Electric Pitch Hub

Essential technical and troubleshooting skills are a must for the maintenance and operation of wind turbines, and Lab-Volt leads the way in providing the training that will develop these required skills. The Lab-Volt Electrical Pitch Hub Trainer features all the components typically found in the hub of a commercial wind turbine. The trainer includes a servomotor with its drive, a slewing bearing, two limit switches and a representation of the wind turbine blade. A SIEMENS PLC controls the different functions of the Electrical Hub and is located in an electrical enclosure, with all the other electrical components. The enclosure features a transparent window to allow component identification, and transparent protective guards with electric interlocks ensure safe experimentation while working around the trainer. Control modes are accessible using the full-color touch screen operator panel, and a password protected display allows the instructor to insert electrical faults for troubleshooting activities.
