Abstract: FIELD: electrical engineering' inductor-motor drives, electric dc and ac multiple-unit trains. 
     SUBSTANCE: in controlling inductor motor operation, motor torque built up by its input phase is found from formula 
     
       
     
     where i in n - 1 , L in  (θ n - 1 , i n - 1 ), and i in n , L in n (θ n , i n ) are currents and inductances of motor input phase at beginning and end of present interval of m ones, respectively. Setting torque of motor input phase is found from formula M set out (θ n + 1 ) = M set  - M in  (θ n ), where M set  is setting value of motor electromagnetic torque during next interval. Desired value of this phase current is found from formula 
     
       
     
     where θ n + 1  is angle of turn of motor rotor by end of next interval; i out  and L out (θ n + 1 ) are current and inductance of motor output phase by end of next interval, respectively; L out (θ n + 1 , i n ) is inductance motor output phase by end of next interval. Motor output phase is energized in beginning of each of m intervals and deenergized as soon as current through this phase attains desired setting value; when M in (θ n ) approaches or exceeds M set  value, supply voltage is not applied to motor output phase and motor input phase is energized in beginning of present interval and deenergized as soon as this phase current is brought to following value: 
     
       
     
     where i in n  and L in (θ n , i n ) are current and inductance of motor input phase at end of present interval, respectively; L in (θ n + 1 , i n ) is inductance of motor input phase at end of next interval. So, currents of motor input and output phases are generated so as to ensure that sum of torques developed by these phases were constant and equal to inductor motor torque specified by instruction or set by speed governor. 
     EFFECT: reduced torque pulsations.
