Which power do i need to run a motor as a generator in the following environment? Answered
I want to generate electricity with a rotating axis at a power of 3 Watt. The mechanical torque (depending on the gearbox) on the input axis varies between 0.73 Nm (@ 250 rpm) and 0.122 Nm (@ 1500 rpm).
Currently i am thinking about a synchronous machine, because it yields higher efficiency, but it is very difficult for me to find a synchronous machine fulfilling the mechanical torque regarding the power.
Furthermore i usually just find motors in that size, so i need to turn them around but i have problems understanding the data sheet. For example this motor:
Name: ASM 16
Output Power: 3.1 W
Input Power: 9.2 VA
Rotation velocity: 1000 rpm
As this is a motor, but i want to use it as a generator, should i align the output power from the motor with my input power (the 3 W mentioned above, and than as a generator)?
Can you please give me some ideas how o progress from here?
