Product overview
The CKESC Breeze 80A-M FOC from Nanchang ChangKong Technology Co., Ltd. is a UAV electronic speed controller using FOC motor drive. Its 76 × 33 × 16 mm body weighs 76 g including wiring. Connections comprise 150 mm power leads, 100 mm three-phase motor leads, a 550 mm signal lead and an 80 mm data feedback cable. PWM control accepts a 3.3–5 V signal level, with a throttle travel range of 1000–2000 µs. No BEC is included.
The controller carries an 80A 6~14S specification, while continuous operating current is separately rated at 40 A with specified heat dissipation and peak current at 100 A for 3 seconds. Its ingress rating is IP54, and operating ambient temperature is −20 to +65°C. Above 120°C, maximum output power gradually decreases, potentially to 40% of full-throttle power, then recovers as temperature falls; the temperature protection point is separately specified as 125°C. Stall protection attempts a restart, but a stall at high throttle may damage the controller.

| Overcurrent protection | Limits peak current to prevent it exceeding the limit. |
| Overload protection | Limits maximum throttle to protect the propulsion system.When excessive motor load is detected. |
| Signal-loss protection | Gradually reduces output power, rapidly lowers throttle below 40% within 3 seconds, then slowly reduces throttle until the motor stops.After signal loss lasting 500 ms. |
| Battery protection | Gradually limits output throttle to prevent battery overdischarge. |
