Micromaster 440 Motor Drive

The Siemens Micromaster 440 Drive, 6SE6440-2UD34-5FA1 is a 45 kW, 90 A, 380/480V AC drive and is part of the extensive Micromaster 440 range. This Motor Drive is a variable frequency drive and has advanced vector control, suitable for an extensive range of applications including fan and pump control. A motor drive feeds electricity into the motor in varying amounts and at differing frequencies, controlling the electric motor’s speed and torque. The capable Motor Drive can also control the ramp-up and ramp-down of a motor during stop and start sequences reducing the mechanical stress in motor control applications.

The clever design and advanced vector control of this Drive separates the MicroMaster 440 series from the rest of the MicroMaster family. The advanced features of this motor drive make it suitable for applications such as elevators, conveying systems, hoisting equipment, textiles and machine build and many more.
