HV C water-jacket-cooled — high-voltage asynchronous motor with water jacket, 2–11 kV, up to 3.2 MW

Description

HV C water-jacket-cooled is a compact high-voltage asynchronous motor of the HV C series with water-jacket cooling (cooling method IC71W). The water jacket of the housing removes heat directly into the coolant circuit, so the motor can be fully enclosed: contaminated outside air does not enter it, and the dissipated heat can be used to raise the overall efficiency of the system. Thanks to exceptionally high power density, the motor has very compact dimensions and low mass, and it is intended above all for places with limited space. The motor is rated up to 3.2 MW at a rated voltage of 2–11 kV (a low-voltage version is also available), shaft heights of 315–560 mm and 2–8 poles. The degree of protection is from IP55 to IP66, and the motor is fully insensitive to dirt, chemicals and salt fog. It runs on direct-on-line start from the grid and from a frequency converter; general-purpose versions and versions for zones 2 and 22 (Ex ec, Ex tb) are produced. The compact and light design reduces noise and vibration levels, which ensures smooth operation and lower maintenance costs, while high efficiency provides quick payback through electricity savings. The manufacturer notes an extended service life and expanded digital capabilities: connection to Inspire IQ increases operating transparency and system performance. Typical applications are thrusters and main propulsion electric motors of ships, agitators, compressors, pumps and rolling mill drives; the industries are shipbuilding, metallurgy, pulp and paper, chemical and mining. High-voltage motors are produced at plants in Nuremberg and Berlin (Germany), Drasov (Czechia), Tianjin (China), Mumbai (India) and Norwood (USA), and more than 2000 service specialists worldwide provide service.
