According to the spec sheet, this stepper motor is rated by torque values. The torque values are measured in units of gram-force * cm (g-f * cm). For example: with a 15g weight hanging on the end of an arm 10cm from the motor shaft, the corresponding weight would be calculated 10*15 = 150 g-f * cm of torque. These little 5V stepper motors are probably good for 170-190 g-f*cm pull-in (step) load max, and 950-1050 g-f*cm pull-out (holding) load max. Hope this helps. Show

How strong is a stepper motor?Stepper motors generally are not available in frame sizes larger than NEMA 34, with most applications falling in the NEMA 17 or NEMA 23 motor sizes. As a result, it is unusual to find stepper motors capable of producing more than 1,000 to 2,000 ounce inches of torque.
How do you calculate the load capacity of a stepper motor?To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.
