Description

20-D LM Solve; 1 each. Statement of Work: The model should be configured to analyze linear induction motor geometries with multi-phase coils on the stator excited to produce a traveling field. May be single or double sided. The accelerated "plate" sits close to the slot openings for a single sided motor or in the gap of a double sided motor. The motion should be along the X-axis. The model should allow a uniform spacing of the coils/slots. The accelerating plate is coped with by changing the frequency of the supply rather than by enlarging the spacing of the coils. The plate is made of a conducting, non-magnetic material, and is of finite length compared to the stator (for example: a plate of 1 to 7 meters on a stator of 10 to 100 meters). It is important to capture the dynamic end effects of the plate in the solution. The model should allow a mechanical load on the plate from any forces that may oppose the motion, including friction, wind resistance, external loads, etc. This load should be able to be a function of the speed. The model should allow external circuits (R.L.C) to be connected to individual coils. Also, the model should allow switches and voltages to be connected to individual coils to allow controlled ;turn-on and excitation of the coils. The model should allow both sinusoidal voltages with variable frequency and user defined waveforms (up to 100 points).The model shoulbe be able to conduct non-linear analysis. This is a sole source requirement to Vector Fields, Incorporated of Aurora, IL. The following additional information is required: business size, delivery date after receipt of order, payment terms, cage code, delivery: destination or origin, tax id number, duns number, and are you CCR registered. Closing date is 19-SEP-2000.
