I design for EMI shielding, insulation class, environmental protection, and the right IP 등급.

A peek inside the tech
I can pair a brushless DC frameless motor 또는 permanent magnet synchronous motor frameless with your load. I tune PID 컨트롤러 gains and set field‑oriented control. I shape the inertia match. I map performance curves. I verify 반복성. I check noise reduction 그리고 vibration reduction. I plan thermal resistance paths. I guard with EMI shielding.
I test in 클린룸, 진공, IP67, IP65, heat, and shock. I set operating temperature range. I note mean time between failures (MTBF). I align to motor insulation class.
I choose the right encoder resolution for your job. A robot joint needs high bits. A conveyor needs fewer counts. A gimbal motor needs Sin/Cos for smooth blend. A lab tool may need BiSS for noise immunity.
