Product overview
The CKESC ROCK 60A 18S from Nanchang Changkong Technology Co., Ltd. is a UAV motor-control component with PWM communication and software-selectable motor rotation direction. Its 90.4 × 36 × 18.5mm body and 112g weight including wiring define its installation footprint. Low-resistance MOS components handle power switching, while shielded signal wiring and optically isolated signal input and output interfaces address interference. The controller has an IP54 rating and no BEC, a configuration detail relevant to the aircraft’s power-system integration.
The electrical specification is 6–18S, with continuous operation rated at 30A under specified heat-dissipation conditions and a 60A maximum for three seconds. Throttle travel is 1000–2000µs, input signal level is 3.3–5V, and refresh rate is 50–500Hz, with 100–400Hz recommended. Low-voltage protection is disabled by default but can be enabled through customization. Other protections address excessive voltage, unsuccessful starts, stalls, overheating, current, overload and signal loss. A stall at high throttle may damage the ESC; above 120°C, thermal protection progressively reduces available power.

| High-voltage protection | Prevents motor startup.When supply voltage exceeds the permitted value. |
| Startup protection | Limits starting current and automatically retries startup.After an unsuccessful motor start. |
| Stall protection | Attempts to restart the motor after a stall, generally caused by external force.If the motor stalls during normal operation; a stall at high throttle may damage the ESC. |
| Overtemperature protection | Gradually reduces maximum output power, potentially down to 40% of full-throttle power.When temperature exceeds 120°C; original power returns after cooling. |
| Overcurrent protection | Limits peak current so it does not exceed the limit. |
| Overload protection | Limits maximum throttle to protect the propulsion system.When excessive motor load is detected. |
| Signal-loss protection | Progressively reduces output power, quickly lowers throttle below 50% within 1–2 seconds, then slowly reduces throttle until the motor stops.After signal loss lasting 200ms. |
