METHODOLOGY FOR CALCULATING PARAMETERS AND ENERGY CHARACTERISTICS OF ELECTRIC MACHINES WITH A CLOSED LOOP

The article is devoted to the consideration of issues related to the design of electric motors and the use of submersible electric machines in the marine environment on drilling rigs and platforms. The article describes the calculation of parameters and energy characteristics of asynchronous electric motors of submersible electric machines. The mathematical apparatus for calculating the active resistance of the stator phase, the winding of a short-circuited rotor in asynchronous electric motors is given. Some characteristic features of the calculation of asynchronous electric machines of open design are also considered when calculating the active resistance of the rotor winding and the stator phase, taking into account the voltage and current transformation coefficient at rated load.
