Hi all,
I am facing problem regarding speed of motor.
My querie is what is the Minimum holding speed of motor and how we calculate minimum speed of any motor.
Motor deatil:---24V DC/4A/6600 RPM

Please share if u can..

Thanks;Abhishek
 

BLDC = BrushLess DC motor, its characteristics are totally set up by the internal IC and the magnetic circuit and the physical loading of the fan and the inertia of the rotor. As you have not got these figures to hand, put 24V on it and its typical load, wind the voltage down until it stops. Then put voltage at zero and increase it to see at what voltage the motor starts.
