cross section of the working segments layer in the rotor gap is determined by the formula equ2 equating both formulas for s we will find the value of u03bd which is rounded number of the expression hence we can obtain the desired value of the cross section of the upper end face winding determining dimensions of the rotor cores on the other guideway sections where the winding turn length l t is less than l tm and is variable the bus thickness i e the size of the working segments along the stator must be reduced proportionally to l t leaving the bus width w b u221a s bm invariable and equaled to g 2 u03b4 the permissible current i p in the air gaps of pmlsm is the maximal propulsion force of the linear motor as a whole is where q is coefficient considering the shift of the rotor poles and non sinusoidal distribution of the winding turns of the phase winding the scheme of the complete left side winding with u03bd 4 is shown in fig3 when the vehicle begins to depart the station it employs wheels rotated by the direct current motors which are supplied with power from constant voltage busbars located on the concrete beam of the guideway in these sections the winding turn length of.
