One of the most common solutions for moving air in ventilation ducts is the duct-type (in-line) axial fan. These fans consist of an impeller placed in a circular housing and an ele... More Details

When you start an asynchronous motor, at the first instant it draws a current from the grid far above the rated current; this inrush (starting) current rapidly heats the winding un... More Details

The frequency drive (VFD) is the most common way to adjust the speed of an asynchronous motor, and it delivers major energy savings in applications such as pumps, fans and conveyor... More Details

When you buy an electric motor and bring it to your plant, connecting it straight to the machine and running it can be one of the most expensive mistakes. A motor that has been str... More Details

Dewatering is one of the most critical yet least discussed systems in mines and quarries. Water that collects in galleries, on the overburden bench or at the pit floor becomes a sl... More Details

Does "IE3" on a motor's nameplate guarantee that the motor is really in the IE3 efficiency class? The answer is yes if there is a test and a certificate behind the nameplate, and o... More Details

When a plant invests in an IE3 or IE4 high-efficiency motor, the expectation is clear: less loss, a lower energy bill. But even when the motor is correctly chosen, if the quality o... More Details

Plastic extruders and continuous process lines are among the most demanding applications for an electric motor: the motor turns 24 hours a day, often seven days a week, at a high a... More Details

The quality of a cast iron framed electric motor is hidden not only in its winding and efficiency class but in how its frame is machined. Two motors with identical catalogue values... More Details

IE5 synchronous reluctance (SynRM) motors run noticeably cooler than asynchronous motors of the same rating. The main reason is the rotor design: a SynRM rotor has no cage bars, no... More Details

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
