TMOTOR P1604 Brushless Racing Motor – Aluminium Rotor Design for Reliable Power

The TMOTOR P1604 brushless motor delivers the consistent thrust and thermal stability needed for competitive racing drones and crossing machines. Its aluminium-clad rotor helps dissipate heat and resist damage during extended high-throttle runs. Available in two KV ratings – 2850KV (4-6S) and 3800KV (3-4S) – this motor lets racers match voltage and prop load for their specific setup. Whether you are building a lightweight freestyle quad or a high-speed cinewhoop, the P1604 provides reliable, repeatable performance without unnecessary weight or complexity.

Features and Construction

The P1604 is designed with a durable aluminium-clad rotor that improves thermal management during aggressive flying. The included mounting hardware makes installation straightforward.

Aluminium-Clad Rotor

The rotor features an aluminium cladding that aids heat dissipation. This helps maintain consistent performance and extends the motor's usable lifespan during demanding racing sessions where thermal build-up can degrade power output.

Two KV Options

Choose between the 2850KV variant (optimised for 4-6S LiPo batteries) for higher RPM with larger props, or the 3800KV variant (optimised for 3-4S) for lighter setups. Both options give you flexibility to fine-tune your drone's thrust-to-weight ratio.

Complete Mounting Kit

Each motor comes with four M2x5 screws, four M2x8 screws, one washer, and one locking shaft screw. This ensures you have the right hardware for various frame thicknesses and mounting patterns.

Uses and Placement

The P1604 is built for racing and freestyle drone applications where reliability and light weight are critical.

Racing Drones

With its compact 16mm stator size and two KV choices, the P1604 suits 3- to 5-inch racing quadcopters. The aluminium rotor helps maintain power during tight laps and repeated punch-outs.

Crossing Machines

For crossing-style builds that prioritise acceleration and manoeuvrability, the P1604 provides the responsiveness needed for quick directional changes. The rotor's heat resistance keeps performance stable over longer flights.

FPV Freestyle

Freestyle pilots can benefit from the motor's consistent throttle response and thermal resilience during acrobatic moves like power loops and inversions. The 2850KV variant works well with 4S batteries for a balanced freestyle setup.

Benefits and Buying Value

The P1604 offers practical advantages for racers and builders seeking a reliable, affordable motor without proprietary parts.

Thermal Resilience

The aluminium-clad rotor reduces the risk of magnet demagnetisation caused by heat – a common failure mode in high-kV motors. This adds a layer of durability that helps motors last through multiple rebuilds.

Simple Compatibility

With standard M2 mounting and a compact 16mm stator, the P1604 fits most 3- to 5-inch frames. The included locking shaft screw prevents the bell from loosening, reducing vibration and potential crashes.

Cost-Effective Performance

By offering two KV variants in a single product range, TMOTOR allows you to try different builds without buying entirely new motors. The bundled hardware also saves you from sourcing screws separately.
