Editing Linear induction motor (section)

==Performance==
Linear induction motors are often less efficient than conventional rotary induction motors; the end effects and the relatively large air gap that is often present will typically reduce the forces produced for the same electrical power.<ref name=Liasi/> Similarly, the efficiency during generator operation (electric braking/recuperating) with a linear induction motor was reported as relatively low due to end effects.<ref>{{cite journal|last1=Flankl|first1=Michael|last2=Tuysuz|first2=Arda|last3=de Oliveira Baumann|first3=Lukas|last4=Kolar|first4=Johann W.|title=Energy Harvesting with Single-Sided Linear Induction Machines featuring Secondary Conductive Coating|journal=IEEE Transactions on Industrial Electronics|volume=66|issue=6|pages=4880–4890|url=https://www.pes-publications.ee.ethz.ch/uploads/tx_ethpublications/10_Energy-Harvesting-with-Single-Sided-Linear-Induction-Machins-featuring-Secondary-Conductive-Coating_Early-Acces_Flankl.pdf|access-date=4 April 2018|ref=SLIM_Generation |doi=10.1109/TIE.2018.2821637|year=2019|s2cid=53447221}}</ref> The larger air gap also increases the inductance of the motor which can require larger and more expensive capacitors.

However, linear induction motors can avoid the need for gearboxes and similar drivetrains, and these have their own losses; and working knowledge of the importance of the [[goodness factor]] can minimise the effects of the larger air gap. In any case power use is not always the most important consideration. For example, in many cases linear induction motors have far fewer moving parts, and have very low maintenance. Also, using linear induction motors instead of rotating motors with rotary-to-linear transmissions in [[motion control]] systems, enables higher bandwidth and accuracy of the [[control system]], because rotary-to-linear transmissions introduce backlash, static friction and/or mechanical compliance in the control system.
