| Abstract |
When the construction of LIM gives no possibility to reach the required speed if is determined slip of LIM, the LIM must be supplied by voltage with changeable frequency from frequency converter. The paper deals with the properties of low speed LIM. It is proved that LIM current dependence upon slip is negligible. The expressions of characteristics of frequency controlled drives with linear induction motors were derived and analyzed. It is proved the law of changing LIM supply voltage when the frequency is changed and the LIM phase current changes with slip and is constant (does not depend upon slip). It is analyzed control of LIM by changing of voltage also there are presented the results of modeling of low speed LIM operating in start-stop mode. |
