Abstract
The paper considers the features of a tape winding torque motor development. Novel motor type allows to obtain an increased torque by the high current flowing through the tape winding. It is shown that the most effective way of the torque increasing is the tape winding plate resistance reducing.
Highlights
At present, torque motors are used in technical systems as the gearless drive base
The analysis shows that the specific characteristics of Russian torque motors are worse than foreign analogues
Where is the tape thickness; U is the power supply voltage; R is the plate resistance; B( ) is magnetic flux density created by one pole; N is the number of winding turns; r f is the tube frame radius; D(x, y, I0) is a double integral over the surface of the magnetic flux action
Summary
Torque motors are used in technical systems as the gearless drive base. The torque motor has a modular structure, consists of two separate assembly units: a rotor and a stator. Torque motors can be improved by using new magnetic materials, changing the rotor design or using new types of windings. In this case the specific characteristics increasing can be achieved by the torque raising due to the high current flowing through the rotor winding.
