Combined linear electric motors for robotic systems

Аннотация

The principles of design, construction, and characteristics of special linear electric drives based on combined linear induction motors (CLIMs) for moving robotic trolleys in sealed radiation chambers have been considered. Existing systems have been equipped with gear motors having a cable power supply or chain conveyors. In addition, the mechanisms of electromagnetic coupling have been used. Conventional LIMs with complex control systems or frequency converters are sometimes used in such systems. The proposed construction of electric drives based on CLIMs is much simpler and more reliable. These motors consist of induction driving units and braking units based on permanent magnets. Acting together, these units make it possible to obtain a low speed of trolleys without using any complicated control system or frequency converters. Experimental research and industrial implementation have shown the effectiveness of application of the proposed special CLIMs, the use of which improves the performance and reliability of equipment in a radioactive environment.
