This recommended practice outlines the general requirements of a continuous duty, electric motor-driven brushless alternator unit for supplying 400 Hz electrical power to high performance commercial transport aircraft. This specification is for a single motor-generator...
Despite two decades of massive strides in research and development on control strategies and their subsequent implementation, most books on permanent magnet motor drives still focus primarily on motor design, providing only elementary coverage of control and converters. Addressing...
This standard covers the minimum requirements for form-wound and bar-wound brushless synchronous machines for use in petroleum, chemical and other industrial applications. This standard includes synchronous motors and generators with two different rotor designs: salient-pole type...
Users of small electric motors face the difficult task of selecting the best motor for their particular drive application. The technical requirements of the drive, the level of safety needed and the cost factor must all be considered. The choice is made more difficult by the...
Electric energy is arguably a key agent for our material prosperity. With the notable exception of photovoltaic generators, electric generators are exclusively used to produce electric energy from mechanical energy. More than 60% of all electric energy is used in...
