Just in case - here is how you can calculate the power from the torque and RPM. A couple of quick notes: Torque is force times length - kg is not a force but a mass. If the "torque" is given in kg*cm - then this is not a proper torque number. It should be in Newton*cm. Newton is the unit for force and kg for mass. The force a mass experiences here on earth is the mass multiplied by the earth's acceleration of the mass in the earth's gravity. This acceleration is 9.81 m/s/s (meters per seconds squared). This unit is the same as N/kg (not that readily visible - but for now we'll just accept that as correct). Now we can calculate the proper torque by multiplying the two numbers: 4.5kg*cm * 9.81 N/kg = 44.2 N*cm. Power is work done per time - work, energy and torque are identical units of measure - force times length - the continuously delivered torque is the same as the work done by the motor. However, for the power to be correct we have to express work in N*m (SI units) - not N*cm. So we have translate N*cm into N*m. 100 cm = 1 m or 1cm = 0.01 m. We can just simply replace the cm with 0.01m and well get the torque (work) in N*m - 4.42N* 0.01m = 0.442 N*m. Next: power is Nm/s in SI units - that means we have to express 100 rpm in rps (revolutions per second = rev/sec). 1 min = 60 seconds. 100 rpm = 100 revs per 60 secs = 100/60 rps = 1.7 rps. Now we can calculate the power in N*m/s: 0.442N*m * 1.7 rps = 0.74N * m / s = 0.74W of mechanical power - which is even less power. Of course that's only correct if the 4.5kgcm number is correct for the motor. Some of the suggestions were to use the electrical power of the motor to estimate the mechanical output power. That too is a legit approach - however, that power setting given must be under the same conditions for which the mechanical output was given. E.g. the motor must run at 100 rpm and deliver the torque given - only then the current draw by the motor and the voltage accross the motor can be used to calculate the approximate mechanical power. For example - if the motor draws 1A at 12V when stalled out (motor is slowed down to a stop), then this is not the same condition as running the motor at 100 rpm. Sometimes the specifications given for those products can be a bit questionable. **Q: Can this fit into a 1/4” metal rod? With a shaft collar or something?** A: If you are widening a coupler and you can, use a drill press or milling machine. Be sure the setup is as rigid as possible. Use a "reamer" 1/4" in diameter if you can get one. They are special purpose tooling but get used all the time for this exact job. They cost a few dollars. Use very low speed or even turn the chuck by hand. Do not use a hand dill at full speed with a twist bit. I would rather use 400 grit sand paper or fine abrasive padding than any sort of standard drill and bit. **Q: How many rotations does this motor make a minute** A: As stated on the label.... 100 revolutions per minute (rpm) **Q: Is this brushed or brushless?** A: this is a brushed motor ## Customer Reviews ### ⭐⭐⭐⭐⭐ Just as expected *by M***Y on 14 September 2024* just like as described in the photos and description. works for me. ### ⭐⭐⭐⭐ Nice motor, good size. *by M***S on 2 June 2023* Unfortunately it stalls on low speed, hence to fast for my application ### ⭐⭐⭐⭐⭐ Motor - super *by C***P on 27 June 2026* Super Motor .
