In the investigation case of the small-power borehole motors, it is more expedient to discuss the rational parameters of the equivalent circuit but not the optimal ones, because the concrete rated operating point is not fixed due to specific operation peculiarities. Considering the fact, that motor parameters must be matched to the supply circuit, the geophysical cable resistance is accepted as the basic parameter. The basis of optimization algorithm comprises the integral criterion proportional to the motor average electromagnetic power maximization procedure by changing related values of the motor equivalent circuit. So, before starting the initial stage of designing the borehole motor, taking into account the parameters of the supply circuit and maximum borehole medium temperature, agreeably to the computed integral criterion dependences on the related equivalent circuit parameters of the copper-squirrel-cage solid rotor induction motor for borehole investigation devices, it is suggested to choose the rational motor parameters.
