Patent CA-2180805-A1 (CA)
Title: System for Equalizing the Load of a Plurality of Motors
Inventor: LAPOTA ROBERT J
IPC: H02P5/52
Filed: 1996-07-09
Abstract: A system having two or more A.C. motors driving the same load. The stator windings and rotors of both motors each conduct current having a vector representative of a magnitude and angular position of the current in the respective rotor and stator winding. Stator current sensors are provided for producing an indication of the magnitude of the stator current vector to each motor. Encoders are provided for sensing the rotating speed of each of the rotors from which can be calculated the angular position of the rotor load current vector with respect to the rotating stator flux current vector. A first torque control controls the magnitude of the stator current of a first one of the motors such that the stator flux current vector of the first motor and the rotor load current vector of the first motor are angularly separated by 90°. This angular relationship produces maximum torque at the rotating speed of the first motor. A second torque control receives an indication of the magnitude of the torque of the first motor from the first torque control. Using this information, the second torque control controls the magnitude of the current of the stator of the second motor such that the angular position of the stator flux current and rotor load current vector of the second motor have a 90° separation so that the second motor produces substantially the same magnitude of torque as the first motor.

Abstract: An inflatable bag body comprises a multilayered film. The multilayered film includes: a base film layer having first and second surfaces; a coating layer formed out of an anchor coating material on the first surface of the base film layer; a first polyolefin resin layer formed out of a polyolefin resin material on the coating layer; a deposited metal layer deposited a metal on the second surface of the base film layer; and a second polyolefin resin layer formed out of a polyolefin resin material on the deposited metal layer. The multilayered film is externally exposed with the second polyolefin resin layer to cover the base film layer and the deposited metal layer. The multilayered film has peripheral portions connected with each other by heating and pressing the first polyolefin resin layer along the peripheral portions. The deposited metal layer cannot elastically expanded while the base film layer and therefore apt to be damaged to have fine cracks. The damaged deposited metal layer can be protected by the second polyolefin resin layer from drops of water and aqueous vapor to prevent the damaged deposited metal layer from being oxidized and from partly peeling from the base film layer while being exposed to the weather. And The second polyolefin resin layer has non-electrical conductivity thereby making the inflatable bag body restrain electrical conductivity.
