ELECTRIC MOTOR ROTOR

Last crawled date: 1 year, 11 months ago

This job was done from Mr. Sweo's 2D sketches. It was modeled and rendered in IRONCAD.

This model is of the interconnection conductors in the rotor of a brush-less doubly-fed induction machine, the subject of Mr. Sweo's patent # 6,278,211. These conductors reverse the direction of rotation of the AC current in the two rotor lamination stacks, which are shown as the discs on opposite ends of the assembly with 28 slots for conductors. The conductors which extend through the lamination stacks are connected by end rings at the outside ends of the dual rotor stack.

The use of the brush-less doubly-fed machine is as a variable speed motor or generator, where this method of construction allows control of all the power output over a limited speed range with a control rated for only a portion of the total power output. The total motor plus control cost is estimated to be 20-30% below that for a standard inverter controlled motor in the 100 HP up size range.
