Product overview
The CKESC Breeze 130A 14S FOC from Nanchang ChangKong Technology Co., Ltd. is an electronic speed controller for drone motors. It combines FOC drive with vfast observer technology and kinetic energy recovery. Its lightweight design measures 101 × 41 × 21 mm and weighs 165 g including wiring. The controller accepts a 6~14S supply and supports PWM and CAN communication with data storage. Serial control and output are customizable. It has no BEC, and its input signal level is 3.3~5 V.
The throttle pulse range is 1000~2000 us, with a refresh rate of 50~500 Hz and a recommended range of 100~400 Hz. Continuous operating current is 70 A with specified cooling; maximum operating current is 130 A for 3 seconds. Ingress protection is IP54, with IP67 customizable, and ambient operation spans -20~+65°C. Above 120°C, maximum output power gradually falls, potentially to 40% of full-throttle power, and recovers after cooling. Stall protection attempts a restart, but a stall at high throttle can damage the controller.
Electrical protection inhibits motor startup when supply voltage is below or above the permitted value. An unsuccessful start triggers current limiting and an automatic restart attempt. During operation, the controller limits peak current, restricts maximum throttle when excessive motor load is detected, and gradually limits output throttle to prevent battery overdischarge. After 500 ms of signal loss, output power begins to decrease; throttle drops below 40% within 3 seconds, then decreases slowly until the motor stops.
