Motor Parameters unsure about units

Hi There

I ordered the 34:2 25D DC Motor with encoder as well as the 150:1 Micro Gearmotor from you and just want to clarify something regarding the motor parameters. You mention in the Specifications Tab for example the Kt is the stall torque divided by the stall current. What are the units? Is the torque in kgcm and the current in mA? And for Ke, is the motor speed in rpm?


Sorry, I meant the 34:1 25D DC motor


As you mentioned, the torque constant is given as torque per current. You can use the units you like (we provide stall torque in both oz-in and kg-cm). However, when you use the constant in other calculations you will want to make sure its units match the other values in the calculation.
