Comparison of load-carrying capacity of enclosed asynchronous motors in S3, S4, S5 recursive short-time modes
Well-posed calculation algorithms for permissible stator winding current in an enclosed asynchronous short-circuited rotor motor in S3, S4, S5 recursive short-time modes are introduced, calculation for a number of several explosionproof motors in these modes made subject to stator winding temperature fluctuations. Load-carrying capacities of motors of various output and rotation frequency are compared in the S3, S4, S5 modes.
