This course is designed to provide participants with the skills to understand how electric motors and their associated motor protection and control systems are applied in industrial process plants in both non-hazardous and hazardous environments (oil & gas, mining and minerals processing and heavy industries). The electric motors and motor protection program is interactive and encourages delegates to participate through questions and answers, along with opportunities to discuss with the presenter specific issues which may result in appropriate solutions.
By the end of this course delegates will be able to:
- Undertake a detailed review the different types of electric motors available
- Learn the different starting and control methods used
- Understand the requirements for electric motors in hazardous areas
- Learn the importance of selecting correct bearings and lubrication systems
- Understand the types of motor protection required for different motor types
- Understand the terms Intelligent Motor Control and Motor Manager
- How they are used to control and automate many motor control functions
- Learn about comprehensive electric motor maintenance programs
- Evaluate whether a motor can be repairs or requires replacement
