Product overview
The CKESC STONE 130A-M from Nanchang Changkong Technology is a brushless electronic speed controller for UAV propulsion. Its wired assembly measures 92 × 40.4 × 20.9mm and weighs 155g including wiring, with separate power, three-phase motor, signal and feedback leads for integration. PWM control accepts 3.3~5V input signals, while serial output supplies real-time voltage, motor speed, current, ESC temperature and debugging data. Motor rotation direction can be set through software. Shielded signal wiring and optically isolated signal input and output interfaces reduce interference.
The 6~14S controller supports 80A continuous operation with specified cooling and 130A maximum operation for 3 seconds. It has no BEC. Standard protection is IP54, with IP67 available by customization. Timing-adjustment firmware is standard; a fixed version is optional, and maximum-power mode can be enabled. Low-voltage protection is disabled by default but can be enabled by customization. High-voltage protection inhibits startup when supply voltage exceeds the permitted value. Failed starts trigger current limiting and automatic retries, while excessive motor load limits maximum throttle.
Above 125°C, maximum output power gradually decreases, potentially reaching 40% of full-throttle power; original power returns after cooling. Signal loss lasting 200ms initiates output reduction: throttle falls below 50% within 1~2 seconds, then decreases slowly until shutdown. During a motor stall in normal operation, the controller attempts a restart, although a stall at high throttle may damage the ESC. Throttle integration uses a 1000~2000us pulse range, a 300ms response time and a 50~500Hz refresh rate, with 100~400Hz recommended.
