Product Description

ZTW ZX 50A FOC ESC 6-14S Industrial Brushless Motor Controller for UAV and eVTOL

FOC Technology for Industrial-Grade Efficiency

The ZX 50A is the entry point to ZTW's FOC (Field-Oriented Control) industrial ESC series, delivering smoother torque, higher efficiency, and lower noise than conventional BLDC ESCs — ideal for lightweight commercial UAVs, inspection drones, and small eVTOL platforms.

20A Continuous / 50A Burst with FOC Precision

Rated at 20A sustained and 50A peak on 6-14S LiPo, this ESC leverages FOC to maximize motor efficiency across the entire RPM range, extending flight time and reducing thermal stress on both ESC and motor.

Parameterless Programming — Plug and Play

Featuring auto motor parameter identification, the ZX 50A eliminates manual throttle calibration and timing tuning. OEM integrators can deploy faster with consistent performance across production units.

Ultra-Compact 73g Form Factor

At just 61×34×19.5mm and 73g, this is the smallest ESC in the ZX industrial line. 14-gauge power and motor wires (55mm) keep the installation footprint minimal for weight-sensitive airframes.

UART & CAN Bus with Telemetry

Customizable UART and CAN bus interfaces enable real-time telemetry — current, voltage, temperature, and RPM — integrating seamlessly with industrial flight controllers for mission monitoring and predictive maintenance.

Field-Upgradable Firmware

Upgrade firmware in-field via the communication interface, ensuring access to the latest FOC algorithm refinements, protocol support, and reliability enhancements without hardware replacement.

Splash-Proof Industrial Build

Splash-proof construction protects against moisture, dust, and particulates, making the ZX 50A suitable for outdoor commercial operations in demanding environmental conditions.
