I have system I want to move with a DC motor that requires about 1 kW of power when taking into account rolling resistance, drag resistance and when moving on an inclined plane with a specific velocity. I had trouble finding small enough motors to provide that power so I asked a friend for help and he told me to use a gear system with low power motors.
So I ended having a question in my mind: Does the motor power, say a 1 kW motor, need to match the 1 kW requirement of the system or is it the torque provided by this motor that needs to match the torque of the system I want to move, in this case ((9.55 * 1000 kW)/ 600 rpm) = 15.91 Nm? If it's the torque then that means I can use a 200 W with known torque and a gear system to multiply the torque and match that 15.91 Nm requirement? If it's the power then is my only option using enough motors to match that 1 kW value, say 5 200 W motors? I'm sorry if the question is not totally clear, I'll do my best answer any questions.
