摘要： 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.

摘要： 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.

摘要： 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.
