How can quickly adjust motor performance in place -

If can quickly adjust motor performance in place
the method of first selection is voltage adjustment method, is the motor and the rated load, adjusting the working voltage of motor, until the speed of the motor to meet the design requirements of speed, then this is the working voltage of the machine is not rated voltage of the motor, the ratio of the two voltage for K. So can adjust the motor winding circle number, according to the proportion of the motor in the rated working voltage of motor performance meet the design requirements.
