Active element influence on the motor’s torque

Abstract

Abstract. The paper presents the numerical and experimental studies of the influence of the torque motor active element on the motor's torque. The tape active element is a novel type of a motor's stator organization, where the conventional winding is replaced by a tape winding. The force (torque) dependence over the rotor pole position using COMSOL is given; the tape winding resistance and the turns number are defined. The relative motor's characteristics are investigated and the maximum torque over the certain poles pair number is obtained. The application of the proposed active element in brushless DC motor is considered. The results show the possibility of the further synthesis of the torque motor.

Torque motor tape winding characteristics and its connection with design parameters

“…Besides, as shown previously [6][7][8], the magnetic flux density also depends on the pole pairs number of the magnetic system. Also in [6] it is indicated that for a given tape width the value of the double integral ) , , ( 0 I y x D remains practically constant when the pairs of poles number of the magnetic system changes.…”
