MPSF: permanent-magnet synchronous machine up to 15 MW (wind turbine generator / drive), up to 1 kV
MPSF is a low-voltage synchronous machine with a permanent-magnet rotor rated up to 15,000 kW and a voltage up to 1 kV. It is used as a generator in wind turbines with a full-power frequency converter, with or without an AFE active front end. The second area of application is high-torque drives.

Description
In wind power, turbine makers are gradually moving from doubly-fed generators to permanent-magnet machines, and the MPSF belongs to exactly this class. Among PM generators, the manufacturer singles out the medium-speed MS PMG, which work paired with a medium-speed gearbox. Such generators are more compact, have high efficiency and put less load on the drivetrain mechanics. The machines are designed for wind turbines up to 15 MW, including offshore. Stators for offshore generators up to 14 MW are assembled at the group's plant in Bosnia.
Shaft torque is 20,000–400,000 Nm. Fed from the converter, the machine works in the range 0–1800 rpm, and the IEC frame sizes cover 500–1250. The stator winding is made with insulation class F or H, and the enclosure protection is up to IP54. Heat is removed by a water jacket or a heat exchanger, air–water or air–air, depending on what is available on site. Standard mounting arrangements are IM B3 (IM1001) and IM B14 (IM3601), others are agreed on request.
The rotor of the manufacturer's PM machines comes in two types. In the first, the magnets lie on the surface and are held by a bandage. In the second they are embedded in the rotor core, and such a machine makes better use of the field-weakening region. The stator winding is made as a distributed two-layer winding or a concentrated one, the latter having shorter end windings. Permanent magnets are sensitive to overheating, mechanical shock and incorrect supply of the winding, so protection against these conditions is built in at the design stage. The temperature sensors in the winding and the protection logic of the converter depend on it as well.
Onshore and offshore versions are available. For drive tasks a compact version in the form of an integrated generator plus drive unit is supplied on request. The machines are made to IEC 60034, and on request also to CSA C22.2 and UL 1004. The package includes temperature and vibration sensors, encoders and radial shaft seals. Outside wind power the MPSF is installed on extruders and other high-torque machinery.
In a request for machine selection, specify at once the output and torque, the speed range, the type and parameters of the converter, the cooling method, the mounting arrangement and the acceptance standard. For wind turbines add the installation conditions (onshore or offshore turbine) and the dimensions of the seat in the nacelle.
