Customized Rotor Cores for PMSM
Precision rotor cores, fully customized to your drawings – optimized for magnetic performance, mechanical strength, and high-speed operation
We specialize in manufacturing high-precision rotor cores for Permanent Magnet Synchronous Motors (PMSM), fully customized according to drawings provided by our clients.
The rotor core is a critical component that directly affects motor efficiency, torque density, and high-speed stability. Whether you are designing interior permanent magnet (IPM) or surface-mounted (SPM) rotors for electric vehicles, industrial servos, or high-speed applications, our rotor cores are engineered to meet your exact specifications.
We work closely with you to produce tailored solutions that integrate seamlessly with your magnet assembly and shaft coupling requirements.
Key Features & Benefits
Manufactured strictly based on client drawings – including outer diameter, inner diameter, stack length, magnet slot shape, and ventilation holes.
Achieving tolerances as tight as ±0.001 mm for critical dimensions, ensuring balanced high-speed rotation.
Supports non-oriented electrical steel (M470, M600, M800, M1300) or laminated silicon steel for optimal magnetic flux.
Accurate magnet slot dimensions for interference fit or adhesive bonding of permanent magnets.
Interlocking, welding, or adhesive bonding – chosen based on your mechanical and thermal requirements.
Production follows ISO 9001 & IATF 16949 standards with 100% dimensional inspection and optional dynamic balancing.
