Description

The T-Motor F40PRO IV represents a refined generation of FPV racing motors, building upon the legacy of the F40 PRO series with a 9% weight reduction. Its engineering focuses on minimizing rotational mass and internal energy loss through optimized pinholes and high-grade silicon steel laminations, resulting in faster throttle response and improved efficiency.

Designed for the demands of competitive racing and aggressive freestyle, the motor maintains stable performance and high-temperature tolerance during sustained full-throttle maneuvers. The integration of a titanium shaft and custom silicone lead wires ensures durability against physical impacts and electrical stress, providing a reliable foundation for high-speed builds.

Key Features

  • High-Performance 1950KV Winding: Delivers rapid acceleration and top-end speed suitable for 5-inch racing quads on 4S-6S power.
  • Advanced Lightweight Construction: Weighing only 30.8 grams, it enhances quadcopter agility and flight time.
  • Durable Titanium Shaft: The 4mm shaft provides increased strength and resistance to bending in crashes.
  • Optimized Magnetic Circuit & Stator: 12N14P configuration with precision silicon steel reduces iron losses and improves thermal performance.
  • High-Temperature Tolerance: Engineered components withstand the thermal loads of peak 42A current draws.
  • Premium Silicone Lead Wires: 20AWG wires with 150mm length offer flexibility and reliable high-current connectivity.
  • Direct Propeller Compatibility: Designed for optimal performance with T-Motor T5146 and T5147 FPV propellers.

Applications

  • 5-inch FPV Racing Drones: Built for competitive racing circuits requiring maximum acceleration and top speed on 4S-6S.
  • 5-inch Freestyle Quadcopters: Provides the explosive power and precise control needed for technical tricks and proximity flying.
  • High-Performance 5-inch Builds: Ideal for pilots seeking a lightweight, durable motor for aggressive flying styles.
  • Builds with T-Motor Ecosystem: Optimized for use with T-Motor F55A PRO II ESCs and T5146/T5147 propellers.

Frequently Asked Questions

What is the recommended ESC for the T-Motor F40PRO IV 1950KV motor?

T-Motor recommends using their F55A PRO II 4-in-1 ESC for optimal performance. The motor's peak current draw is 42A, so any high-quality ESC rated for at least 45-50A continuous current per motor on 4-6S LiPo is suitable.

What size propellers are compatible with the F40PRO IV motor?

This motor is engineered for 5-inch propellers. T-Motor specifically designed it for optimal performance with their T5146 and T5147 FPV propeller series. It can also run other standard 5-inch bi-blade or tri-blade props within reasonable current limits.

Can I use this motor on a 6S LiPo battery?

Yes, the T-Motor F40PRO IV is fully rated for 4S to 6S LiPo battery operation. Its 1950KV winding and robust construction are designed to handle the increased voltage and RPM, providing higher top speeds and thrust on 6S setups.

What is the shaft diameter and material?

The motor features a durable 4mm diameter shaft made from titanium. This provides superior strength and resistance to bending compared to standard steel shafts, which is critical for surviving crashes in FPV racing and freestyle.
