Warm note:Our products are divided into two packages. Specification:Name: AC gear motorRated voltage: 110VRated speed: 0-135 RPMReduction ratio: 1:10（10K）Torque: 3.8nmPower Phase: single-phaseShaft diameter：12mmgeared motor size：139MM * 90MM *74MMReducer size: 41*90*74mmPacking list:1 x motor1 x reducer1 x speed controllerIn order to reduce the inapplicability of the motor, please judge according to the selection process before placing the order1. Judge the deceleration range first1) The speed is within the safe speed range (e.g. 315-450r), choose the wattage according to your actual load 2)The speed is outside the safe range (such as 100-450r), choose 2-3 times of your actual load（For example, if you want to choose 100-450R 15W motor, now you need to choose 30-45w motor）2.Judge load1) Load product ＜1m，If the torque is 10nm, the load is generally ≤ 10kg 2) Load product ＞ 1m, please consult us3.Continuous working time of motor1) Continuous working time of motor＞4h, Wattage selection needs to be increased (For example: if you want the motor to Continuous work 5h, you need to choose lager watts than your actual load watts) 2) Continuous working time of motor＜4h, Wattage selection no needs to be increased4.Judge the installation form (2 kinds in general)1) Directly use the output shaft to drive the load [that is, the load is directly forced on the shaft, which is generally judged by comparing the data in the table, and the difference is not big] 2)second, Motor as a power source to drive a whole equipment [there are many accessories, such as roller, pole, etc.], which we usually need to match 1-2 times larger. (For example, if you choose the second installation way, you want 15W motor first, now you need to choose
