Why are you running the motor without a load for it?
Please have a look to the datasheet: https://datasheet.octopart.com/RK-270SH-16175-Mabuchi-datasheet-15250217.pdf
Why are you running the motor without a load for it?
Hi,
Datsheet says " voltage 9.0V"
The RPM of this DC motor mainly depends on applied voltage.
The current of the motor mainly depends on torque.
Usually you run a motor by applying a "voltage", only a few applications use current control.
--> apply a voltage, and the current doesn't need to be controlled.
In the chart you see the relationship between torque, RPM and current with a constant 9V supply.

Hi,
Why don't you read the datasheet.
It says I_max = 0.7A.
With your propeller and 9V you overload the motor.
Klaus
Hi,
True.
There are two motors in one datasheet -RH and -SH..
Indeed the -RH is rated for 4V.

ok actually when i am connecting a 10" propeller its not working with 9v 1 AMP but working fine with 5v 2 AMP
so is it all ok to apply 9v 2 AMP ?
What if connect 9v & 3 or 5 AMP ??
so from where to get such motors ? I am about to design a single prop unit just to lift up the module i am designing & its lighter than a drone & equivalent to a helicopter containing a battery a small microcontroller , connectors etc
I buy radio control products and their replacement parts from my local hobby store. The brand I like is www.e-fliterc.com . But I think you are in India which is very far away from my Canada and E-Flite's company is in America.
A one-prop drone? I once imagined I could make a simple one-man helicopter. I would attach a propeller to a motor, hold it over my head, and rise into the air. Just 10 or 20 feet high because of the power cord. As I dreamed, however, I realized that the propeller would spin in one direction, and I would spin in the opposite direction. No go.
A conventional helicopter needs the tail rotor for stability. Helicopters require time and skill to learn to pilot them. Toppling is easy and often destructive (unless your craft has oversize skis attached).
You hope to make an experimental helicopter from scratch. It's a big challenge. Find out what motors they need, including watt consumption, speed, battery size and quantity, etc.
Your motor probably would work okay with an airplane of the proper size. Do you have experience with airplanes or 4-prop drones?
