Overview
VCI SPARK 3512 motor is available in 450KV and 800KV options for multirotor/UAV propulsion setups where consistent mechanical fit and published bench data are required. The series uses an M5 shaft and provides 16AWG silicone leads for power connection.
Key Features
- KV options: 450KV or 800KV
- 12N14P configuration with N52SH arc magnets
- M5 shaft, plus 4× M3 equally spaced mounting holes
- Ø45.6 mm outer diameter design with Ø35×L12 mm stator
- 16AWG silicone wire, 500 mm length
