Magnetic dynamic braking of single-phase asynchronous micromotors using pulsed one-half-wave rectifying current.
Abstract
Two principles of the implementation of magnetic dynamic braking (MDT) are considered. The expediency of using the principle of combined MDT for machines with a power of up to 0.6 kW is shown and the classification of circuit solutions that implement this principle is given. The conclusion is made about the need to analyze the dynamics of the braking mode. By the example of the most effective scheme, the effect of electromagnetic initial conditions on the parameters and nature of the braking process is shown. The dependences characterizing the extreme processes of inhibition are given. The possibility of using the results of the analysis when creating brake devices that control the braking dynamics is indicated.
