Description
HV C air-cooled is a compact high-voltage asynchronous motor with air cooling from the High Voltage Compact Motors series of the manufacturer (a former division, an independent company since 2024). The HV C series covers powers from 150 kW to 7.5 MW and is intended for applications where small dimensions, reliability and low maintenance costs are important. The motors are built on a single platform together with general-purpose and explosion-protected versions, which reduces design, procurement, spare parts and staff training costs. The air-cooled variant is rated up to 2.5 MW at a rated voltage of 2–11 kV (a low-voltage version is also produced), shaft heights of 315–560 mm and 2–8 poles. The housing has an improved cooling system with fins and tubes (cooling methods IC411 and IC416): according to the manufacturer, this gives up to 20 % more power in the same frame size, increases the service life of components and does not increase the motor dimensions. The design is optimized for low vibration levels. The degree of protection is from IP55 to IP66. The motor works both on direct-on-line start from the grid and from a frequency converter, and it is produced for non-explosive areas and for zones 2 and 22 (Ex ec, Ex tb). Project adaptation to a specific application is possible, as well as connection to the Inspire IQ platform for predictive maintenance based on IIoT data. Typical applications are pumps, fans, compressors, conveyors and mills in the oil and gas and chemical industries, water supply and wastewater treatment, fiber production, shipbuilding, power generation and cement production. High-voltage motors are produced at plants in Nuremberg and Berlin (Germany), Drasov (Czechia), Tianjin (China), Mumbai (India) and Norwood (USA).
