Product overview
The CKESC Breeze 300A 18S FOC is a lightweight electronic speed controller for UAV motor control, using FOC drive and vfast observer technology. Its electrical specification is 300A 6~18S, with 300A explicitly rated as a three-second peak. The controller weighs 324g including connectors. Integration parameters include a 1000~2000us throttle range, 3.3~5V input signal level and a 50~500Hz throttle refresh rate, with 100~400Hz recommended. PWM and CAN communication are provided alongside data storage; serial control and output are customizable.
The controller has no BEC. Its stated ingress protection is IP54, with IP67 available through customization, and its operating ambient range is -20~+65°C. Protection functions address supply voltage, failed starts, stalls, current, overload and battery overdischarge. Above 115°C, maximum output power decreases gradually, potentially reaching 40% of full-throttle power before recovering after cooling. Signal loss triggers a staged reduction to shutdown. Stall protection attempts a restart, but a stall at high throttle can damage the ESC.
