    Sizing an AC motor

    I'm trying to determine the HP I need for an AC motor that will be driving a rotating load of 500 lbs. The rotational speed of the load is 6 rpm, accelaration can be assumed to be 0-6 in 10 seconds. The load is driven by a pulley & timing belt. The driving pulley is 2" and the driven is 20". The...
