Small induction motors supplied from high-frequency transistor invertors
Abstract
The design and development of an electric drive with an operating speed of 5.000 - 11,000 rev/min are described. To obtain these high speeds an induction motor is supplied from a transistor inverter. Due to the high operating speed, the power/weight ratio of the motor is high. A high proportion of the cost is associated with the inverter. For this reason single-phase systems, rather than 3-phase systems, are considered. The inverter output waveforms employed are simple to generate, but are nevertheless adequate for supplying small induction motors. Special problems in using transistors for this application are discussed and resolved. operation and construction of a 3-phase transistor alternator are also described.
