Możliwości oszczędzania energii w napędach małej mocy

In this paper a new construction of the motor of small ventilator has been presented. Thanks to application of new neodyme magnets in the motor, it was able to obtain high efficiency of the motor. Such high efficiency allows ventilator to spare much more energy as compared to ventilator fitted with traditional asynchronous motor. However a new motor requires an application of electronic supplying system. At the assumption of constant price of the energy, the cost of this solution is reimbursed after four years. It was predicted that the energy drawing by individual receivers could be diminished by 2MW.
