A classification of the design range of restrictions applicable to the development of controlled asynchronous motors. Use a range of restrictions described in the program automated optimization design of controlled asynchronous motors. Using a range of restrictions significantly affect the results of design synthesis controlled asynchronous motors. Implemented automated optimization design of controlled asynchronous motors. Produced design asynchronous motors, different in design, the degree of protection, cooling method. The most important limitations are the temperature, but it is also possible to use mechanical, dynamic and vibro-acoustic constraints. When designing controlled asynchronous motors functional limitations, which include mechanical, thermal, dynamic and vibroacoustic satisfied throughout the control range. Possible inclusion in the system design model models the most common semiconductor converters and consideration of various types of laws and regulations.
