Product overview

AM controller

The AM is the lightest standard member of the ESC3 controller family. It can be used in a wide range of applications, especially in industrial and automotive. Using the most modern technologies, it achieves extreme dynamics and maximal efficiency. It implements smooth start and regenerative braking, all within minimum dimensions. The AM controller is capable of driving all common types of electric motors.

Controller editions (housing variants)

AM controller may come in different housing variants, called editions. Each edition provides different levels of protection and thermal management. The following editions of the AM controller exist:

• Standard edition. Aluminium enclosure, waterproof (sealed). Best protection and thermal conductivity.
• Raptor Fan. Optimized for airborne applications with active air cooling.
• Raptor Flat. Optimized for airborne applications.

Product variants

The AM controller is a very versatile product. To match all specific requirements, multiple properties can be adjusted, so many variants exist. Different variants are denoted by different MPN (Manufacturer Part Number).

The MPN consists of several parts:

• Base name -- denotes compatible firmwares (e.g. AM-felix, AM-raptor, AM-serpent)
• Assembly code -- defines voltage/current rating, communication interfaces, motor sensors, and internal HW configuration
• Finish variant -- defines signal/power wiring, housing, and enclosure

Base names and compatible firmwares

Base name	Target application	Compatible firmware
AM-titan	All available applications, used with samples	LYNX, FALCON, OPHION, ECHO
AM-felix	Ground vehicles (e-bikes, motorbikes, scooters)	LYNX
AM-raptor	RC models (drones, planes, boats)	FALCON
AM-serpent	Industrial electric drives	OPHION

MPN: esc3-am2a_08dsh0820-800_PC901-A10E1

Equipped with FALCON firmware. Intended for aircraft vehicles (drones, high-end RC models). It uses latest generations of the mosfets to deliver more current.

Built-in LED status indicator

The AM controller has a built-in LED which indicates the state of the control program:

1. Bootloader -- LED lights very briefly while firmware version and checksums are checked. If the controller remains in this state for more than a few seconds, there is a firmware problem. Try updating the firmware.
2. Main program -- LED is lit while the Driver initializes.
3. Driver -- the motor control part of the firmware:
   • LED off -- Driver successfully initialized, motor can be driven
   • LED on solid -- Driver status word is non-zero, a high priority limiter may be active. LED turns off after 2 second timeout when condition passes.
   • LED blinking -- an error occurred. LED blinks 16 times, pauses, then repeats. Each blink represents one bit of the error word (long blink = 1, short blink = 0, LSB first).
