Why choose a cast iron IE3 motor

A cast iron frame is stiffer and more robust than aluminium, and it handles heavy-duty and harsh environments well. IE3 Premium Efficiency keeps running costs down on motors that run for long hours. At 93.9% full-load efficiency, the UM3C 225S-4 is rated IE3 on the manufacturer's datasheet.
