Rotor FAQ
What rotor types can you manufacture?
We manufacture custom rotors including motor rotors, generator rotors, pump rotors, compressor rotors, turbine rotors, brake rotors, and custom profile rotors. All types are available in single-off and production quantities.
What materials are best for high-speed rotors?
Steel 4140 or 4340 is the best choice for high-speed rotors — excellent strength and fatigue resistance. Stainless steel 17-4 PH offers superior corrosion resistance while maintaining high strength. For aerospace applications, Inconel or titanium provide optimal strength-to-weight ratio.
Can you balance rotors for precision applications?
Yes. Dynamic balancing is available as a standard service. Rotors are balanced to ISO 1940 Grade G2.5 or G1 for precision applications. Balancing includes test run verification and certification.
What is the typical lead time for custom rotors?
Single-off custom rotors are typically completed within 3–4 weeks from quote approval. Production runs of 10+ units are usually completed within 4–6 weeks. Lead times depend on complexity and balancing requirements.
Can you manufacture rotors with custom slot profiles?
Yes. Custom slot profiles for motor and generator rotors are engineered to your specifications. We can manufacture complex laminated or solid rotors with custom slot geometry.
Do you offer dynamic balancing services?
Yes. Dynamic balancing is a core service. Rotors are balanced to ISO 1940 standards, tested at operating RPM, and certified. Balancing is included on all rotor manufacturing unless otherwise specified.
