Schulz Electric™ Refurbishes Critical Circulating Water Pump Motor in Only Four Days
Schulz Electric™ was contacted by a nuclear power plant in the New England region that serves a community of over 2 million homes. After five years of service, a 1500 HP, 4 kV, 24-pole circulating water pump motor (measuring approximately 7’ wide, 8’ tall, and weighing several tons) needed refurbishing while the plant was still online. To add to their concern, the power plant is located close to the ocean. The aging motor was not only approaching the end of its serviceable life, but was highly susceptible to moisture intrusion and the salt-laden air, which can build up in air passages within the motor. These environmental conditions can lead to elevated operating temperatures and corrosion developing on the rotor, stator, and shaft components. These factors combined, placed the plant at an increased risk of downtime that could have potentially led to a significant loss of revenue if they were forced into a shutdown event.

In this paper, the electromechanical analysis of a scaled down prototype (1/10 scale in linear dimensions) of the IGNITEX toroidal field (TF) magnet is presented. The primary goal of the IGNITEX Technology Demonstrator (ITD) is to prove the operation of a single turn, 20 T, toroidal field coil powered by a homopolar generator power supply system of 60 MJ, 9 MA, currently operating at the Center for Electromechanics, The University of Texas at Austin (CEM-UT). In order to simulate the actual operating conditions of the full-scale device, the ITD coil will be precooled at liquid nitrogen temperature and driven by the six homopolar generators in parallel. Scaling relationships have shown that electromagnetic loading mechanical and thermal loading of the coil and their relative distribution will approximate well predicted levels of the full-scale IGNITEX device.
