摘要： 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.

摘要： The present invention provides an electrical isolation apparatus having independently controllable contactors. The isolation apparatus includes a contactor for each phase or pole of an electrical device as well as each phase or pole of a load. Each contactor is constructed so that each includes multiple contact assemblies that may be independently controlled to open and close. Moreover, the contactors within a single contactor assembly or housing can be independently controlled so that the contacts of one contactor can be opened without opening the contacts of the other contactors in the contactor assembly. Additionally, the contactors are constructed and controlled such that a single line side contactor and a single load contactor open simultaneously when an open circuit condition is desired.

The apparatus includes a contactor assembly having multiple contactors such that each contactor is separately controlled such that one contactor may be closed without the other contactors of the assembly being closed. The contactors are arranged such that a pair of contactors is caused to close following a zero-voltage crossing of a power signal. A third contactor is caused to close after the pair of contactors has closed.

摘要： A method an apparatus is disclosed for preventing contact welding during fault conditions. This fault current tolerable contactor includes two magnetic components, one in operable association with the movable contacts, and the other fixable attached above the movable contacts such that when a fault condition occurs, a high magnetic force is created to draw the two magnetic components together thereby opening the contacts. The magnetic force keeps the contacts open at least until current zero, and preferably a defined time thereafter to provide enough time for the contacts to cool and prevent welding upon the closure of the contacts.

摘要： An electromagnetic operator includes first and second coils wound coaxially. An armature partially surrounds the coils for channeling flux during energization of the coils. The armature may be formed of a bent plate and secured to a ferromagnetic support. A control circuit applies energizing signals to the coils during operation. Both coils are energized during an initial phase of operation. One of the coils is subsequently released or de-energized automatically. A timing circuit removes current from the second coil after a variable time period. The time period may be a function of the configuration of the timing circuit, such as an RC time constant, and of the energizing signal.

摘要： A solid state motor starter, commonly referred to as a soft starter, is constructed in a manner to be easily manufacturable while at the same time combining all the required components in a relatively small package. A solid state power switch is clamped between a pair of bus bars in an offset manner to accommodate a discrete switching relay mounted in an inverted manner between the line input and the bus bar in communication with the load outputs. When in a motor run mode, current is shunted away from the solid state power switching device and through the switching relay, a substantially linear current path is achieved to reduce power loss and heat buildup. The arrangement allows for a heat sink mounted to one of the bus bars with adequate spacing between the heat sink and the discrete relay for insertion of a cooling fan. Current sensing is achieved with a Hall effect sensor mounted to the bus bar in a small current sensing region that is created by having a pair of slots in the bus bar to direct current. A pair of magnetic pins extend perpendicular from the bus bar to create the magnetic flux for the Hall effect sensor to sense current flow through the current sensing region. The Hall effect sensor circuit board also contains a thermistor which is mounted with adequate insulation yet in thermal communication with the bus bar.

摘要： A motor overload coil control is disclosed for use in a motor starter/relay contactor. The control includes an 8-bit, 8-pin microcontroller that together with an I/O reduction circuit, is capable of functioning 13 I/O's with only 5 I/O pins on the microcontroller. Three remote signals are prioritized and reduced on one input line to the microcontroller. The control includes three-phase current measurement from three Hall effect current sensors positioned one on each leg. The system includes current integration to provide a single current input to the microcontroller. A full load amperage (FLA) adjustment allows use on a wide range of motors. The microcontroller uses the FLA adjustment and the current signal to find an appropriate I2t value for real-time monitoring of the operating temperature of the motor. A status indicator is provided having an LED output to show the status of the system and indicate the motor temperature, when appropriate. After the coil is initially pulled in, the microcontroller generates a PWM signal to keep the appropriate coil pulled in with reduced power. The system includes an internal 24 VDC sensor to ensure proper DC voltage level, and to adjust the PWM for variances in voltage levels. Pushbutton test and reset switches are provided, as well as a solid state remote reset.

摘要： A fixture is provided for facilitating the fabrication of a motor controller of the type including a power substrate module and a control circuit board mounted to and electrically coupled to the power substrate module via a plurality of conductors. The fixture is preferably a ring-like structure made of epoxy-fiberglass laminate. Apertures for engaging and holding the conductors are provided in the fixture at locations corresponding to conducting pads on the power substrate module. For fabrication, the power substrate module and the fixture are preformed and solder is disposed on the conducting pads of the module. During fabrication, the conductors are inserted into the apertures in the fixture and the fixture and conductors are positioned over the preformed power substrate module to bring the conductors into contact with the conducting pads. The fixture and power substrate module are then passed through a reflow oven to melt the solder and complete the connection of the conductors to the module. The fixture is left in place and connections to the conductors, such as by installing a control circuit board, may be completed in subsequent process or assembly steps.
