Drive for electric displacement of vanes of windpower installation consisting of vanes, whose impact angle to wind can be adjusted by DC double shunt motor, possibly mechanical gearbox

摘要

The drive for displacement of vanes of windpower installation, whose vane impact angle to wind is adjustable by DC double shunt motor, possibly mechanical gearbox, at least one field rectifier (4), and at least single-phase inverter (6).The side shunt coil (5) of DC motor is operated independently of inverter coupled circuit combination, consisting of armature coil (2) of series shunt coil (3) and field rectifier. The DC motor is pref. operated by pulsed inverter. Independent claim is included for application of invented drive.
