Electrical Motor Maintenance & Troubleshooting
- Electrical motors represent industry's workhorse in small, medium and large size applications. It is no exaggeration to suggest that more than 50% of the energy consumed worldwide is converted by AC motors into work and these motors are controlled by drives.
- Understanding maintenance and troubleshooting procedures of such vital industrial equipment means that reduced downtime and increased productivity are the immediate benefits for the company and its management.
Learning Outcomes
- Understand the operation and construction of AC electrical motors and the electrical drives based on modern electronics technology.
- Become more confident on how to maintain both motors and drives following well-established industrial procedures as outlined in standards.
- Become familiar with troubleshooting methods for both motors and drives following methodologies that have been developed by manufacturers in order to reduce downturn time dramatically.
- Learn how to utilize single-line drawings, and other documentation to successfully perform commissioning, maintenance and troubleshooting of both motors and drives.
- Become exposed to industrial standards and case studies so that to be able to apply this knowledge in the industrial plant as quickly and efficiently as possible.
