SYNCHRONOUS MOTORS FOR HIGH EFFICIENCY AND RELIABILITY
Moog pitch motors were developed for the demanding requirements of wind turbines operating under extreme climatic conditions. The Moog pitch motor is an AC synchronous motor with a unique design distinguished by its compact size, low weight and high power density. In addition, the synchronous motor offers high reliability while requiring little maintenance. The motor coating meets the stringent requirements of corrosion protection class C5-M high. Moreover, the motors feature robust connector technology that enables flexible regulation of the motor sensors, making them individually adaptable to customer requirements. With the pitch motors from Moog, energy providers can ensure that their onshore and offshore installations are more efficient, reliable and powerful.
Advantages of the Moog Pitch Motors
- High power density, short response times: The motor's high power density and field-weakening ability ensure a large speed-torque range for dynamic and reliable pitch control – even in the event of a power failure
- Long life, low maintenance: Brushless AC synchronous motor technology, convection cooling and a special, wear-free, lifetime-tested holding brake provide reliable, long service life
- Sensorless control for more reliability: A special rotor design enables reliable pitch motor operation – even without an encoder signal
- Suitable for extreme climatic conditions: Corrosion protection class C5-M high, housing protection class IP65, special interior coating and Gore-Tex® air vents ensure the motor is suitable for extreme climatic onshore and offshore conditions
