System and method for fast discharge of a ring motor field
High-power synchronous motors are commonly used in mining operations, for example, in gearless draglines, gearless conveyor drives, and gearless mill drives. Substantial electromagnetic energy is stored in the inductive field windings. In the event of a system fault, such as a short in the direct current power source exciting the field windings, the electromagnetic energy needs to be discharged from the field windings. This electromagnetic energy is typically dissipated as waste heat through a resistor. Disclosed is a field discharge system in which the electromagnetic energy is captured and stored as electrical energy in a capacitor. If an ultracapacitor bank is used for storage, the charged ultracapacitor bank can be used as a backup or auxiliary power source for mining operations. The discharge time is sufficiently small that high speed circuit breakers are not needed to disconnect stator windings from the alternating current power source when a fault occurs.

Excavator drive system with bi state motor transfer switches
An excavator drive system wherein one of a pair of propulsion motors shares one of a pair of inverter power sources with another of a pair of motors dedicated to crowd and hoist motions. A pair of non-volatile bi-state switches, triggered under control of a controller, allow sharing of inverters between hoist and propel 1 motors. Another pair of switches allows inverter sharing between propel 2 and crowd motors. Each pair of switches enables change over and power transfer from one of the paired motors to the other motor. The bi-state switches enable quicker transfer of power between motors than transfer switches employing external motor-powered mechanical transfer linkages. Bi-state transfer switches also maintain transfer coupling status in the event of power failure to the switch actuators, allowing an excavator operator to continue the drive function in operation prior to the switch power failure.

Method for measuring slow roll characteristics of partially machined shaft of an electrodynamic machine
An electrodynamic machine shaft slow roll measurement testing and remediation method that can be performed on a partially machined shaft. Upon completion of slow roll tests on a partially machined shaft the manufacturer may complete machining of shafts that successfully meet the test specification. If a partially machined shaft fails the test specification, the manufacturer at its option may attempt to remediate the shaft, so that it successfully meets slow roll specification upon re-testing. Exemplary remediation steps may include further concentricity machining to reduce mechanical runout or shaft treatment, such as by heating and/or quenching to reduce electrical runout. Partially machined shafts that fail slow roll test specifications (with or without remediation efforts) may be scrapped or otherwise recycled without, completing final machining operations.

System and method for providing auxiliary power by regeneration power management in mobile mining equipment
A method for operating an ultracapacitor system used in a mining excavator powered by an electrical power source. The method includes the step of detecting whether a line power from the electrical power source is present. Next, a voltage level of the ultracapacitor system is measured if the line power is not present. The measured voltage level is then compared with a minimum voltage level for the ultracapacitor system. If the measured voltage level is more than the minimum voltage level, auxiliary power is supplied from the ultracapacitor system to operate mining excavator systems. The auxiliary power may be used to power electronic systems and components such as computers, displays, control systems, gas insulated switchgear and lighting systems.

Method of tuning bending and torsion stiffness of ducted rotor core of an induction motor
Electrodymamic machine rotating mass, including for example induction motor rotors, stiffness tuning methods include selective orientation and compression of modular tie rod assemblies into through bores formed in the rotor lamination core outboard of the rotor shaft during motor manufacture, repair or refurbishment. Stiffness tuning enables a motor manufacturer to tune a rotor's rotordynamic stability, and hence the assembled motor's critical vibration speed. Electrodynamic machine rotating mass tuning can be adjusted in response to machine physical design, operational application and manufacturing variation attributes that impact the assembled machine's critical vibration frequency. Thus the present invention offers a systematic, holistic approach to motor vibration refinement through use of a simple kit of modular tie rod assemblies oriented and tightened in a selected array. Rotor stiffness tuning can be tested virtually on computer work stations. Additional actual rotor stiffness tuning can be performed during manufacture.
A lubrication system for an electrodynamic machine including therein an internal oil sump and at least one oil ring hydrodynamic bearing, wherein the oil ring is in fluid communication with oil, in the sump and replenishes oil in the bearing. The lubrication system includes an electrically powered oil sump pump that is oriented within the sump. An of intake is coupled to the pump and is in fluid communication with oil in the internal sump. An oil discharge line is coupled to the pump discharge. The distal end of the discharge line is oriented proximal the motor bearing, so that oil discharged therefrom replenishes oil in the bearing and shaft journal interface. The lubrication system oil discharge parameters are independent, of the motor speed, load or physical orientation, and may be varied by a controller coupled to the oil sump pump.
A dynamoelectric machine, such as a totally enclosed fan cooled (TEFC) induction motor has a double-wall bearing housing heat shield that envelops and thermally isolates the bearing housing from the rest of the motor housing interior. The shield defines an air channel between the shield outer and inner walls. Optionally the air channel may be constructed to enable circulating air flow through a shield intake in communication with an air flow source, such as air ducted from the TEFC motor axial cooling fan. The air channel also defines an exhaust. Air flow within the air channel transfers heat out of the motor housing, lowering bearing housing operating temperature. Air flow rate may be varied in response to motor operational parameters.
