Patent JP-H03203580-A (JP)
Title: Inverter-driven compressor
Inventor: UCHIBORI MASAHARU
IPC: H02P1/26
Filed: 1989-12-27
Abstract: PURPOSE:To lower the withstand voltage of parts by connecting the stator windings of a motor element into delta form, rectifying the AC power, with 100V single-phase output, of the motor element by voltage doubler rectification, and specifying the diameter of the stator windings to obtain approximately the same output as a motor having Y-connected stator windings. CONSTITUTION:The stator windings 9, 10, and 11 of a three-phase induction motor for driving a compression element are connected to the input terminals U, V, and W of a compressor into delta form. To obtain by voltage doubler rectification the same output as in the case of Y-connection, the quantity of currents passing through the stator windings have to be increased. To increase the currents, only the resistances must be decreased by increasing the cross sectional areas of the windings. When the output of the motor is constant AT (current multiplied by the number of windings) is constant, therefore, the cross- sectional area of the stator windings is in inverse proportion to the applied voltage. Hence stator windings of 1.16 times or more as large in diameter are sufficient for the delta connection and the distances between the teeth of a stator do not need changing.
