Excitation Control of a Brushless Synchronous Motor
IEEE Transactions on Industry Applications, 1984A simple system is presented for controlling the excitation of a brushless synchronous motor independently of the motor speed or load angle. The system comprises a pulsewidth modulated (PWM) inverter provided with controllable pulsenumber. Experimental measurements of the induced rotor excitation shows that a wide range of excitation control is ...

Exciting System Selection for Brushless Synchronous Machine
8th Mediterranean Conference on Power Generation, Transmission, Distribution and Energy Conversion (MEDPOWER 2012), 2012The paper deals with the special brushless synchronous electrical machine (SBSM) working with an extensive variable load. It's exciting systems usually keep cosφ ≈ 1. Among them are unmanned deep-well oil pumps drives, wind renewable energy SBSM, etc. The SBSMs usually works in harsh climate conditions, where thyristor or IGBT exciting systems are not ...

A Two-Stage Brushless Excitation Method for Hybrid Excitation Synchronous Generator
IEEE Transactions on Magnetics, 2015A two-stage brushless excitation method for hybrid excitation synchronous generators (HESGs) is proposed in this paper. Comparing with the traditional three-stage brushless excitation method, the auxiliary exciter is eliminated. The complete self-excitation is realized. As the main generator of two-stage brushless generation system, a tangential/radial

Model development and validation of brushless exciters
2015 IEEE Eindhoven PowerTech, 2015This paper describes the process of performing site tests and model development of brushless exciters. Brushless exciters are often a source for model inaccuracy when studying synchronous machines and excitation system, which may lead to incorrect stabiliser design and poor performance.
