Magnetization Equipment IMS / Microprocess

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.
