In high-power electric motors, the frame is not just a shell that houses the windings; it is the load-bearing structure that determines the motor's rigidity, vibration damping, hea... More Details

An old asynchronous motor that has been running in your facility for years may still appear to do its job. Yet IE1 or IE2 class motors quietly lose money every operating hour when ... More Details

Dosing chlorine, a coagulant or a pH-adjusting chemical drop by drop in exactly measured amounts at a water treatment plant, or adding a precise additive according to a recipe at ... More Details

The most common way to connect an electric motor directly to a pump, fan, gearbox or any machine is a coupling. Seemingly a simple part, the coupling is actually a critical bridge... More Details

The most demanding moment in driving a large crusher or mill electrically is the first start after the machine has stopped. Tonnes of rotating mass, the flywheel and the crusher j... More Details

Before installing an IE3 motor in the field, the first question to answer is simple but often skipped: have I correctly selected the cable, fuse and contactor for the current this... More Details

When you open the electricity bill of a pumping station, the consumption you see cannot be explained by the motor efficiency alone. Most operators think "I bought an IE4 motor, so... More Details

IE4 Super Premium motors carry a high efficiency value on their nameplate; but that value belongs to the condition where the motor runs near full load. In real facilities motors of... More Details

The rated power of electric motors is determined against a standard reference condition: usually 40C ambient temperature and up to 1000 meters altitude. When the ambient temperatur... More Details

The drive motor of a long, heavy-load belt conveyor is one of the most critical and most stressed motors in a facility. This motor usually runs under continuous (S1) full load, wit... More Details

Pumps, fans and compressors are the three applications that make up the largest share of an industrial facility's electricity consumption. These systems mostly run under continuous... More Details

Moving to an IE5 (Ultra Premium) efficiency class motor in the small-power band of 7.5 kW and below is a decision many facilities face but rarely answer with confidence. IE5 motors... More Details

When buying an asynchronous motor, one of the quantities most facilities overlook, yet which causes the most trouble in the field, is the starting current. At the first instant of ... More Details

Vertical multistage pumps are the standard solution for applications demanding high pressure, such as high-pressure water supply, building pressurisation (booster) systems, reverse... More Details

When an electric motor arrives on site, the first critical step before installation is lifting it and moving it into place safely. Especially in medium and large-power cast iron bo... More Details

When buying an IE3 efficient electric motor, most buyers look only at the kW power and the speed. Yet the quantity that really determines whether the motor can drive the load, alon... More Details

Ball and rod mills sit at the heart of mineral and ore grinding plants, and they are heavy-duty machines expected to run without interruption. The main drive motor of these machine... More Details

Knowing which of the dozens of motors in a facility comply with the current efficiency regulation is a critical question both for legal compliance and for energy cost. The answer t... More Details

Can there be two different motors in the same efficiency class? Yes. The IE4 Super Premium efficiency class can be achieved both with classic asynchronous (squirrel-cage) motors an... More Details

When selecting a motor for a machine operating under heavy shock loads such as a crusher, press or mill, the most frequently debated topic is the frame material. The reason cast ir... More Details
