摘要
FIELD: electricity.;SUBSTANCE: in the method of suppressing the torque pulsations of a four-phase valve jet engine, the first group of the torque thresholds is set in the interval [0°, θR/4] of the rotor positions. The second group of the torque thresholds is set in the interval [θR/4, θR/2] of the rotor positions. Power is applied to adjacent phases A and B to excite them. The supply of phase A excitation power exceeds the supply of phase B excitation power by θr/4. The entire switching process from phase A to phase B is divided into two intervals. In the interval [0°, θ1] of the rotor positions for phase A, the second set of the torque thresholds is applied, and for phase B, the first set of the torque thresholds is applied. Critical position θ1 arises automatically during the commutation process, thus eliminating the need to perform any additional calculations. The total torque is controlled in the range [To+th2low; To+th2up]. In the interval [θ1, θp/4] of the rotor positions for phase A, the second group of the torque thresholds continues to be applied, and for phase B, the first group of the torque thresholds continues to be applied, with the total torque being controlled in the range [To+th1low;To+th1up].;EFFECT: ensuring the suppression of torque pulsations in a four-phase valve jet engine and high technical performance.;2 cl, 3 dwg
