Based on a cycle rate of between 24 and 30 shots per hour at the die-casting machine, it is estimated that the hourly requirements for liquid copper will range between less than 140 kg/hr for the smaller rotors to nearly 1,300 kg/hour for the large rotors. More detailed estimates are shown in the Table below.
|Motor Size Range||Liquid Copper Requirements (kg per hour)|
|Less than 1||Less than 1.3||Up to 140|
|1-5||1.3 to 6.5||90 to 225|
|5-20||6.6 to 26||140 to 550|
|20-50||26 to 66||440 to 1,300|
