摘要： A system for monitoring a useful life of an insulation component of a braking resistor includes a sensor that can be embedded below an outer surface of the insulation component to measure a temperature of the insulation component; and a controller connected to receive a signal from the sensor indicative of the measured temperature of the insulation component, and programmed to compare the measured temperature of the insulation component to a predetermined threshold activation temperature for the insulation component, decrement from a predetermined useful life value for the insulation component a life depreciation value assigned to the measured temperature to determine a remaining life value of the insulation component if the measured temperature of the insulation component is greater than the threshold activation temperature, compare the remaining life value to an end-of-life value for the insulation component, and generate a warning signal if the remaining life value is at or below the end-of-life value.

摘要： A braking grid cooling system may include a fan having a hub supporting a rotor and at least partially enclosing a stator, and a plurality of fan blades connected to and projecting radially from the hub; and a dynamic braking grid receiving the fan in a nested relation such that a combined height of the grid and the fan is less than a sum of a height of the grid and a height of the fan.

摘要： A method of controlling operation of a multi-phase induction motor may include transmitting a low-speed operation signal by a master computer to a control signal board for low-speed operation of the motor; the control signal board receiving the low-speed operation signal, and in response to the low-speed operation signal, the control signal board sensing that the master computer is not simultaneously transmitting a high-speed operation signal, and in response to receiving the low-speed operation signal and not simultaneously receiving the high-speed operation signal, closing contactors in a power section to transmit power to the motor for low-speed operation, whereby the motor is connected to a source of multi-phase power and operates at low-speed; and the control signal board transmitting a first feedback signal to the master computer that the motor is connected to the source of multi-phase power and is running at low speed.

摘要： Apparatus including a monolithic, motor/generator phase insulation article having a manufactured state and a ready-to-use state. The insulation article has longitudinally-spaced-apart first and second tabs and flexible, transversely-spaced-apart first and second legs each having a first end monolithically joined to the first tab and a second end monolithically joined to the second tab. The first and second tabs are disposed longitudinally closer together in the manufactured state than in the ready-to-use state. In the manufactured state the first and second legs each have a more serpentine shape, and in the ready-to-use state the first and second legs each have a less serpentine shape. A method for manufacturing the insulation article is also described which cuts a monolithic, substantially-rectangular sheet of motor/generator phase insulation to create the insulation article.

摘要： An AC-induction-motor rotor lamination has a longitudinal axis and circumferentially spaced apart and closed rotor slots. Each rotor slot includes first through fifth corners, a straight slot base, straight first and second slot sides, and first and second curved sides. The slot base extends from the first corner to the second corner, the first slot side extends substantially radially inward from the second corner to the third corner, and the second slot side extends substantially radially inward from the first corner to the fourth corner. The first and second curved sides extend from a corresponding one of the third and fourth corners to the fifth corner. A rotor lamination having slot sides extending substantially radially outwardly from the second and first corners, and rotor laminations having open rotor slots (with slot sides extending substantially radially inward or outward) are also described.

The outer ring is substantially coaxially aligned with the central longitudinal axis and is attached to the base plate proximate the circumference. The base plate has a substantially-planar first surface having a central recess substantially coaxially aligned with the central longitudinal axis and having circumferentially-separated, first and second peripheral recesses each radially spaced apart from the central recess and extending radially inward from proximate the circumference. The outer ring longitudinally extends beyond the first surface. The tankhead assembly is devoid of any gussets attached to the base plate and is devoid of any gussets attached to the outer ring.
