Motor load diagnostics module (MLD)

Automated systems require continuous recording of the motor load. They also require qualified technicians who understand the measured values and can respond appropriately. Our didactics module helps to train them to do so in a practical way.

Learn how to measure and influence motor load in a clear and practical way

Teaching aid helps to understand the loads on an AC asynchronous motor
Practical didactics module: motor load diagnostics (MLD)

For operators of modern automated production plants, it is imperative to ensure process safety if the prescribed throughput rates are to be observed. Therefore, operating personnel must always be informed of exactly which loads their AC asynchronous machines are currently being subjected to. This enables the qualified technicians to implement appropriate measures in a timely manner to resolve discrepancies as quickly as possible.

Training in the reliable interpretation and influencing of motor load is a worthwhile investment: Qualified electronics professionals (MT, EBT, EMA, EAT, EAFT, EGS) help to prevent costly malfunctions.

Didactics module for practical learning at a high level

Our didactics modules for electromechanics with real, proven equipment guarantee learning at a high level as part of subject area 8 "Selecting and integrating drives." The motor load diagnostics (MLD) teaching aid set, for example, provides the opportunity to safely replicate the loads on an AC asynchronous motor, thus making them easier to understand.

The motor's direction of rotation can be easily changed using two 24 V inputs. The module also has an additional input, with which the prospective experts can evaluate the data from the motor thermistor directly. Motor management also supports the simple calculation of electrical parameters such as current, voltage, and power.

The motor load diagnostics module involves two pieces of electronic equipment:

  • Electronic load relay with the functions clockwise/counterclockwise rotation, electronic motor protection, and emergency stop as direct motor control
  • Motor management relay for overload and underload monitoring in drive machines
