Hello i have done my research and have found varying information relating to the speed at which you must drive a motor to get a desired output and that it is dependent upon back EMF however i am very interested in how much torque i require to rotate the motor.
I have a model aircraft engine and wish to use pulleys or gears to get a good speed and torque to drive multiple brushless motors but i need to work out my ratios for the pulleys or gears (have not yet decided, probably pulleys) can anyone give me any insight.
I am looking for equations to be applied to any brushless motor to calculate the generation voltage, amperage and the required torque based upon any specifications of a motor.
How do I calculate the voltage, current and torque for a BLDC motor? Can I find this information in a datasheet?
