PERMANENT MAGNET ROTOR AND WIND POWER GENERATOR

Title:

PERMANENT MAGNET ROTOR AND WIND POWER GENERATOR

Document Type and Number:

Japanese Patent JP2004282889

Kind Code:

A

Abstract:

To provide a wind power generator having a high efficiency and reliability, a wide variable speed range and having output characteristics desired for a wind power generation and to provide a permanent magnet rotor for constituting the wind power generator.

The permanent magnet rotor 2 constitutes a permanent magnet rotary electric machine by embedding a permanent magnet 4 in a rotor core 2a and forming a rotor pole 2b. In the permanent magnet rotor 2, changes in the generating end voltage and current of the permanent magnet rotary electric machine respectively fall within a range of 20% in a rotational speed range of 110 to 125% of the rated rotational speed from the rated rotational speed of the permanent magnet rotary electric machine.
