What is the alternate current?
An electric current that changes flowing direction. That is, the change of positive pole to negative pole and vice versa together called one cycle. Change of 120 times in a second (negative 60 times and positive 60 times) is called 60 cycles. Generally, the voltage value and frequency of the alternate current is based on the relevant countrys power generation facilities. Japan uses 50/60, US uses 60, and China uses 50. These influence on the performances of motors. Especially, if machines for 60 Hz are used in the 50 Hz area for a long time, the burn out due to the motor overheating can occur. Please be sure to use motors that fit the rating of the relevant power.
