Abstract:
An apparatus and method for the installation and removal of permanent magnets in a permanent magnet electromechanical machine, for example a wind turbine power unit generator. A magnet holder is mounted on a magnet carrying structure such as a rotor. Permanent magnets may be inserted into and removed from the magnet holder after the electromechanical machine is assembled. In this manner, permanent magnets may be installed on the magnet carrying structure by an interference fit, without using bolts or adhesives, to facilitate both assembly and removal for maintenance and repair.
