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.
When you connect a cast iron motor to a machine, most failures actually begin at the shaft end. If the shaft diameter is not within the correct tolerance, if the keyway is non-stan... More Details
Specifying 12 poles and roughly 500 rpm on a cast iron motor is not an ordinary order. It means the motor will run at very low speed but deliver very high torque, and it is often t... More Details
Lifting a cast-iron motor is not as harmless a task as bolting on a cable or reading the nameplate. When you raise a cast-iron body that can weigh from a few hundred kilograms to w... More Details

Cast iron framed brake motors are used in conveyors, cranes, hoists and vertical drives where the load must be held safely. They are equipped with a spring-applied electromagnetic ... More Details
The real service life of a cast iron electric motor in the field is usually decided not by its winding or bearings, but by the paint and coating system wrapping its body. At a coas... More Details
For a cast iron framed motor working outdoors, in front of a cold store, or in a high-humidity plant, the quietest enemy is not the rain outside; it is the water that condenses ins... More Details
In heavy belt-and-pulley drives, the radial load reaching the drive end (DE) of the shaft can push a standard deep-groove ball bearing beyond its rating. In large fans, crushers, r... More Details

In large cast iron framed electric motors, bearing selection is one of the most critical decisions determining motor life and reliability. While rolling element bearings (ball and ... More Details
The frame of an electric motor is not merely a shell wrapping the windings and rotor; it is a load-bearing engineering component that directly governs rigidity, vibration behaviou... More Details
When you buy a cast iron frame electric motor, the first things on your mind are usually power, speed and frame size. Yet in many heavy-duty applications the decisive detail hides... More Details
In heavy-industry applications where high power and high torque density are demanded together, the ability to reject the losses a motor generates is often the factor that limits th... More Details
In a high-power electric motor, the vast majority of failures originate not from the windings but from bearings that are not properly lubricated. Especially in cast-iron-housing mo... More Details
Picture a conveyor that frequently starts and stops, a press that engages many times an hour, or a process line whose cycle time is measured in minutes. In these applications the m... More Details
Before ordering a cast iron framed motor, the first question sounds simple but in practice causes the most mistakes: is the frame of the motor you hold or are being offered really ... More Details
Crane, chain hoist and lifting (hoist) systems push an electric motor into one of the harshest operating regimes in industry. The load is taken from zero to full torque in seconds,... More Details
In an electric motor, vibration and noise are rarely decided by rotor balance alone; they are governed by the mass and rigidity of the housing and by the dynamic behaviour of the ... More Details
Whether a cast-iron framed motor runs quietly, vibration-free and with a long service life often comes down to a detail you cannot see: the machining quality of the end shield and ... More Details
