Title: Green economic pulse motor
Post by: gverlab on June 24, 2016, 09:32:46 PM
Ukrainian public research laboratory of alternative energy GverLab presents our very perspective energy saving green project «Pulse motor with reduced reverse EMF and  with a modular electronic control system» .
Pulse motor with reduced reverse EMF refers to irreversible electric machines of direct and single-phase alternating current is applied in all industries and transport, the proposed motors have a higher efficiency and a number of advantages over the known electric engineі. Motor works on the principle of running pulsed magnetic field stator, has a special stator winding, which is wound multicore heavy gauge wire , designed for low voltage (12-72 V) , with a standard squirrel cage induction motor. Generation of pulsed signals and switching of running pulsed magnetic field produces special modular control system for high-power transistors, with a recovery system. Our pulse motor with reduced back EMF saves  50-60% of electricity. The power of current experimental prototype motor is 7.5 kW, 1,500 rpm. Perspectives : in 2016 planned to get a patent and  build, test a series of pulse motors  5, 10, 15, 20 kW with different modular control systems.
Application: for electric vehicles, industrial fans, for replacing standard motors in machines, production lines.
The video shows the work of pulse motor - prototype 7.5 kW, the most energy efficient engine operation is reached under partial load at 300-500 rpm, a voltage - approximately 48 V, a current - about 5 A, the consumed electric power  - about 250 watts , (see fragment1 of video - from 20 to 30 seconds and  fragment2 of video - from 46 to 53 seconds).
