Why is double speed motor low speed r current and high speed current?
Double speed motor no-load start, the initial starting current should be low speed, high speed current is small; after no-load start up, it is possible to lower the speed of the current than the high speed, because the low speed lubrication conditions are poor;
Two speed motors should be of low speed, high speed and small current when carrying the same load.5) there is a point, later ask questions, please describe a smooth, do not be so hasty, if it is not to see Chen always back to you, I do not want to answer.
1) the supply voltage is the same, when the output power is certain, the current of the low speed motor must be large;2) the supply voltage is the same, the output torque must be certain, the high speed of the motor is certainly high;
