Case Study 5500HP, 13,200v, Synchronous Motor: (Part 5) Electrical Design of Rotor
July 23, 2019
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
