These differences necessitate a different testing standard to ensure consistency,
29、 repeatability and dependability of the test results. For clarification, the significant differences are listed below: a) The LIM has a power factor and an electric efficiency substantially lower than those of rotary motors, because its magnetic gap length is several times that of the rotary motors.
30、 As such, the assumption made for the rotary induction motor that the primary leakage reactance is significantly less than the mutual reactance is no longer valid. b) The traction efficiency of a LIM does not include the mechanical transmission, typical of rotary motor propulsion. c) LIMs produce di
31、rect thrust between the primary and secondary without the need for mechanical contact. Therefore, there are no adhesion limits due to the rail and wheels contact of the typical rotary drive. No spin/slide controls are needed with LIMs and thus there is no need for testing of this function. d) LIMs p
32、roduce not only thrust (which is in the longitudinal direction) but also normal and lateral forces which are effectively eliminated in the rotary induction motor, due to the symmetrical geometry of rotary motor. The normal force is either an attraction or a repulsion between the primary and secondar
33、y. The effect of these forces should be considered on deflection of primary and secondary and for their mechanical strength and rigidity, particularly as the deflection will affect the gap between primary and secondary and thereby change the LIM performance. e) The normal force mentioned in d) has a
34、 direct effect on the design of magnetically levitated vehicles. Depending on whether the normal force is attractive or repulsive, this force will either assist the suspension of the vehicle or oppose it. Thus testing of the LIM must ensure that the force occurs in the appropriate part of the LIM op
35、erating range. f) Information in Table 1 should be shared with subsystem component designers. Particular attention is drawn to the need for collaboration between the designers of the LIM and its associated converter as detailed in 5.1.

36、RACTION SHORT-PRIMARY TYPE LINEAR INDUCTION MOTORS (LIM) FED BY POWER CONVERTERS 1 Scope This International standard applies to short-primary type linear induction motors (LIM) for propelling rail and road vehicles. This standard applies to a specific configuration of LIM that has the primary mounte
37、d on either the vehicle body or trucks and a secondary that is fixed to the track and that is connected only by a magnetic field with the primary. The object of this standard is to allow the performance of a LIM to be confirmed by tests and to provide a basis for assessment of its suitability for a
38、specified duty. The rating of LIMs fed in parallel by a common converter should take into account the effect on load-sharing due to differences of gap length and of LIM characteristics. The user should be informed of the maximum permissible difference in gap length for the particular application. Th
39、e electrical input to LIMs covered by this standard should come from an electronic converter. NOTE At the time of drafting, only the following combination of LIMs and converters had been used for traction applications, but it may also apply to other combinations which may be used in the future: LIMs
