Abstract
The paper describes the construction and principle of operation of a permanent-magnet-excited linear oscillatory motor. As part of an automated frequency adaptive drive, the motor is suitable for driving smaller resonance mechanisms.7 It points out the prerequisites for the use of permanent magnets in the construction of the motor and shows the advantages of the Alnico types of material. The demagnetisation effect, which is controlled by shielding the magnets, is estimated. The magnets may be designed for the standard operating mode. Finally, the components of the magnetic field of the motor are analysed and used for the determination of the main parameters of the magnetic circuit of the motor. The basis for the determination and optimisation of the motor characteristics is given in the references to other papers by the authors.
