Even can directly measuring such as the no-load voltage of this proving installation generator during, power, moment, rotating speed, noise, temperature rise for each different rotating speeds.Can carry out the test of the dynamic test project such as hypervelocity, overload, power characteristic of magneto.
Because mains frequency is fixed as 50Hz, the rated frequency of dragging motor also be 50Hz, and generally heavy-duty motor is that 4 grades and 6 grades are the most common, and its rated speed is respectively 1500 rev/mins and 1000 rev/mins.The aerogenerator that directly drags rated speed and be 20 rev/mins is unallowed.Essential therebetween speed reduction unit, the just change speed gear box of adding.
So the utility model is at first chosen suitable reduction gear box, when dragging motor is operated in rated speed, just can make magneto realize rated speed.The every electric and mechanical property of the permanent magnet direct-drive generator in the time of at this moment just can testing rated speed.
But this device that reduction gear box only arranged is because dragging motor can only be operated under the rated speed, so the electric property and the mechanical property of the permanent magnet direct-drive generator also can only survey rated speed the time can't be tested the performance when other rotating speeds.
We add the motor variable-frequency speed-regulating device again in system for this reason, and variable-frequence governor can make dragging motor stably be operated under the different rotating speeds.Therefore thisly with the common motor driver of forming of change speed gear box the permanent magnet direct-drive generator stably is operated under the different rotating speeds by variable-frequence governor and drive motor.
