This course is aimed at configuration engineers and sales personnel, who are involved in planning and calculating the use of low-voltage induction motors.
The course provides the fundamental physical background needed to select the correct motor. It focuses on start-up and line operation for standard applications, such as pumps, fans, compressors and conveyors. The course also covers special features of the motors for inverter operation.
The configuring programs SIZER and DT-Configurator and the technical data in the catalogs are used to calculate a variety of applications.
