MAD FOC IGBT 30A 80-440V Drone ESC

Overview

The MAD AMPX 30A 80-440V ESC is a high-performance electronic speed controller (ESC) designed for heavy-lift multirotors, UAVs, and other demanding applications. Utilizing IGBT three-phase full-bridge inverter technology, this ESC supports sensor-less Field-Oriented Control (FOC) for precise motor performance. With a peak output current of 75A and support for input voltages from 80V to 440V, this controller is built for high-power propulsion systems. Advanced thermal management, current limiting, and overvoltage/undervoltage protections ensure stability and longevity, making it ideal for professional and industrial drone applications.

ESC Protection Mechanisms

• Undervoltage Protection: Automatically stops output when voltage drops below the threshold.
• Overvoltage Protection: Protects against voltage spikes; allows controlled deceleration in case of motor-induced overvoltage.
• Throttle Detection: Monitors throttle signal and prevents unintended acceleration due to loss of control.
• Sensor Zero-Point Detection: Ensures correct phase alignment upon startup.
• Overtemperature Protection: Dynamically adjusts current and output power to prevent overheating.

Throttle Calibration Steps

1. Connect the ESC PWM signal to the receiver.
2. Turn on the remote control and set the throttle to maximum.
3. Power on the ESC, wait for calibration tones.
4. Set the throttle to the starting position and confirm calibration tones.
5. ESC saves max and min throttle settings.
6. Power off the ESC.
