Abstract:
A possibility for extending the speed control range of conventional induction motors under pulse control is treated. This is obtained by connecting capacitors in series to each phase of the motor. As a results, the short circuit reactance will he decreased, the critical slip will be increased and the control range will be extended. Both the starting and maximum torques as well as the power factor will be increased. Expressions to determine the necessary capacitance of condensers, the slip and the torque curve are given.
