ABB M3AA 100 LA 1065RPM 400V DC Brake Motor

ABB M3AA 100 LA 1065RPM 400V DC Brake Motor is an ABB yaw-brake motor from the M3AA family, specifically configured for wind turbine yaw control and identified by the variant M3AA 100 LA; it is associated with Vestas yaw brake installations, where the motor serves as the braking actuator in the turbine’s yaw system, converting electrical signals into controlled brake engagement. The unit is specified as a 3P (three-phase) drive with a nominal power of 1.75 kW (2.34 HP) and a rated speed of 1065 RPM, and it is designed to be driven from a 400 V DC braking supply to activate and release the brake. With the M3AA 100 LA designation, this model represents a particular size/variant within ABB’s DC-brake motor offerings, delivering the necessary torque and braking responsiveness for reliable yaw actuation in wind-energy installations. This combination—3P drive, 1.75 kW (2.34 HP), 1065 RPM, and a 400 V DC brake supply—defines the performance envelope buyers reference when matching the M3AA 100 LA to ABB and wind-turbine yaw control configurations.
