Analytical studies of torque motor tape active element

Abstract

Abstract. The paper presents analytical studies of the torque motor tape active element. The tape active element is a novel type of a motor's stator organization, where the conventional winding is replaced by a tape winding. Given the operation principle of proposed active element; its torque characteristics are then computationally found with using the finite element method (FEM). The results show the possibility of the optimal value of the relative electrode width, when the torque will be maximal. The analytical studies of the motor's torque over the number of tape winding coils allowed to receive the recommendations on choosing the number of coils.

Active element influence on the motor’s torque

“…The force F acts on the rotor pole and depends on the flux density B, the tape thickness Δ and the double integral from the distributed current density [12]:…”

The tape winding current impact on the motor’s torque curve

“…In some technical devices, such parameters are permitted. If it is necessary the dependence can be corrected for example by the additional side cuts inside the tape winding plate [6].…”

Parameters of the torque motor tape winding

“…Certain parameters can be obtained directly from the design requirement specification, but other should be determined analytically or by full-scale research. Some parameters have already been considered [7]. The proposed work demonstrates methods of the tape winding coil's number determination.…”
