  ●The Calculation of RPM output revolving number is to use RPM number in the same period and use the number as a criterion and then divided by reduction ratio.
●Due to the difference of weight loading the real RPM output revolving Number might be different.
●The "□" in the type name means reduction ratio of reduction gear, if willing to get bigger reduction ratio at 180 please purchase another reduction gear that reduction ratio at 10 and use them arrange in pairs.
●In the culumn of the table which has colored means the shaft of reduction gear runs the same direction as motor runs, the others are not.
