The most common problem in sewage, lift stations and the transfer of solids-laden wastewater is clogging. Fibres, rags, wet wipes and solid pieces quickly lock up a standard submer... More Details

For most applications, an asynchronous motor coasting to a stop on its own after being disconnected from the grid is sufficient. But high-inertia loads (cranes, saws, centrifuges, ... More Details

One of the most critical devices protecting an electric motor is the motor protection circuit breaker (MPCB). An MPCB combines both overload (thermal) and short-circuit (magnetic) ... More Details

The twin-shaft shredder is one of the most demanding motor applications in waste management, recycling and mining pre-crushing lines. Two counter-rotating, knife (hook) shafts tear... More Details

High inertia and high starting current are the two most common challenges when starting IE3 motors direct-on-line (DOL). When you connect an IE3 motor directly to the grid, the inr... More Details

Buying a high-efficiency IE3 or IE4 motor is only the beginning of the savings. The efficiency printed on a motor's nameplate is maintained in the field only when the motor is run ... More Details

Paper and textile factories are, by the nature of their production, facilities that run 24/7 without interruption. A paper machine or a spinning line turns without stopping all day... More Details

Air handling units (AHUs) and ventilation fans account for a significant share of a building's energy consumption and often run for most of the day, even 24/7. This continuous oper... More Details

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
