Product overview

The T-MOTOR Antigravity MN4004 KV400 is a UAV motor supplied as a set of two. Its ultra-thin, ultra-light construction incorporates a distinctive ventilation and cooling system. Each motor weighs 53g including wires and measures Φ44.35×19mm. The internal layout uses an 18N24P slot and pole configuration with a 40mm silicon steel lamination outer diameter, while the motor wires are 50mm long.

The KV400 motor operates with a 4-6S LiPo battery and has a phase-to-phase resistance of 359mΩ. No-load current is 0.2A at 22V, with a maximum current of 12A for 180s and maximum continuous power of 65W for 180s. The MN4004 also comes in a KV300 variant, with 452mΩ phase-to-phase resistance and a maximum current of 9A for 180s.
