Industrial backbone of heavy lifting
The asynchronous three-phase motor is the most widely built and used electric motor worldwide. Around 65–70% of all produced motors fall into this category. With power classes up to 2 MW, these motors form the backbone of industrial plants. Their robustness and reliability make them essential for high-availability drive systems, especially when combined with frequency converters for speed regulation and precise torque control.
In practical applications such as crane hoist motors in ports, however, several challenges arise. These include shaft bearing wear, burnout, incorrect speed and torque operation, and electrical stress during voltage peaks. These issues impact both operational availability and manufacturer warranty conditions.
Within this project, the motor was equipped with integrated sensors to monitor relevant parameters. Through a network infrastructure, these values can be accessed remotely, enabling predictive maintenance and the development of digital services. The technology can also be transferred to other industrial applications.
