Abstract:
An electronic locking system including a lock cylinder having an electronically actuable release assembly which is selectively enabled to disengage a pin from a cylinder plug, to permit the rotation of the plug by an inserted key. The lock cylinder and key each contain non-volatile, electronically alterable memory devices, such as EEPROM integrated circuits, which house keying system codes. The key EEPROM is preferably housed within the key blade, in a key design which closely resembles a traditional mechanical key without the usual bitting. The release mechanism incorporates a locking pin which is moveable between plug-engaging and non-engaging positions, along a radius of the lock cylinder. The release mechanism may include a primary actuator which directly moves the locking pin, or may act indirectly upon the locking pin via a latching member.
Abstract:
A power transmission system for a wind turbine comprises a gearbox and generator. The gearbox includes a gear-box housing and gearbox output member. The generator includes: a generator housing having a drive-end side and non-drive-end side, the drive-end side being coupled to the gearbox housing; a stator supported by the generator housing; a rotor coupled to the gearbox output member so as to be driven thereby; a non-drive-end shield coupled to the non-drive-end side of the generator housing; and at least one auxiliary drive mounted to the non-drive-end shield. The at least one auxiliary drive is configured to rotate the turning gear. A corresponding method of installing a wind farm including such a power transmission system is also provided.

Abstract:
The present invention relates a device for magnetizing and assembling an electrical machine comprising a stator and a rotor with at least one permanent magnet, the device comprising a magnetizer unit for magnetizing the at least one permanent magnet of the rotor, a rotor load unit and a translation unit for translating the rotor from the magnetizer unit to a rotor load unit for inserting the rotor into the stator. The invention also relates to a method for magnetizing and assembling an electrical machine comprising a stator and a rotor with at least one permanent magnet at a magnetizing unit.
Abstract:
Apparatus and methods to magnetize and demagnetize the magnetic poles of a rotor assembly for an electrical machine, such as a generator. The apparatus and methods provide for individually magnetize magnetic domains in the permanent magnetic material of the magnetic poles of a rotor assembly of the electrical machine after the electrical machine is installed in a larger assembly. The magnetization system may be used to magnetize and demagnetize the magnetic poles while the rotor assembly is connected with a prime mover, such a rotor of a wind turbine.
