Frequently Asked Questions

What is the primary application for the T-Motor AT4125 540KV motor?

The AT4125 540KV motor is specifically engineered for heavy-lift fixed-wing and VTOL (Vertical Take-Off and Landing) UAV platforms. Its 6S voltage rating and high power output (up to 2000W) make it suitable for commercial applications like aerial mapping, cargo delivery, agricultural spraying, and long-endurance industrial inspection where reliable, high-torque propulsion is critical.

What is the maximum voltage and power this motor can handle?

This motor is rated for a 6S LiPo battery system (nominal 22.2V). It can deliver a peak power of 2000W for bursts of up to 180 seconds. The corresponding peak current during this burst is 85A. For continuous operation, it is crucial to stay within thermal limits using appropriate propeller sizing and flight profiles.

What propeller size and ESC are recommended for this motor?

Propeller sizing depends heavily on the specific airframe and desired thrust-to-weight ratio. For a 540KV motor on 6S, large-diameter, low-pitch propellers (e.g., 18x6 or 20x8) are typical for fixed-wing applications to maximize efficiency. A high-quality 80A-100A Electronic Speed Controller (ESC) with robust BEC capabilities is required to handle the peak 85A current draw reliably.
