  • Publication number: 20160134224
    Abstract: One embodiment describes a switching device system, which includes a first single pole switching device that selectively connects and disconnects a first phase of electric power to a first winding of a three phase motor; a second single switching device that selectively connects and disconnects a second phase of electric power to a second winding of the three phase motor; in which the first and second single pole switching devices control temperature of the motor by, at a first time, connecting the first phase and the second phase electric power to the motor.

  • Publication number: 20160133414
    Abstract: One embodiment describes a three-phase electromechanical switching device, which includes three single-phase switching devices mechanically and electrically coupled in parallel with one another, each single-phase switching device including a direct current electromagnetic operator that in operation receives a direct current control signal for switching of the device, stationary contacts disposed in a respective device housing, and a movable assembly that in operation is displaced by energizing the operator and that include movable contacts that open and close, with the stationary contacts, a single current carrying path through the respective single-phase switching device; in which each of the single-phase switching devices receives control signals from control circuitry coupled to the operators of the respective single-phase switching devices to cause at least one of the single-phase switching devices to open or close the single current carrying path at a desired time coordinated with a current zero-crossing

  • Publication number: 20160134208
    Abstract: One embodiment describes a method that includes determining a desired torque level of a motor actuated by a motor starter; determining, using a control system, a configuration of the motor starter to achieve the desired torque level, in which determining the configuration includes determining which of a plurality of switching devices in the motor starter should be opened and which should be closed; and instructing, using the control system, the motor starter to implement the determined configuration by opening or closing one or more of the plurality of switching devices.

  • Publication number: 20160103157
    Abstract: The total current flow in a given electric circuit path is estimated by measuring the current in a second parallel current path and applying a ratio of the conductivity of the main and secondary path. Earth leakage current is measured by passing three wires through a toroid so as to detect differential current flow. Each wire is a conduction path wire parallel to each phase cable. The relative harmonic content between the fundamental and higher frequency components of a load current are calculated using a conduction path parallel to the main power cables.

  • Publication number: 20160061872
    Abstract: A testing assembly includes a power supply and at least one circuit phase corresponding to a circuit phase of a motor branch circuit assembly. The circuit phase includes a current detector, a transistor, and an isolating unit. The testing assembly also includes a switch selecting between a RUN mode and a TEST mode. The testing assembly is connected to the motor branch circuit assembly. Prior to placing the motor branch circuit assembly into operation, the testing assembly can provide low voltage testing on the circuit phases of the motor branch circuit assembly. The testing assembly can check for ground faults and line-to-line faults in the motor branch circuit assembly when placed into the Test mode. In this manner, faults destructive to the motor branch circuit assembly can be avoided and corrected.

  • Patent number: 7224557
    Abstract: Control of an induction motor is carried out to limit damaging arcing stress and mechanical stresses placed on the control contactor assembly and the induction motor resulting from the simultaneous or synchronous breaking and making of contactors employed to connect the windings of the motor to a power supply. Asynchronously connecting the windings to the power supply via the asynchronous or non-simultaneous closing of the contactors of a modular contactor assembly reduces the potentially damaging transient current, the associated torque oscillations, and mechanical stresses. The present invention is particularly applicable to delta motors that are started with its windings in a star or wye configuration followed by the reconnection of the windings in a delta configuration when the motor is at normal running speed.

  • Patent number: 6259372
    Abstract: A self-powered wireless transducer is disclosed for monitoring external physical conditions, such as excessive vibrations in a bearing. The transducer includes an energy conversion source, such as a piezoelectric sensor to sense the external physical condition and create a power and characteristic signal that is used to power an RF transmitting circuit. A transmitter is provided to transmit signals indicative of the external physical condition, or changes in that physical condition, such as increased vibrations in a bearing to detect bearing faults before a breakdown. In this manner, the monitored machinery can be shutdown in an orderly manner and preventative maintenance can be completed. The self-powered wireless transducer includes an voltage storage device to receive electrical voltage from the piezoelectric sensor and a voltage detector to detect the level of voltage on the voltage storage device.
