IMPROVING THE EFFICIENCY OF THE FUNCTIONING OF ELECTRIC MOTORS OF MECHATRONIC SYSTEMS IN A WIDE RANGE OF ROTATIONAL FREQUENCIES
Annotation
Brushless direct current motors (BDCM) used in various robotic and mechatronic systems are considered. A method for analysis and optimization of the motors synthesis is proposed. Results of magnetic field modeling in the electric motor in question performed with the use of the FEMM finite element analysis program are presented. Maintaining a high efficiency of the electric motor in an extended range of rotation speeds is ensured by turning the rotor magnets and introducing an angle of advance for the current supply to the stator windings.
