Difference between ТА and ТВ, ТА - heat resistant, ТВ - heat and water resistant. So it should be near same.

Here is also some translated description:
DG-0.5TV motor-generator is a two-phase unit with a hollow non-magnetic rotor.
The phase shift between the supply voltage of the field winding and the control winding of the motor must be done using special circuits that provide an electrical angle of 90 ° regardless of the motor load.
The DG-0.5TV mount is flanged.
The operating mode is continuous, reversible.
The supply voltage of the field windings of the motor and generator is 36 V, the control windings are 30 V.
The supply voltage frequency is 400 Hz

Explanation of the symbol of the DG series:
- D - engine; G - generator;
- number - maximum motor power, W;
- TA - heat resistant; ТВ - heat and moisture resistant; ТЧ - heat and moisture resistant to a supply voltage frequency of 1000 Hz.

Here is also book about this motors, but sure it is russian: https://web.archive.org/web/20121101022409/http://www.motor-remont.ru/books/book2/book2p20.htm

I will translate relevant part:
In automatic control systems, engine generators (DG) are widely used. The engine generator is an assembly consisting of an electric motor and a tachogenerator. Currently, there are ДГ, which include a DC motor and tachogenerator, a two-phase asynchronous controlled motor and a direct current tachogenerator, an asynchronous motor and tachogenerator, a two-phase controlled asynchronous motor and a synchronous tachogenerator.

The unit may also include a gearbox. In some cases, DGs are equipped with interchangeable gearboxes with different gear ratios.

For accurate calculating devices, tachometric alternating current generators are used, consisting of a ТГА with a linearity of the output characteristic of 0.05 - 0.1% and a residual EMF of 15 - 50 mV, and a two-phase controlled motor.

For tracking systems with tachometric DC feedback and accurate integrating DC drives, ДГ are used containing two-phase controlled asynchronous motors and ТГП.

For tracking systems of low accuracy, ДГ are produced, consisting of a ТГА and an asynchronous two-phase motor with hollow rotors. The linearity of the output characteristic of such ДГ is about 1%, the residual EMF is 100-200 mV.

<< this was translated before >>

The supply voltage of the motor and generator excitation windings is 36 V, the control windings are 30 V. The supply voltage frequency is 400 Hz, ДГ-Т4 type DG is 1000 Hz.

The diagram of the connecting of DG series motor generators is shown in Fig. 18.16, the main technical data are in the table. 18.18, overall and installation dimensions and mass - in table. 18.19 and in fig. 18.17.

try to ask it at russian aviaforums
