Appcon Motor Control
Universal Sensorless PM-Motor Control Driver. Any Motor. Any Inverter.
Appcon Motor Control (AMC) is a motor control driver software library designed for controlling permanent magnet motors in a wide range of drive applications. The library can be integrated directly into a customer's firmware, enabling reliable motor control with or without a position sensor.
AMC is a software-only solution that eliminates the need for a mechanical position sensor by accurately estimating motor speed and rotor position while maintaining performance comparable to sensored Field-Oriented Control (FOC).
The technology behind AMC is the result of more than 20 years of industrial experience in sensorless control of PMSM drives, with implementations running in products manufactured in millions of units every year.
Designed for practical use in real products, AMC combines high performance, robustness, and ease of integration. Features such as automatic motor identification allow developers to configure the control quickly, even without deep expertise in motor control.
As a plug-and-play control module, AMC integrates directly into existing drive software architectures, enabling rapid deployment of advanced motor control capabilities.

AMC vs. sensored solution
| Encoder-based FOC | AMC (sensorless) |
|---|---|
| Position sensor (encoder/resolver) required | No sensor; motor acts as sensor |
| Additional hardware cost and wiring | Software-only, no extra hardware |
| Sensor reliability and environmental limits | Fewer failure points, robust |
| Performance depends on sensor quality | Performance parity with sensored FOC |
