2 BLDC motors on one shaft with the same drive?

    Hey guys,

    I'm new to this site, and am a university student studying Electrical and Electronics engineering. I just completed a design project controlling a BLDC motor (pretty low powered at 60V, and giving output rpm of about 6000rpm). Now I had an idea where instead of using a single BLDCM for an application, would it make sense to put two identical BLDCMs on the same shaft, in order to give double the output torque? I would operate the two using the same drive as I would use for one, but I'm still unsure of how to take into account a lot of my efficiency calculations. I have a feeling that this would just draw double the power (if not, then only provide half the output power to each motor).

    Please help me out. I need some answers ASAP for an important project.
