dynAIMx®

dynAIMx®

Due to the high power density and efficiency and the good dynamic features, the synchronous motor concept is used in a wide range of applications. Efficient control methods for synchronous motors require, however, a rotor position feedback. Usually, this is realized by a position sensor (or short sensor) mounted at the end of the shaft. With dynAIMx® we offer a software position sensor, which you simply integrate into your consisting controller code.

Advantages

The application of dynAIMx® provides numerous advantages over the operation with a rotary sensor.

General advantages of sensorless control compared to control with position sensor:

You gain additional space and can use a second open shaft end.

The calibration, assembly and alignment of the position sensor as well as the costs for the sensor, cable, plugs, supply and evaluation circuit are no longer required.

Sensor-related limitations for the use of your drive in terms of temperature, vibration, pressure and operation in liquids are no longer relevant. And even within the old limitations the failure probability of the drive system is reduced because the most unreliable component is now eliminated.

Advantages by the use of dynAIMx® compared to other sensorless methods:

DynAIMx® operates throughout the entire speed range – including standstill – with full performance.

DynAIMx® can be implemented on your system within a few days, there is no development risk.

There is no tuning and no filter parameters, only physical motor-parameters can be set.

DynAIMx® achieves more torque, more dynamics, less noise and less computational load than conventional methods, and does even allow “difficult” machine types to be operated without position sensor.

Fields of application

DynAIMx® is a flexible library that can be used in a variety of applications:

  • Industrieller Roboterarm

    In industrial automation the focus lies on dynamics, which is not limited by dynAIMx® compared to other sensorless methods.

  • Dentalinstrumente

    In medical technology robustness and space are required.
    In these regards dynAIMx® is superior to any sensor solution.

  • Waschmaschine

    In the consumer sector there is extreme price pressure. Including dynAIMx®
    only takes a small part of the computational capacity of a microcontroller and
    does therefore most likely not require a processor change.

  • Elektroauto

    In traction applications maximum torque is required at a standstill, here dynAIMx® is clearly superior to other sensorless solutions.

 

Features

We deliver dynAIMx® to you as a pre-compiled library, which you include into your consisting code. Using the interfaces shown in the figure, parameters can be set and read from dynAIMx®. DynAIMx® itself does not interfere with your control and only provides the rotor position
