Patent number: 12117363Abstract: When a gateway, which provides one or more drivetrain domain specific knowledge services and include one or more simulation tools, receives a request relating to a drivetrain, the request containing identification information identifying one or more components of the drivetrain, and possibly one or more operation conditions, the gateway retrieves, based on the identification information, component information on one or more components of the drivetrain, the component information indicating for each component a component type. The gateway also retrieves, based on one or more component types in the component information and received one or more operation conditions, if any received, one or more values. Then the gateway uses at least the retrieved one or more values as input for a simulation; and outputs a simulation result for the drivetrain and/or for one or more of components the drivetrain.Type: GrantFiled: October 30, 2020Date of Patent: October 15, 2024Assignee: ABB Schweiz AGInventors: Tommi Ryyppö, Jari Jäppinen, Jan Westerlund

Patent number: 11888366Abstract: The disclosure relates to an electric induction machine in which a chamfer region is provided between each respective rotor groove and rotor bar at a position corresponding to a radially outer internal corner region of the rotor groove. Suitably, the chamfer region has a relative magnetic permeability less than that of the rotor frame, and an electrical resistivity higher than that of the rotor bar. Moreover, a minimum diameter of the chamfer region is suitably larger than a manufacturing-tolerances derived maximum clearance between the respective rotor groove and robot bar, if any.Type: GrantFiled: December 28, 2020Date of Patent: January 30, 2024Assignee: ABB Schweiz AGInventors: Mikael Heikel, Mark Szucs-Bartfai, Aron Szucs, Blanka Szucs-Bartfai, Zsolt Kovacs, Jan Westerlund

Publication number: 20210301472Abstract: The thermal conductivity of the electrical paper insulation could be increased if the paper material is either enriched or fully substituted by a material with higher thermal conductivity. Diamond as enrichment material will be the right choice because besides the high thermal conductivity, it also acts as an excellent electrical insulator and has good mechanical properties. The thermal conductivity of the diamond is kdiamond=2200 [W/mK], that is even more than 7000 times higher than the paper material. Diamond enriched insulation papers have not existed before this invention. In the proposed structure the diamond particles are held in place also by the fibrous substance of the paper itself, without the need of a holding matrix material by default, as shown in FIG. 1. The diamond particles mixed in the paper can also penetrate the paper across creating a thermal bridge between the insulated parts while maintaining strong electrical insulation.Type: ApplicationFiled: July 24, 2019Publication date: September 30, 2021Inventors: Zlatko KOLONDJOVSKI, Aron Szucs, Jan Westerlund

Patent number: 10097123Abstract: A synchronous machine and related systems include a stator and rotor separated by an air gap. The rotor includes a rotating DC power supply coupled to exciter windings disposed adjacent the air gap. Power from air gap harmonics, including air gap slot harmonics induce current in the exciter windings, which is rectified and supplied to the rotor field windings. In operation, a desired current level in the rotor field windings can be achieved through control of the DC power supply or superposition of harmonics into the stator winding current which induces the prescribed current in exciter windings.Type: GrantFiled: October 6, 2017Date of Patent: October 9, 2018Assignee: ABB Schweiz AGInventors: Ghanshyam Shrestha, Darren Tremeling, Waqas Arshad, Wen Ouyang, Jan Westerlund

Patent number: 5658610Abstract: A method and device for high-pressure treatment of liquid substances, for example foodstuffs. The substance undergoes a cyclic process whereby a limited amount of the substance during each cycle is pressurized in a pressure intensifier (1) to a predetermined pressure and is then maintained at this pressure for a predetermined period of time. After the substance has been pressurized in the pressure intensifier (1), it is conducted to a pressure chamber (10) while maintaining the predetermined pressure. The substance is further caused to reside in the pressure chamber (10) for the predetermined period of time by being caused to pass over a predetermined distance between an inlet (9a) and an outlet (9b), which are arranged in the pressure chamber (10).Type: GrantFiled: September 22, 1995Date of Patent: August 19, 1997Assignee: ASEA Brown Boveri ABInventors: Carl Bergman, Jan Westerlund
