Shorter project execution times – higher degree of reliability

simotics hvm

High voltage motors employing a modular cooling concept in shaft height 800 mm with power ratings up to 18 MW with welded steel enclosure for applications in sectors such as oil & gas, petrochemical, steel and shipbuilding. Project execution times are sped up as a result of the extremely short delivery times and the fact that these motors can be simply engineered to address the application. Due to the flexible concept, the motor can be precisely adapted to the appropriate application. This is complemented by outstanding reliability, a high degree of mechanical stiffness as well as a weight-optimized and noise-dampening design.

    For compressors in the oil & gas industry, including pipelines, gas storage, air separation and LNG applications, the SIMOTICS HV M motors are available with special coating systems to protect against very humid, salty marine or chemically aggressive environments and are able to comply with Norsok specifications. The SIMOTICS HV M is also available with explosion protection of Ex n (Zone 2) and Ex p (Zone 1) to ensure a maximum degree of safety. Double certification (e.g. with Ex pz and simultaneously Ex nA) can also be implemented on request. The motor is also offered in special designs for low temperatures down to – 50 °C for projects in arctic environments and for compliance with API standards and the associated high requirements regarding vibration quality frequently specified in the oil and gas industry.


    For rolling mill applications in the steel and non-ferrous metals industry SIMOTICS HV M motors
    are available with rated torques of up to 120 kNm, high overload capability and a wide field weakening range.

    For shipbuilding applications such as thruster or main propulsion SIMOTICS HV M motors are available with lightweight and space-saving design especially optimized for ships, quiet, low-vibration operation to enhance the level of comfort on board of passenger vessels, and special coating systems to protect against corrosion caused by aggressive, salty marine environments. This motor is in full compliance with the specifications of leading marine classification societies.
