I found next matters when a farm motor had drived in drop-voltages. However, the common name of this motor is three phase induction motor of one horse power and the regular voltage is 200 volt in this motor. When the voltage dropped from the regular voltage to 180 volt. (1) The revolution per minute decreased 1.66 percent in rated horse (1 H. P). (2) The efficiency fell off 0.62 percent in rated horse power (1 H. P). When the voltage dropped from the regular voltage to 160 volt. (1) The revolution per minute decreased 3.5 percent in rated horse power (1 H. P). (2) The efficiency fell off 4 percent in rated horse power (1 H. P).
