Generators for Wind Turbines

TM4 will custom design your permanent magnet generator for large wind turbines using its leading-edge technologies. TM4’s optimized generator enhances overall wind turbine performance.

Reduced size provides more space in the nacelle
Reduced weight for easier handling
High efficiency over a wide range of speeds
Totally enclosed and brushless machine for improved operation and lower maintenance.

Projects
TM4 is engaged in the scale-up of its technology to 660-750 kW and 1-3 MW.

In the first phase, we are developing a 660-750 kW permanent magnet generator for a wind turbine manufacturer with the following preliminary characteristics:

System Performance

Power: 660 kW @ 1133 rpm
Electrical Efficiency: 97.5%

Basic Mechanical Characteristics

Length: 795 mm (36.6 in)
Diameter: 1020 mm (40.2 in)
Cooling: Water/glycol

In the second phase, we are planning to build a permanent magnet generator targeting the 1-2 MW segment. We have already completed preliminary studies for this generator, which will feature:

System Performance

Power: 1.5 MW @ 1500 rpm
Efficiency: 97.3%

Basic Mechanical Characteristics

Length: 1524 mm (51.6 in)
Diameter: 635 mm (25 in)
Cooling: Water/glycol

We are currently seeking partners to complete the specifications
of the 3 MW generators. If you are a wind turbine manufacturer interested
in learning more or are considering using permanent magnet generators
for your wind turbines, please contact us at your earliest convenience.
TM4 has the skills to assist you throughout your product development process
and supply you with your own permanent magnet generator.
