T-MOTOR U7 - 490KV High-Efficiency Professional Motor

Industrial Efficiency and Smooth Flight Performance

The T-Motor U7 490KV is a high-torque and ultra-efficient motor optimized for professional multirotors carrying heavy camera equipment. Its 490KV rating is specifically designed to spin propellers between 15" and 18" with maximum efficiency, especially with 6S (22.2V) battery systems. Thanks to T-Motor's proprietary magnetic circuit design, it produces more thrust with less energy consumption than its competitors, maximizing your operational time.

U7 490KV Key Features

• U-Series Efficiency-Focused Design: The special stator structure and optimized magnet arrangement minimize energy loss (heat). This ensures that every milliamp from your battery is converted into maximum thrust.

• Dust and Water Resistance: With industrial-grade coatings and a semi-enclosed body structure, it operates reliably in harsh field conditions, dusty terrains, and humid environments.

• Japanese EZO Bearing Quality: Extra-large EZO bearings easily handle the axial load created by heavy propellers. This results in much quieter motor operation and eliminates the "Jello" (vibration) effect in video recordings.

• Precise Dynamic Balancing: Each U7 unit undergoes factory balancing with the highest precision. This reduces body vibration to zero, allowing the flight controller (FC) to operate much more stably and steadily.

• Aviation-Grade Copper Windings: High-temperature resistant windings up to 220°C and a handcrafted internal structure ensure the motor maintains its structural integrity even in the most demanding tasks.

Usage Recommendation:

For maximum efficiency and lifting capacity, it is recommended to use with T-Motor carbon fiber propellers of 16x5.4, 17x5.8 or 18x6.1 sizes. To control this motor, pairing it with a 40A-60A ESC (preferably T-Motor Flame or Air series) will ensure full performance.
