Stopping a pump or fan motor looks trivial at first glance: you cut the power and the motor stops. Yet on large-diameter pipelines, high-head centrifugal pumps and heavy-impeller f... More Details

Buying a high-efficiency motor is only one part of energy saving. Whatever voltage the motor is supplied with in the field, its real efficiency is shaped by that voltage. Most plan... More Details

In electric motors running on a variable frequency drive (VFD) there is a danger invisible to the eye that quietly kills the bearing: bearing current. The drive's fast switching cr... More Details

The synchronous reluctance motor (SynRM), one of the strongest representatives of the IE5 (Ultra Premium) efficiency class, stands out by offering high efficiency and high torque d... More Details

In high-power applications, motor selection demands far more engineering than for small powers. At ratings such as 90 kW and 110 kW the motor is no longer a "shelf product"; it is ... 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

Crusher (stone crushing) plants present one of the harshest working environments in industry: high impact loads, constant dust, heavy oscillations and long running hours. Under the... More Details

In electric motor supply, demand concentrates heavily in the small-to-medium power band, and within this band the 2.2 kW IE3 motor, the 3 kW IE3 motor and the 4 kW IE3 motor are by... More Details

One of the most frequently misunderstood concepts in induction motor selection is the service factor (SF). Appearing as a small number on the nameplate, this value defines the shor... More Details

The small-power band, comprising 0.55 kW, 0.75 kW and 1.1 kW electric motors, represents the most frequently demanded range across industrial, agricultural and commercial applicati... More Details

Fan selection in air handling units and ventilation systems has undergone a fundamental change in recent years. Traditional scroll-housing fans are increasingly being replaced by f... More Details

Buying a high-efficiency motor is only the beginning of the saving. The IE3 or IE4 efficiency value printed on the nameplate belongs to the new motor leaving the factory. Yet as th... More Details

Stopping an electric motor is often a more demanding engineering problem than starting it. In applications where free coasting is not enough and the machine must stop in a very sho... More Details

Explosive atmospheres are one of the most sensitive areas of electric motor selection. In facilities containing gas, vapour or combustible dust, a motor's surface temperature, spar... More Details

In small-power induction motors, efficiency is the parameter most often overlooked yet most impactful over the long run. Motors that fit IEC 80 and 90 frames, such as 0.75 and 1.1 ... 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

Running a crusher is a very different task from turning an ordinary pump or fan. Because of the heavy wheels, flywheels, and large rotating masses of the breaker, the motor encount... More Details

30 kW and 37 kW IE3 motors sit right in the middle of the medium-upper power class most demanded by industry. These two powers are practically a cornerstone for compressors, pumps,... More Details

When you decide to run an asynchronous motor with a variable frequency drive (VFD), the control mode the drive will operate in is a question at least as important as the motor itse... More Details

A 355 kW asynchronous motor sits at the point where industrial large-power class begins and supply planning becomes as important as the purchasing decision itself. At this power a ... More Details
