Patent number: 11916444Abstract: Disclosed is a hermetic AC electric motor that includes harmonics shunting such that high frequency harmonics are shunted from the AC electric motor without the use of one or more high frequency filters in the associated motor drive. A related method of operating an AC electric motor includes shunting high frequency harmonics to a fluid passing through the AC electric motor. Also disclosed is a simplified variable speed motor drive system which eliminates the need for a filter for removing high frequency harmonics.Type: GrantFiled: May 14, 2021Date of Patent: February 27, 2024Assignee: Trane International Inc.Inventors: Richard M. Heiden, Jay H. Johnson, Joseph M. Heger, Charles J. Peterson

Patent number: 6705100Abstract: A purging device for a system accumulating condensable and non-condensable gases. The purging device comprises: a purge tank; apparatus receiving the condensable and non-condensable gases from the system and directing said gases into the purge tank; apparatus condensing the non-condensable gases into a condensed form; apparatus accumulating the non-condensable gases in a header space; apparatus returning the condensed gases from the purge tank to the system; apparatus controllably removing the accumulated non-condensable gases from the header space; and apparatus generating controlled flow in the condensable and non-condensable gases.Type: GrantFiled: May 15, 2003Date of Patent: March 16, 2004Assignee: American Standard International Inc.Inventors: Richard M. Heiden, Robert J. Roth, Brian T. Sullivan, Steven E. Wolfgram

Patent number: 6679076Abstract: A centrifugal chiller includes both a unit-mounted full-voltage starter and a unit-mounted reduced-voltage starter. The chiller is rather large with a rated cooling capacity of at least 300 tons and is driven by a motor that is powered by at least 2,000 volts. The chiller includes an evaporator shell and a condenser shell in a staggered arrangement to provide a combined height of between 6 and 12 feet and a combined width of between 5 and 8.5 feet. The staggered arrangement of the shells plus mounting the two starters at opposite sides of the motor provide a chiller whose outer dimensions permit the chiller to be shipped as a single package without exceeding certain shipping limits.Type: GrantFiled: April 17, 2003Date of Patent: January 20, 2004Assignee: American Standard International Inc.Inventors: Joel S. Duga, John A. Komperud, Richard M. Heiden

Patent number: 5521566Abstract: A solenoid unit for use in high amperage environments includes a hollow cup-shaped housing having a closed end and an open end. A contact section is located adjacent to the closed end, and a coil section is located adjacent to the open end. The closed end includes an end wall. First and second power contact terminals each include a threaded member extending exteriorly for receiving a lead clamping nut. Each terminal includes an enlarged mounting head embedded within the end wall, with an inner contact extending from the end wall. Each head includes a circumferential knurled surface to oppose rotational and axial forces and thereby permits high clamping torque forces on the nut. A bridging contact is aligned with the inner contact ends of the terminals and moves axially thereof. The housing includes inwardly extending opposed locating members which define the contact chamber and guide the bridging contact within a free space to cool the contact assembly.Type: GrantFiled: August 25, 1994Date of Patent: May 28, 1996Assignee: Clum Manufacturing Company, Inc.Inventors: Larry J. Krubsack, Richard M. Heiden, Allen L. Handy
