Electromechanical properties of micromotors

Abstract

The article presents a comparative analysis of electromagnetical features of new generation servomotors with ironless rotor. The torque and power increasing factories are considered. The electromagnetic time constant of different motors size is calculated and analysed, the ratio of electromechanical and electromagnetical time constants is considered. Electromechanical features are compared with those of former produced motors features. The thermal constants are considered. Results of comparitive analysis of electromagnetic features allow to represent servomotor as first order system.
