Special asynchronous motors: submersible cryogenic and for drilling rigs

Description

Besides the standard high-voltage HyMD series, the range of asynchronous motors includes two special directions: submersible cryogenic motors and motors for drilling rigs. Both types are built on the same design principles as the company's general-purpose machines: electromagnetic, structural and vibration calculations are performed with CAD/CAE, and production relies on experience of manufacturing electric motors since 1910. A submersible cryogenic motor is intended to operate directly in the pumped liquefied medium, as part of a submersible pump unit; such solutions are used at liquefied gas storage and transfer facilities. Motors for drilling rigs are intended to drive the mechanisms of oil and gas drilling rigs. The manufacturer notes general experience of operation with 50 and 60 Hz networks and a range of asynchronous motors up to 13.8 kV and up to 25,000 hp; specific parameters of the special versions are not given on the website and are determined from the customer's technical specification. For selection, it is necessary to specify the type of working medium and temperature, the required power and speed, the voltage and frequency of the supply network, the starting method (direct-on-line or from a variable frequency drive), explosion-protection requirements and standards. The position is presented as a product direction; technical characteristics are clarified with the manufacturer.
