In crusher and stone-crushing plants the motor works in an extremely demanding environment: the load is continuous, impact-laden, and can at any moment meet an unexpected jam or f... More Details
90 kW and 110 kW are two common steps in the large-power class in industry. These powers appear in heavy applications such as large pumps, industrial fans and aspirators, compress... More Details
The great majority of asynchronous motors have a squirrel-cage rotor; these rotors are simple, robust and maintenance-free. But in applications with high inertia, demanding heavy ... More Details
The 1.5 kW electric motor is one of the most sought-after and most frequently stocked small power classes in the market. It appears in countless applications, from small pumps to ... More Details
In fan and exhaust (aspirator) applications, the impeller is often mounted directly onto the motor shaft end. In this directly coupled arrangement, with no belt-and-pulley interme... More Details
What sets a high-efficiency electric motor apart from its rivals often hides in details invisible to the eye. One of them is a simple part spinning at the back of the motor that m... More Details
The rated power of an electric motor, the value printed on its nameplate, is valid at a specific reference ambient temperature: usually 40 degrees according to the standards. When... More Details
IE5 class synchronous reluctance (SynRM) motors are becoming increasingly common in industry thanks to their magnet-free rotor design and ultra-premium efficiency. But the operati... More Details
An IE4 class electric motor, thanks to its high efficiency, produces the same output with fewer losses; this means lower winding temperature and longer life. Yet this thermal marg... 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
Crusher and stone-crushing plants are among the toughest sites for electric motors. Alongside dust, vibration and shock loading, the most sudden and destructive threat, often overl... More Details
45 kW and 55 kW motors sit in industry's most in-demand medium-to-high power class. Frequently found in pumps, fans, compressors, conveyors, crushers and line drives, these ratings... More Details
When an induction motor must be placed far from its supply, the cable length is a parameter often overlooked yet it causes two separate, serious problems. The first, in grid-fed sy... More Details
Motors in the 560 kW and 630 kW class sit at the upper limit of the low-voltage induction motor world. At these ratings you are no longer making an ordinary purchase but managing a... More Details
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
