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.

An intense current in a hypothetical superconducting ring wire creates circular symmetric magnetic field. The calculation of such a field is performed numerically. Complete elliptic integrals of the first and second kind with modulus “k” approaching unity in the vicinity of the current carrying wire are used. The trajectories of charged particles moving along the current carrying wire are calculated neglecting space charge effect. With proper parameter selection toroidal magnetic field confines charged particles. Cycloid type trajectories without touching the axial current carrying wire are obtained. Such an arrangement could be used as charged particle beam guiding or storage system.
