Study of electric drive with indirect control of output mechanical variables of asynchronous motor

The article describes the analytic dependences of mathematical description of indirect control of an asynchronous motor’s electromagnetic torque and angular velocity methods with a device of indirect control of the output mechanical variables. These dependences allow us to calculate the values of electromagnetic torque and angular velocity of asynchronous motor and to provide its continuous control to guarantee the given technological parameters in different operation modes of industrial mechanisms. The paper provides the block diagrams of indirect control device of output induction motor mechanical variables that are realized by means of a mathematical description of calculation method of electromagnetic torque and angular velocity with different accuracy. The experimental research results are shown. These results approve the validity of the suggested mathematical description for the indirect control of output mechanical variables of asynchronous motor methods with a device of indirect control device for asynchronous motor of industrial mechanisms with frequency control.
