i am using a 12v 1000rpm johnson dc geared motor .it says that It gives a massive torque of 10Kgcm. i dont understand the term 10kgcm.. as in from this how can i predict that upto how much weight can i load the motor.. without the loading effect on the supply?
plz reply as soon as possible.
 

mmm, i'm not really sure, but i always take that number as "well powered, it can hold 10Kg if they will be hanging at 1cm of distance (to the center of the edge), or 1kg at 10 cm distance [or 100g at 1m well, maybe not so much.]"

hope someone else can answer this.
 

More likely this is the torque you can get for the rated
winding current, on some thermal or reliability basis. The
manufacturer's web info might have more detail on the
basis.

Kg-force can be converted to newtons giving you a
m-n torque.

you can visualise torque in this way.
remember torque spec specifies the maximum load you can connect.

10Kgcm--->at the shaft imagine a disc of 1cm radius. you can connect 10kg load at the circumference.(10Kgx1cm=10Kgcm)
or
a disc of radius 2cm. then it have load of 5Kgcm.(5Kgx2cm=10Kgcm)

likewise, can have 4Kg on a radius of 2.5cm.

so finally what you connect/couple to the motor , take its radius and find the max.load.
