Maintenance & Troubleshooting of Electric Motor

With the industrial growth, it has become necessary to monitor the condition of the machine/system. Electrical machines mainly power transformer and electric motors being the most sensitive part has great importance for the facilities to run the production without any abnormalities. A wide variety of tests have been developed and standardized to help manufacturers and users of motor to assess the condition. This training course will provide an understanding of electric motor, their materials, components and how they operate. It also emphasizes the importance of motor management life especially for those electric motors which have been in operation for 10 years and more. The course will address in detail all aspects related to electric motor principles, calculations, operation, testing and maintenance.

Objectives

This course aims are to provide understanding of the fundamentals and constructional features of electric motors with particular reference to the design, testing, operation and maintenance. Participates will gain a detailed appreciation of the following:

Practical solution for specifying, operating, and maintaining electric motors in a utility or in a plant environment.
Comprehensive understanding of principles, protection, maintenance and troubleshooting of electric motor.
