摘要： A method and apparatus of determining the position of a rotor at standstill relative to a stator in a synchronous motor elevator machine includes injecting an AC current having a predetermined single frequency and a predetermined initial phase angle into a stator coil of the stator, and sampling the injected current and resultant voltage a predetermined number of times per period of the frequency. Subsequently the method calculates a stator inductance from the sampled voltages and currents using a DFT. By incrementing the initial phase angel a predetermined number of times over a 360 degree cycle, and repeating the injecting, sampling, and calculating with each incremented phase angle, the algorithm provides a predetermined number of calculated stator inductances. The position of the d axis relative to the stator is then determined from the minimum of the calculated stator inductances.

摘要： A control system having a host computer and one or more control computers connected to an interface for control of a process or machinery. The control computers are capable of automatically initiated network address assignment and configuration when powered up after installation. The network address is based on a location identifier situated in the interface that corresponds to a specific connection thereof to the control computer. The control computer reads the location identifier from the interface and requests a network address. The host computer assigns the network address based on the location identifier. Configuration of the control computer then proceeds. The procedure applies to newly installed control computers, whether first time installment or a replacement for a failed control computer.

摘要： A method and system is provided for constructing a multilevel structure using a hybrid top chord bearing floor framing system. The method and system may include a top chord bearing floor truss positioned on a first frame structure. The top chord of the truss may include a load-bearing interface with a top surface and a bottom surface. The truss may be wholly supported by the load-bearing interface of the top chord. The method and system may further include a second frame structure on the top surface of the truss. The first frame structure may be secured to the second frame structure via a fastener that extends through both the second bottom load bearing member and load-bearing interface of the truss into the first top load bearing member of the first frame structure.

摘要： Methods and apparatus for converting power from a power source are described. In one example embodiment, the method includes controlling multiple transformer and switchgear units coupled to a power source, and controlling multiple converter units connected in parallel. Each converter unit is coupled to a respective one of the transformer and switchgear units to form an individual thread. The transformer and switchgear unit and power converters are controlled so that the carrier waveforms for each individual thread are interleaved between each other over a carrier cycle.
