Case Study 5500HP, 13,200v, Synchronous Motor: (Part 5) Electrical Design of Rotor - HECO

In part 5 of this case study, Todd Hatfield will be reviewing the electrical design of the rotor. Below is a short 3 minute video showing the steps involved in creating the new coils for this 5500HP, 13,200v, Synchronous Motor’s Rotor.

The video below will discuss:

• The decision to keep the coil design and duplicate it or to come up with a new and improved design
• Temperature differential of about 10º C – the insulation life “doubles” for every 10º C decrease in temperature
• The CAD drawing of field coils that were mounted on the spider
• Rewinding the new rotor coils and mounting the poles with the new coils

Before starting the video, make sure you are all caught up with the series starting with…

• What is an AC Synchronous Motor?
• Part 1 – Problem Identification and Potential Solution
• Part 2 – Evaluating Surplus Motor Option and Initial On-site Application
• Part 3 – Electrical and Mechanical Redesign Engineering
• Part 4 – Mechanical Design of Shaft and Rotor
