Exciting System Selection for Brushless Synchronous Machine

8th Mediterranean Conference on Power Generation, Transmission, Distribution and Energy Conversion (MEDPOWER 2012), 2012
The 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 ...

Radial Forces in Brushless Doubly-Fed Machines

2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019
This paper investigates the radial forces in brushless doubly-fed machines (BDFMs). The calculation of radial forces in traditional electric machines is reviewed first as the foundation for radial force calculation in BDFMs. The radial force patterns are presented in detail and found to be related to the pole pair combination and supply frequencies ...

CONTRIBUTION TO SIMULATION AND CONTROL PROCEDURES OF BRUSHLESS DC-MACHINES

IFAC Proceedings Volumes, 1977
Abstract The brushless d.c. motor is used in industrial equipment because of its advantages of long life, ability to eliminate brush-wear particles and arcing and high performance characteristic. In order to investigate the feasibility of some control circuits it is useful to simulate the brushless d.c. motor and its electronic commutator by means of

Dynamic simulation of brushless doubly-fed machines

IEEE Transactions on Energy Conversion, 1991
Dynamic and steady-state models for the simulation of the performance of experimental brushless doubly-fed machines (BDFM) are presented. The dynamic simulation results are obtained using a two-axis representation which has been developed from a detailed machine design model.

Simulation of a brushless synchronous machine with an analog computer

Mathematics and Computers in Simulation, 1971
The paper describes the technique of simulating a rectifier bridge in the complete system of a brushless synchronous machine, though the method used is also applicable to any other system implemented with a rectifier bridge. The equations describing the system are set up in such a way that a study on stationary and dynamical behaviour of the machine is
