Launch and control circuit systems built on traditional devices represent complicate multi-link system. Its liability is determined by a number of intermediate devices. Launch jaggedness – is one of the significant flaws, negatively affect on launching process dynamics. Promising direction of launch and control circuits devices are rheostats built on high current semi-conduct polycrystalline thermistors. At the article short analysis of electrotechnical devices launch processes is given. A power engines launch process with thermistor rheostats is considered and formulated a number of limits. Graphic dependences characterizing launch current and rotating moment at direct launch changing and with rheostats on thermistors are given. An example of launch current for asynchronic engine with phase rotor calculating is given as well.

Keywords: semiconducting thermos-resistance, launch rheostat, launch currents curves, generalized constant, automation.
