Abstract or Summary
  • The three-phase squirrel-cage induction motor is rugged, compact, inexpensive, can be totally enclosed and requires little maintenance. Its use as a variable speed drive has been limited, however, by the state-of-the art of control components. The advent and continuing development of the silicon controlled rectifier and associated solid-state components has provided the technology for conceiving a static frequency converter to allow continuous motor speed adjustment over a wide range. The static frequency converter system adjusts the motor input frequency and voltage so the motor can match a given load speed-torque requirement. The high cost and low thermal overload capabilities of the solidstate components required for a prototype dictate the use of modeling and simulation techniques for analysis of complex systems such as the static frequency converter motor speed control system.
