Overview wind power generators Synchronous and asynchronous generator, Yaw drives

Asynchronous generators Advantages for our customers VEM Sachsenwerk GmbH is worldwide active in various industry sectors and among other things puts focus on the development of machines for wind power generators. Due to our highly efficient calculation and construction departments the wind power generators are made to custom with regard to the individu- al user requirements at which our development departments collaborate closely with partners in science and research. This results into products which belong to the technological leaders on the market and set standards for the product...

Asynchronous motors – low voltage Yaw drives As a full liner for induction machines VEM also offers low voltage machines for wind power generators. The AC asynchronous brake motors are characterised by excellent operational reliability, long lifetime and efficiency. Their modifiability permits that our drives can be used universally. High reduction precision drives are used in drive technology for highest requirements with regard to torque and speed. For these high capacity reduction drives for many years now we produce brake motors, which act as actuating drives for yaw drives. Wind parks...
