Vector Technics 4006 Brushless Motor

The Vector 4006 is a brushless motor for industrial and enterprise UAV powertrains, offered in 400KV and 440KV windings and built around a 4006 stator for airframes needing steady, efficient thrust.

Key features

• Rated for a 6S LiHV power system: 24V at 400KV, 22-25V at 440KV.
• Handles up to 10A continuous current and 250W continuous power over a 180-second run.
• Torque constant of 0.030 Nm/A at 4800rpm (400KV) or 0.0329 Nm/A at 5100rpm (440KV) for efficient, high-torque operation.
• Power density of 2.72 W/g rated and 5.11 W/g maximum (400KV), or 3.14 W/g and 5.96 W/g (440KV), keeping the motor light for its output.
• Lightweight design at 67g, suited to industrial and enterprise multirotor platforms rather than small FPV frames.

Specifications

• Stator size: 4006
• KV: 400KV or 440KV
• Weight: 67g
• Continuous current: 10A (180s)
• Continuous power: 250W (180s)
• Input voltage: 6S LiHV (24V; 22-25V for 440KV)

Match the motor to an ESC and propeller rated for its continuous current and power figures, and confirm the airframe's mounting pattern before installation. Running it below its rated 180-second current and power window helps keep the winding temperature in check on longer flights.
