When a motor will work in a dusty place, under high vibration or heavy load, the body material alone settles most of the decision. The cast iron frame exists precisely for these conditions: it is far more resistant to impact, shock and temperature than a lightweight body. At HEM Motor we produce our cast iron body motors in-house and deliver from stock, offering a durable option for heavy-duty applications.
Another advantage of cast iron is that it conducts heat well, so the motor stays cooler even under heavy load and failure risk drops. Our sector motors run from 0.55 kW to 355 kW, with a Ø100 mm shaft diameter on the largest frame. IP55 protection and Class F insulation are standard across the range, and slip near full load is about 4%.
A lightweight body is advantageous for small powers and portable jobs, but cast iron comes to the fore in heavy fields such as mining, cement and crushing plants. For general use, also see our industrial motors. For model selection to suit your site, current stock and a quote, call +90 (532) 345 49 86 or use our contact page.
