Quanteon QPT 4720 380KV Brushless Motor

The Quanteon QPT 4720 380KV is a 12N14P brushless outrunner for heavy-lift and industrial multirotors, rated for quadcopters of 6–16 kg all-up weight. Its low KV is matched to 13–18 inch props on 6S to 12S LiPo, making it a fit for cinema-camera and LiDAR lifters, inspection and security platforms, delivery quads carrying 3–5 kg payloads and efficiency-focused VTOLs.

Key features

• 8 kg rated maximum thrust per motor, or 32 kg across a quad.
• Bench-tested on 6S with a 15 × 7 × 3 prop: about 4.97 kg of thrust at full throttle, drawing 46.5 A at 7,422 RPM, with motor efficiency peaking near 82%.
• N52SH magnets and a low 1.5 A no-load current.
• 14 AWG silicone leads, 317.8 g including cable.

Specifications

• KV: 380
• Stator: 47 × 20 mm
• Configuration: 12N14P
• Operating voltage: 6S–12S LiPo
• No-load current: 1.5 A
• Max thrust: 8 kg
• Full throttle on 6S, 15 × 7 × 3 prop: 4.97 kg, 46.5 A, 7,422 RPM
• Recommended props: 13–18 inch, 15 or 16 inch carbon for best efficiency
