• Peak Current: 150A (10S)
• Max RPM: 13,000 RPM (10 Pole Pairs)
• IP Rating: IPX7 (Water-resistant)
• Communication Protocol: CAN
• Weight (without cable): 116g
• Working Temperature: -20°C to 50°C
• Compatible Motors: M10 KV100, M17 KV100/KV110, M20 MINI KV110, M20 KV110
• Compatible Propellers: 29” to 40”

Key Features

1. Instant Throttle Response

• The fast motor acceleration and deceleration response allows the ESC to adjust rapidly (within 10ms) to throttle changes, ensuring precise control.

2. Optimized Heat Dissipation

• The ESC features a double-sided heat dissipation structure, reducing thermal resistance and maintaining a low internal temperature (only 15°C higher than the shell temperature).
• Improved cooling performance ensures stable operation under full load.

3. Advanced Protection Mechanisms

• Hardware Self-Check: Automatically detects hardware faults before flight to reduce failure risks.
• Short Circuit & Overcurrent Protection: Prevents damage from electrical faults.
• High Voltage Protection: Ensures stability even at 60.9V max input.
• High Temperature Protection: Prevents overheating failures.

4. Electric Modularity & Easy Maintenance

• Independent modular design allows easy replacement of individual components.
• Secure wiring system prevents accidental disconnections.
• Quick assembly and disassembly using simple tools.

5. CAN Communication Interface

• Supports firmware updates via CAN.
• Enables real-time system monitoring and enhances flight control communication.
• Improves black-box data logging for enhanced failure analysis.

6. PWM Control & Digital Throttle

• Supports PWM input (200-2000µs)
• Frequency Range: 50-450Hz
• Idle RPM: Minimum 300 RPM, configurable via software.
• Max RPM: 5000 RPM, configurable via software.

ESC Protection Mechanism

The MAD FOC 120A ESC incorporates an intelligent self-diagnostic system and LED indicator patterns to troubleshoot potential issues:

Issue	Cause	Solution
Motor does not turn after unlocking	Throttle signal below 1100µs	Set idle throttle to 1100µs-1180µs
Motor “beeps” every 15 seconds	Incorrect/missing PWM signal	Check throttle cable connection
Motor enters protected state	High throttle detected at startup	Reduce throttle before starting
Motor does not respond	Power-on self-test failure	Check battery voltage & connections
Short circuit detected	Overcurrent protection activated	Inspect motor & wiring
