Title: Speed control unit for induction motor
Inventor: YANAGISAWA TADAHIRO
IPC: H02P1/26
Filed: 1986-05-16
Abstract: PURPOSE:To impress the excess current in starting, by V/F controlling a motor in deciding the slip frequency command value with a difference between the primary current detection value and the primary current command value. CONSTITUTION:A slip angle frequency command generation circuit 7 operates a slip angle frequency command value omegaSR from the current command value IIR and the current detecting element output II. A low value selecting element 8 inputs the speed command values omegaIR and omegar+omegaSR, the smaller value of both of which is outputted as an angle frequency command value to a three-phase voltage command value generation element 2. In starting, when omegaIR goes up at the specified speed, the primary angle frequency omegaI goes up along with the rise of omegaIR in the range of omegaIR<omegaSR. When it becomes omegaIR>omegaSR, omegaI=omegaSR and omegaI stops increasing. As a result, the outflow of excess current can be prevented.
