The failure of a large drive is usually associated with lengthy downtimes and high costs. Timely detection of a critical condition and the correct action when a fault occurs increase the availability of the entire plant.
In this course you learn about the motors as a part of a complex drive system as well as the impact of environmental and operational conditions. You will be able to analyze damage scenarios, determine possible causes of damage and suggest appropriate corrective measures. You will also be able to make recommendations for preventive maintenance.
Regional field service technicians and employees in service control centers, service sales specialists, consultant engineers and promoters for LD motors.
The course is only available for employees of the divisions DF and PD. The list of participants will be checked by DF CS SD TCC before final invitations are sent out. Contact: Hans-Artur Steinborn.
