Abstract

ABSTRACT ABSTRACTThis paper re This paper re This paper re This paper reports the enhancement of the ou ports the enhancement of the ou ports the enhancement of the ou ports the enhancement of the ou the asynchronous mode by direct capacitance injection into the auxiliary winding of the machine, which is the asynchronous mode by direct capacitance injection into the auxiliary winding of the machine, which is the asynchronous mode by direct capacitance injection into the auxiliary winding of the machine, which is the asynchronous mode by direct capacitance injection into the auxiliary winding of the machine, which is electrically isolated from the main winding but magnetically coupled to it. It is shown electrically isolated from the main winding but magnetically coupled to it. It is shown electrically isolated from the main winding but magnetically coupled to it. It is shown electrically isolated from the main winding but magnetically coupled to it. It is shown injected capacit injected capacit injected capacit injected capacitance, the ance, the ance, the ance, the torque and output power of the machine is markedly enhanced at improved power factor. torque and output power of the machine is markedly enhanced at improved power factor. torque and output power of the machine is markedly enhanced at improved power factor. torque and output power of the machine is markedly enhanced at improved power factor. With the enhanced output power achievable by capacitance injection, the transfer field machine can compare With the enhanced output power achievable by capacitance injection, the transfer field machine can compare With the enhanced output power achievable by capacitance injection, the transfer field machine can compare With the enhanced output power achievable by capacitance injection, the transfer field machine can compare favorably favorably favorably favorably with an equivalent induction motor except t with an equivalent induction motor except t with an equivalent induction motor except t with an equivalent induction motor except t frequency of the stator mmf wave (ω frequency of the stator mmf wave (ω frequency of the stator mmf wave (ω frequency of the stator mmf wave (ωr r r r = = = =
