The speed in the table is calculated by dividing the reduction ratio by (50Hz; 1500r/min, 60Hz: 1800r/min) as the base number. To obtain a higher speed ratio than the following table, you can install an intermediate reduction box with a reduction ratio of 10 between the motor and the reduction box, and the reduction ratio will increase by 10 times. The rated torque in the table is calculated by the motor rated torque x reduction ratio x transmission efficiency. If the actual working speed of the motor is lower than 200r/min, please derate the rated torque x 50%. The maximum allowable torque of the reduction box is 3N.m
