Custom BLDC Winding Solutions: KV, Kt & Torque Matching for OEM R&D
Custom BLDC winding schemes for OEM R&D. Precise KV/Kt matching, optimized copper slot fill, and voltage platform scaling. Request custom electromagnetic profiles.
Engineering Challenges in Electromagnetic Matching
Standard off-the-shelf motor windings force engineering trade-offs during OEM product R&D:
Driver Thermal Overload: Mismatched KV values force ESCs to operate at extreme duty cycles, causing rapid driver overheating.
Insufficient Low-End Torque: Incorrect torque constant (Kt) causes sluggish response and current spikes under high load conditions.
Voltage Platform Bottlenecks: Off-the-shelf windings cannot adapt when migrating battery platforms (e.g., 24V to 48V/72V).
Technical Comparison
Feature | Off-the-Shelf Standard Windings | MYSUN POWER Custom Windings |
KV / Kt Precision | Fixed standard ratings (±10% variance) | Custom-calculated KV/Kt matched to exact RPM/Voltage |
Slot Fill Factor | Standard machine fill (~35–40%) | High-density precision winding (>55% copper slot fill) |
Thermal Margin | Class B/F Insulation (130°C–155°C) | Class H 180°C High-Temp Enamelled Wire |
Key Specifications & Customization
