Frequently Asked Questions
Do you supply shaft machining?
Yes, we provide full CNC machining for shafts and back-irons to ensure perfect fit and concentricity.
Can you magnetize after assembly?
Yes, post-assembly magnetization ensures higher flux density and better pole-to-pole consistency.
What adhesive systems do you use?
We use high-temperature structural epoxies (up to 200°C) tailored to your specific environment.
What concentricity tolerance can you hold?
Our standard is ≤0.02mm TIR, but we can achieve tighter tolerances depending on the design.
Do you provide FEA support?
Yes, we offer magnetic field simulation and FEA analysis to optimize your rotor’s performance.
