ZTW 3450KV 2-3S Sensorless 540 Brushless Motor 3.17mm Shaft 1/10 Scale - ZTW-2125121

The ZTW ZTW-2125121 is a 3450KV sensorless 540 brushless motor designed for 1/10 scale RC cars running on 2S or 3S LiPo power. Built around the standard 540 motor can format, it drops into a wide range of 1/10 scale electric RC cars that accept a brushless motor upgrade, making it a practical choice for replacing a worn brushed motor or stepping up to brushless performance for the first time. The 3.17mm motor shaft is a common diameter across many 1/10 scale pinion gears, so finding a matching pinion is straightforward.

Key Features

• 3450KV rating suits general bashing and sport driving on 2S or 3S LiPo — higher voltage delivers more top-end speed
• Sensorless design means no sensor wire is needed, simplifying installation and reducing wiring complexity
• Standard 540 can size fits the motor mount dimensions used across a wide range of 1/10 scale RC car platforms
• 3.17mm motor shaft is compatible with the majority of 1/10 scale pinion gears available on the market
• Brushless construction reduces wear compared to brushed motors, requiring less routine maintenance over time
