摘要

Soft irons and steels play a major role in the magnetic circuits in electric motors. They form the path that allows magnetic flux from the windings to interact with the flux from the permanent magnets in all types of PM motors. The same magnetic process functions with "squirrel cage" ac induction motors as well. The reluctance type motors depend on the soft iron members in rotor and stator in combination with their unique tooth geometries to create mechanical power in the form of motor shaft torque and speed. The dc magnetization (first quadrant B-H saturation) curves are used to establish the flux carrying capability of the various types of irons and steels used as magnetic flux collectors and conduits for completing the magnet flux paths inside an electric motor when driven from a dc source. Core losses composed of eddy current based losses and hysterisis losses provide information on how the magnetic iron or steel reacts to the rate of change of input voltage and current excitation patterns best represented by high frequency PWM signals. Many applications today require electric motors to run at speeds well above 10,000 rpm. Motor commutation switching frequencies in these high motor speed applications can exceed 1000 hertz in these higher speed applications. Magnetic material losses will rise exponentially under these conditions. Controlling and minimizing these losses is critical to successful motor designs. Historically, it has been difficult for the motor design engineer to obtain information on the magnetic properties of soft iron and steels for use in the newer finite element and finite boundary motor design simulation program. Members of EMERF and SMMA recognized the need for a single comprehensive source for technical information about the magnetic properties of soft irons and steels. This database is the outcome of many discussions, visits, phone calls, e-mails, etc., over the past 3 years. This database is a collection of information provided by a wide range of soft iron and steel suppliers and lamination providers. The information has been cataloged, reformatted, and transferred to a CD-ROM. Every effort has been made to provide correct and user friendly data for the motor design engineer. EMERF and the materials suppliers assume no liability for the use of this collected reference and cataloged data. It is a "user friendly" aid in the design of electric motors.
