Product Overview
Linear Motor Flat Magnet Track
Linear motor flat magnet tracks are precision permanent magnet assemblies used as the magnetic secondary in linear motors, direct-drive stages, gantry systems, semiconductor equipment, CNC machines, automation platforms and high-speed transport systems. The track provides a stable magnetic field along a straight path so the coil primary can generate smooth thrust without mechanical transmission parts.
A typical flat magnet track includes NdFeB, SmCo or ferrite magnets, a steel or stainless backing plate, positioning fixture, structural adhesive, optional cover plate, potting or protective coating, and final magnetic inspection. By controlling magnet grade, pole pitch, polarity sequence, magnet height, air-gap field and assembly flatness, the track can support high thrust density, low cogging, stable positioning accuracy and long service life.
Ningbo Vanguard Technologies supplies customized linear motor magnet tracks according to motor force requirement, stroke length, pole pitch, working gap, temperature, corrosion environment and installation method. We support conventional N/S pole tracks, multi-row tracks, segmented long-stroke tracks, Halbach-enhanced tracks, protective cover designs, field mapping and batch inspection.
Whether you need prototype magnet tracks for linear motor development or mass-production magnetic rails for motion-control systems, Vanguard can provide sample assembly within 10-20 days after drawing, magnet grade, pole pitch and inspection requirements are confirmed.

Design Points for Linear Motor Flat Magnet Tracks
Linear motor magnet tracks must satisfy both magnetic performance and mechanical installation accuracy. During design review, Vanguard focuses on pole pitch, magnet grade, backing plate material, adhesive strength, track flatness, field uniformity, working gap, temperature and protection method.
For precision motion systems, magnet position and track flatness directly affect thrust ripple, air-gap stability and positioning repeatability. Field mapping and dimensional inspection are recommended for production validation.
Pole Pitch Match
Pole pitch, magnet size and polarity sequence are matched to the coil pitch and force target.
Field Uniformity
Magnet tolerance, spacing, surface field and working-gap field can be checked to reduce thrust ripple.
Mechanical Flatness
Carrier flatness, hole position, datum control and magnet height consistency help maintain a stable air gap.
Magnet Retention
Adhesive type, bonding area, cover plate, potting and handling protection are selected by load and environment.
Manufacturing & Quality Assurance
Our linear motor magnet track process includes incoming magnet inspection, backing plate inspection, surface cleaning, polarity and magnetization verification, fixture positioning, adhesive dispensing, magnet placement, curing, optional cover or potting, dimensional inspection, surface Gauss testing, field mapping and final packaging.

Yes. Surface Gauss testing, working-gap field scanning, polarity sequence checks and magnetic consistency reports can be provided depending on project requirements.
How do you protect magnets during operation?
We can use magnet coating, stainless cover, aluminum cover, epoxy potting, edge protection and suitable packaging depending on moisture, dust, impact and handling conditions.
What is the lead time for custom linear motor magnet tracks?
