Efficient Two - Stage Braking Method of Three - Phase Induction Motor |
| Abstract |
In this paper, two-stage braking method of 3-phase induction motor is proposed. This brake involves two stages. The first stage is capacitor self-excitation braking, and the second stage is three-phase magnetic braking. In several applications, a low cost and effective brake is required for three-phase induction motor. A mechanical friction brake, typical braking method for induction motor requires external energy sources which is not safe, expensive and requires maintenance. Static and dynamic analyses of the proposed brake scheme are along with analytical result, simulated waveforms and experimental waveforms are compared. The experimental results shows good agreement with the simulated results. |
