    Low-speed motors (PM, PMH, PMT, SPMH)

    The three-phase low-speed induction or synchronous motors with permanent magnets are designed for direct (gearless) drives of axial fans in cooling towers. The motors are supplied from either the 50Hz mains or static frequency converters. They are intended for environments with ambient temperatures up to 60°C.
     


    PMH/D; PMT/D Series


    PMH/D; PMT/D Series

    The three-phase low-speed vertical induction motors are designed for direct (gearless) drives of axial fans in cooling towers. The motors are intended to be supplied from the 50Hz mains. The motors are 180/90 rpm switchable and they are intended for environments with ambient temperatures up to 60°C (PMT version). They are available also as single-speed motors (without D in designation).




    PMH/I Series


    PMH/I Series

    The three-phase low-speed vertical induction motors are designed for direct (gearless) drives of axial fans in cooling towers. The motors are supplied from static frequency converters. They are intended for environments with ambient temperatures up to 60°C.




    PM Series


    PM Series

    The three-phase low-speed vertical induction motors with power outputs 4.8 kW and 8 kW are designed for direct (gearless) drives of axial fans in cooling minitowers. The motors can be double-speed motors for direct supply from the 50Hz mains. At request, the motors can be made for supply from static frequency converters.




    SPMH Series


    SPMH Series

    The low-speed vertical synchronous motors with permanent magnets on the rotor with power outputs from 8 to 200 kW are designed for direct drives of fans in cooling towers. The motors are supplied from static frequency converters. The increased efficiency in connection with infinitely variable speed control enables to achieve electric power savings of up to 30%.
