IMS / Microprocess

This product is primarily intended for R&D engineers working on motors and robotics, as well as engineers responsible for the design and evaluation of EV/HEV motors.
It is also widely applicable to quality control departments handling inspection of magnetized products, designers evaluating magnetization accuracy of magnetic encoders and rotary angle sensors, and developers of magnetic application products such as smartphones, speakers, and VCMs.

From the research and development phase to mass production quality control, it is designed for all environments where accurate measurement and evaluation of magnetic fields are required.

This system can be used for magnetization quality inspection and lot control of motor rotors and magnets, as well as for magnetization evaluation of EV/HEV motors and comparison with simulation results.
It also supports evaluation of magnetization accuracy for magnetic encoders and rotary angle sensors, as well as demagnetization testing and defect analysis (such as phase deviation and magnetization non-uniformity).

The system supports both rotational and linear measurements, allowing a wide variety of workpieces to be measured with a single unit, including SPM rotors, IPM rotors, outer rotors, VCMs, disk magnets, flat magnets, and solenoids.
Measurement data can be visualized in various formats, such as 2D graphs, 3D graphs, contour maps, and vector maps, and can also be directly analyzed in Excel.

[Zero Physical Error with One-Chip 3-Axis Measurement]
A unique design integrates X, Y, and Z sensing elements on a single chip, eliminating positional misalignment found in conventional multi-chip systems and enabling accurate magnetic vector measurement at the same point.

[Automatic Magnetic Center Detection (Patented) – Repeatability ±0.02 mm]
The system automatically detects the sensor’s magnetic center and aligns it to the mechanical origin, removing manual adjustment and ensuring consistent results regardless of the operator.

[Automatic Angular Correction (Patented) – Accuracy ±0.2°]
Probe angle misalignment is automatically detected and corrected, ensuring precise sensor orientation. Correction is applied automatically even if the installation angle changes.

[Measurement Profiles for Easy Reproducibility]
Measurement conditions, positions, and probe settings can be saved and instantly recalled, reducing operator dependency and improving efficiency.

Our magnetizing equipment is designed for production engineers and R&D designers responsible for the magnetizing process of magnets used in motors and sensors. It is ideal for EV/HEV motor manufacturers working with high-coercivity magnets such as neodymium, production departments considering new or updated magnetizing equipment, and quality control staff seeking to stabilize magnetizing quality. It also suits R&D design teams that lack in-house equipment and wish to outsource the magnetizing of prototypes or small lots.

The equipment is used in post-assembly magnetizing processes, where high-coercivity magnets such as neodymium are fully magnetized after being assembled into a rotor. Capacitor-discharge pulse magnetizing generates an instantaneous strong field unattainable with DC power supplies, achieving reliable saturation magnetizing. Magnetizing yokes are designed and manufactured to match each customer's workpiece shape, number of poles, and required field strength, covering everything from IPM and SPM rotors to special arrays. For teams without dedicated equipment, our contract magnetizing service handles prototypes and small lots — verify magnetizing quality with a trial before investing in equipment.

[High-efficiency yoke design via 3D transient response analysis]
We simulate the time-varying magnetic field during magnetizing in 3D to optimize yoke geometry and windings. By concentrating the field efficiently with no waste, we achieve reliable magnetizing with less input energy.

[Integrated in-house design of power supply and yoke]
Since we design and manufacture both the power supply and the yoke, we can propose optimal combined magnetizing conditions, maximizing magnetizing quality.

[High-field pulse magnetizing by capacitor discharge]
Instantaneous discharge of large current stored in capacitors generates a strong field capable of saturation-magnetizing even high-coercivity magnets such as neodymium.

[One-stop from magnetizing to measurement]
Magnetizing quality is quantitatively evaluated with our own 3D magnetic field analyzer, MTX-7R, completing "design → magnetizing → measurement" within a single company.
