In the article proposes methods of increasing the maximum torque of built-in direct current torque motors by varying their design (the diameter of the armature winding wire; the dimensions of the armature in order to increase the number of conductors located on its outer surface; by changing the winding scheme) while maintaining the connection dimensions, which is an urgent task when designing or modernizing electric motors for autonomous transport devices. A number of calculations and experiments were carried out, the analysis of which showed that when the diameter of the winding wire increases, the resistance of the armature winding decreases and, as a result, the starting torque increases, the power consumption and losses in the armature winding also decrease. But at the same time, the starting current at a constant voltage increases by more than two times, which requires an increase in the installed capacity of the power source. Increasing the diameter of the armature allows you to increase the number of conductors and the cross-section of the armature copper while simultaneously reducing the width of the magnet and reducing the magnetic flux. As a result, the starting torque of the electric motor decreases. It is shown that changing the winding scheme can significantly complicate the technological process of manufacturing a simple loop winding and a complex multi-pass wave winding with a larger number of parallel branches and can create problems with the commutation of the armature winding. The work confirmed that increasing the diameter of the winding wire is the most effective and least expensive way to increase the maximum torque of built-in DC torque motors with excitation from permanent magnets and a slotless armature design, which have found their application in devices of autonomous objects (platforms). At the same time, changes are made only in the design of the anchor - the diameter of the anchor iron is reduced and the number of turns in the section is reduced. The magnetic system, brush-collector unit, bearing shields (if available) remain structurally unchanged.
