This series motors amount to the sixteenth frame sizes. Among of them, the frames and end-shields of the frame size from H63 to H132 are made of cast iron or aluminlum-alloy,and the frames of H160 or over are made of cast iron with sufficient mechanical strength.All cooling ribs of mo-ors assume verical or horizon-tal dlstributlon.So,the motor entirety looks very beautiul.
The terminal boxes are made of cast iron aluminium-alloy die-casting for frame size H63 up to H280 or high strength cast iron for H315 up to H450 and located on the top or a side of the motor for offering users choose.
