Publication number: 20240136913Abstract: A motor drive or bus supply power conversion system includes a rectifier with at least one rectifier switch module for rectifying AC input power. A DC bus is connected to the rectifier and supplies DC output power. An optional inverter is connected to the DC bus and includes at least one inverter switch module for inverting the DC bus voltage to an AC output power. The at least one rectifier switch module and the at least one inverter switch module each include a base plate and a housing connected to the base plate. The housing defines an interior space that contains at least one semiconductor switch. Anti-corrosion features are provided including a conformal coating on printed circuit board assemblies, removable connector covers, dielectric grease coated connections, nano-coated fiber optic transceivers, and an exterior protective film wrap.Type: ApplicationFiled: April 18, 2023Publication date: April 25, 2024Inventors: Garron Morris, Garrett Wolff, Craig Devroy, James Carter, Christopher Genthe

Patent number: 5170863Abstract: A storage and retrieval machine having a base movable in opposite horizontal directions, a mast mounted on the base, and a carriage movable in opposite vertical directions on the mast. A drive is also provided for moving the base and carriage in their respective opposite horizontal directions or opposite vertical directions. A control is connected to the drive for transmitting to the drive for either the base or the carriage, a first signal for a fast acceleration rate in one of the opposite directions of movement, a second signal for a slow acceleration rate in the other of the opposite directions of movement, a third signal for a slow deceleration rate in one of the opposite directions of movement, a fourth signal for a fast deceleration rate in the other of the opposite directions of movement, and a direction signal to move in one of the opposite directions.Type: GrantFiled: July 15, 1991Date of Patent: December 15, 1992Assignee: Harnischfeger EngineersInventor: Craig A. Devroy

Patent number: 5091685Abstract: A shuttle control for a storage and retrieval machine has a supervisory control mounted on the base of the storage and retrieval machine and a shuttle control mounted on the carriage of the storage and retrieval machine. The supervisory control receives shuttle operating commands and information signals and provides operating instruction signals for the shuttle to the shuttle control. The shuttle control receives the operating instruction signals from the supervisory control, produces operating information signals to the supervisory control, and controls the operation of a shuttle motor drive. A circuit having sliding contactors moving with the carriage on vertical slide bars mounted on the mast transmits operating instruction signals and information signals between the supervisory control and the shuttle control at a maximum transmission rate limited by the problems of transmitting the signals through the sliding contactors.Type: GrantFiled: October 19, 1989Date of Patent: February 25, 1992Assignee: Harnischfeger Engineers, Inc.Inventors: B. Chuck Sorensen, Craig A. Devroy

Patent number: 5044859Abstract: A control system for a storage and retrieval machine is disclosed in which a supervisory control is responsive to operating commands from a remote source to provide operating instructions for the control of the base, carriage and shuttle of the storage and retrieval machine. Separate controls for the base, the carriage and the shuttle respectively contain base, carriage and shuttle operating parameters. The base, carriage and shuttle controls are responsive to operating instructions from the supervisory control to respectively control movement of the base, carriage and shuttle in accord with the associated base, carriage and shuttle operating instructions and parameters. A base drive, carriage drive and a shuttle drive are also provided and each include a drive control which produces drive control instructions.Type: GrantFiled: October 19, 1989Date of Patent: September 3, 1991Assignee: Harnischfeger Engineers, Inc.Inventors: B.
