Why is cast iron used for motor end caps? Is regular iron OK?
Cast iron (Sheng Tie) is low in toughness, good in casting water flow, easy to cast, simple in production process, low in cost, and fully meets the requirement of use.If the use of ordinary iron (Shu Tie), molten iron is too soft, sticky, poor liquidity, complex production processes, high cost, it will not choose Shu Tie casting end cover,
First of all, you should correct your statement. What you call ordinary iron should refer to the steel plate, because the material definition of "iron" refers to pure iron, which is rare. The end cover of the motor is cast iron because the shape of the end cover is more complicated. It is easier to process with cast iron. It is very troublesome to use steel plate. Followed by the cast iron has been fully able to meet the requirements of the motor to the end cap, and cast iron is not easy to deformation.
Regular iron, of course, but the cost of regular iron is too high.The end cover is more loose parts, but the shape is more complex, machining is too cumbersome, difficult, can only be used casting.
