This confirms the thrust and forces the motor will actually produce across its working range, so the numbers you receive are ones we have tested rather than simply assumed.
Simulating the real journey
A motor that copes with a single peak can still struggle over a full journey. We simulate the whole route, including speeds, gradients and repeated cycles, so we know the design holds up in real use and not just on paper. Because the drive works without gripping a surface, its pulling power is unaffected by rain, ice or steep gradients.
Keeping it cool
Heat, more than anything else, sets the true limit on what a linear motor can deliver. We check that the design stays within safe temperatures for both continuous running and short bursts of extra effort. If it runs too hot, we adjust the design rather than hope for the best.
Matching the drive and power supply
The motor and the electronics that run it are one system, so we design them together. We make sure the drive and your available power supply can deliver the performance the motor is designed for, right across its speed range.
