Overview

The RCInpower Bison 22.5-7 FPV Drone Motor is a high-performance brushless motor designed for FPV drone builds that demand strong structure, smooth operation, and efficient power delivery. According to the product images, this motor continues the design language of the earlier GTS V2 series while improving structural strength and crash resistance. It features a 22.5mm stator diameter, 7mm stator height, 12N14P configuration, a 4mm semi-hollow shaft, and a lightweight design of about 33g.

The Bison 22.5-7 uses a newly developed stator specification rather than a conventional 22xx or 23xx size, and it is equipped with 220°C single-strand enameled copper winding for strong and linear throttle response. RCInpower also highlights an optimized anti-vibration design and upgraded 4x11x4mm (694) bearings, intended to improve smoothness, durability, and bearing life. Available in 1800KV and 2500KV versions, this FPV motor suits different voltage platforms and flying styles.

Key Features

New 22.5-7 Stator Platform

This motor uses a 22.5mm stator diameter and 7mm stator height, setting it apart from more common 22xx and 23xx class motors. The design aims to balance output, responsiveness, and weight.

Improved Structural Strength

The image text states that the Bison series continues the GTS V2 design language while optimizing structural strength and improving crash resistance, making it better suited for demanding FPV use.

220°C Single-Strand Copper Winding

The stator uses 220-grade single-strand oxygen-free copper winding, which is presented as delivering very linear power output.

Optimized Anti-Vibration Design

RCInpower highlights an optimized damping and anti-vibration structure to reduce motor vibration and help extend bearing life.

Larger 694 Bearings

Compared with standard 4x9x4mm (684) bearings, this motor uses larger 4x11x4mm (694) bearings for improved smoothness and durability.

Lightweight Design

The product image shows the motor weight at approximately 33.07g, while the specification sheet lists 33g (with 3cm wire), indicating a design focus on keeping weight low while maintaining strength and power.
