3RACING TaiChi 540 BMTC-A175S/BL 17.5T Sensored Racing Motor  [BMTC-A175S/BL]

Technical Summary: 3RACING TaiChi 540 17.5T Sensored Motor

The 3RACING TaiChi 540 17.5T Brushless Sensored Motor BMTC-A175S/BL is developed with a focus on predictable commutation and linear throttle response for competitive applications. It supports detailed ESC tuning and setup work to extract consistent lap times from 1/10 scale platforms.

Sensored Feedback and Control Characteristics

This sensored motor delivers stable low RPM torque that assists in precise launches and corner exits. The sensor signal allows advanced ESCs to synchronise rotor position accurately, minimising cogging and improving driveability.

Performance Envelope and Application Notes

The 17.5T winding is selected to provide a usable balance between thermal efficiency and acceleration. It is suitable for club level and national racing where drivability and predictable power delivery are more valuable than maximum RPM.

Setup Recommendations for Racers

Use a sensored ESC with configurable timing, throttle curves, and motor advance. Begin with conservative timing, verify sensor alignment, and monitor motor temperature under representative run conditions. Fine-tune gearing to control peak load and maintain consistent thermal behaviour.

For competitors focusing on setup and repeatability, the 3RACING TaiChi 540 BMTC-A175S/BL offers the sensing fidelity and control needed to refine vehicle balance and lap consistency.
