By filling thermosetting epoxy resin, magnets are bonded inside of holes of Rotor cores.
Compared to the conventional bonding process, Magnet Mold™ has higher filling rate and shorter cure time.
Applying high precise mold enable to produce high efficiency Rotor Cores at low cost.
※Magnet Mold ™ is Mitsui High-tec’s Trademark.
The segment core is emitted from Dies with shape of one body core.
We stamp both Stator segment and Rotor cores together which improve the productivity.We also stamp integral Stacked Segment Core with in tool rotation producing high precision motor core.
Compared to previous segment core, Integral-Stacked Segment core reduce cogging torque by eliminating gap between each tooth.
Mitsui High-tec, Inc. holds a patent of the process of Integral-Stacked Segment Core.
Mitsui High-tec's technology related to ＭAGNET ＭOLD™ is protected by the following patents.
Additional patents are pending in Japan and elsewhere.
