Traction motors

Aim:

• impartation of basics of the traction motor calculation and design

Content:

• design of electric machines (asynchronous machine, partially in reference with direct current machine)
• calculation of magnetic circuits
  • principle calculation procedure
  • calculation of characteristic sections of the magnetic circuit (various cross section, trapezoidal teeth, tooth relief)
  • sections with changing magnetic flux
  • sections with non-constant induction
  • determination of the magnetisation or idle characteristic curve
• design of windings
  • types of windings
  • general laws of AC-windings
  • conductor split in the winding concept
  • single-shift and double-shift winding
  • winding factor
  • winding choice
  • harmonic waves suppression with winding pitch reduction (chord of winding)
• principle concept development of a traction motor
• calculation of reactance
