NONREVERSIBLE TWO-PHASE THYRATRON-INDUCTOR MOTOR Russian patent published in 2005 - IPC

Abstract RU 2266604 C1

FIELD: electrical engineering; improvement of thyratron-inductor motors.

SUBSTANCE: proposed nonreversible two-phase thyratron-inductor motor has salient-pole symmetrical stator 1 carrying concentrated windings and unwound rotor 2. Stator 1 has eight poles and rotor 2, four ones. Surface of rotor 2 has three steps over its length, angular width of each step being b_SR = b_ZR/3 = b_ZS, where b_ZR is angular width of rotor pole; b_ZR is angular width of stator pole, and lengths of first, second, and third steps are as follows: l₁ = 1/3 l; l₂ = 2/3 l; l₃ = 1, where l is rotor length; each of two phase windings A and B incorporates four series-connected coils.

EFFECT: enhanced torque due to mutual induction of phase windings, reduced counter emf in transients and reactive power.
