| description | Relevance of the research is caused by the capability of monitoring output parameters - impact energy and frequency of synchronous impact electromagnetic machine. Such machines transform directly electromagnetic energy to a moving head mechanical work impulse. The operation cycle is implemented by the system of two windings providing direct and reverse impact mass acceleration by electromagnetic forces. According to the proposed scheme variant the impact nodes have been made for the electromagnetic hammers IE-4207, IE-4210 and the electromagnetic perforators IE-4709, IE-4724, ERP-1000 applied in building and construction works. In spite of the fact that the mentioned scheme is wide-spread and well-known for a long time the electrical energy conversion to mechanical work for the total operating cycle was not analyzed in details. The main aim of the research is to analyse energy transformation in a two-winding synchronous electromagnetic machine with head inertia reverse. Research methods are based on application of electromechanical system energy balance equation and its separate components over the impact electric drive total operation cycle. Results and summary: Due to implementation of operation cycles using the two-winding magnetic system and head inertia reverse the impact mass is accelerated forward and backward by electromagnetic forces for two power supply voltage pulses. The known control method allows reducing electric drive effect on power grid, and provides electric drive stable operation in a wide range of head from tool withdrawal factor. A new method of controlling electromagnetic machine is proposed on the basis of energy transformation analysis. The proposed method differs from the known one in using three power-line voltage pulses during the operation cycle. The new control method helps impact energy increase, reducing electric drive influence on the power grid. |
