【 摘 要 】

The article reviles possibilities of a regulated electric drive for increasing the energy efficiency of agricultural mechanisms and pumps. The transition to regulated AC drive can significantly reduce operating costs, both reducing power consumption, and increasing reliability of electric motor, in whose windings currents close to nominal values are passed through sections of starting and braking modes. It has been established that agricultural regulated electric drive of blowing mechanisms consumes energy that is (50-70%) lower than with throttle control and (20-30%) lower than controlled directing devices. The shown effect can be significantly refined if one takes into account that reliability of system parameters in transition regulated AC electric drive increases. The agricultural electric drive, which operates at rated starting currents, according data in, has an increased resource approximately (30-40%).
