What is a frameless motor?
- It is two parts. A stator и rotor.
- No case. No shaft. No bearings.
- You put it right in your machine.
- It is прямой привод. It has zero backlash.
- It can be BLDC или PMSM.
- It can be slotless или distributed winding.
- It can have a hollow shaft. You can pass wires through.
- It can have high pole count for smooth feel.
- It brings high torque density in a compact motor design.
- It cuts weight и size. It saves космос.
What is an encoder?
- It is a tiny eye. It tells position и скорость.
- It can be абсолютный. You know spot right on power up.
- It can be инкрементный. You count steps.
- It can be optical, magnetic, или inductive.
- It can use Hall effect sensors.
- It can send digital или analog output.
- It can talk BiSS, SSI, Sin/Cos, или quadrature A/B/Z.
- It drives closed loop control с PID или FOC.
Why put them together?
- You get точное позиционирование и повторяемость.
- You get high dynamic response with quick start and stop.
- You get low cogging torque. Motion feels silky.
- You cut mechanical complexity. No belts. No gear lash.
- You improve thermal management. Heat flows to your frame.
- You raise reliability и MTBF.
- You hit tight spaces с space-saving motor kits.
I build this into smart actuator components. I pair servo motor frameless kits with encoder feedback systems. I size them with performance curves, torque speed characteristics, continuous torque, peak torque, torque constant (Kt), back EMF constant, winding resistance, winding inductance, rotor inertia, thermal resistance, и operating temperature range. I design for EMI shielding, insulation class, environmental protection, and the right Степень защиты IP.
The promise to you
- I attract your eye. Small motor. Big push. Clean look.
- I point out the need. You want точность. You want безопасность. You want скорость.
- I meet the need. I build to your spec. I test. I prove.
- I position my product as your fix. I make it fit. I make it work. I back it up.

A peek inside the tech
I can pair a brushless DC frameless motor или permanent magnet synchronous motor frameless with your load. I tune ПИД-регулятор gains and set field‑oriented control. I shape the inertia match. I map performance curves. I verify повторяемость. I check noise reduction и vibration reduction. I plan thermal resistance paths. I guard with EMI shielding.
I test in чистая комната, вакуум, 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.
I match the stack to your контроллер on EtherCAT, CANopen, или PROFINET. I route cables through a hollow shaft. I mount to your frame with simple bolts. I set cable lengths и connector options that fit your panel.
