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

A vertical hollow shaft (VHS) motor is a special class of machine used to drive deep-well turbine pumps and vertical line-shaft assemblies, and it follows design rules completely d... More Details

Buying an efficient electric motor often looks like a purely technical decision; yet it is also a finance and accounting decision. A motor appears in the books not as an expense bu... More Details

An electric motor does not only produce power and speed; it also carries a mechanical load through its shaft. A belt-pulley drive applies a side (radial) force to the shaft, while ... More Details

IE5 synchronous reluctance (SynRM) motors offer the highest efficiency class while always operating together with a frequency converter (drive/VFD). This mandatory drive operation ... More Details

22 kW and 45 kW are among the most in-demand power ratings in industry. The vast majority of pump, fan, compressor, conveyor and general drive applications fall exactly into this p... More Details

Picture a conveyor that frequently starts and stops, a press that engages many times an hour, or a process line whose cycle time is measured in minutes. In these applications the m... More Details

The efficiency of a crusher (stone crushing) plant largely depends on how steadily material is fed to the crusher. Weigh (belt) feeders and grizzly (grate) feeders take on exactly ... More Details

Anyone who manages a maintenance store or a spare-motor stock knows it: dozens of motors held separately at the same power and speed, differing only in mounting type, take up space... More Details

One of the most frustrating situations in a plant running asynchronous motors is the entire process stopping after a brief voltage dip or momentary grid outage. Even an interruptio... More Details

22 kW and 30 kW electric motors are among the most sought-after medium-to-large power ratings in industry. In many applications such as pumps, fans, compressors, conveyors, crushin... More Details

In variable air volume (VAV) fan and exhaust applications, the most critical decision is how you control airflow. For years many facilities have throttled fan flow by closing a dam... More Details

A motor being "high efficiency" is much more than an efficiency percentage written in a catalogue; real efficiency is understood by knowing where the losses inside the motor arise ... More Details

An electric motor is not always an energy-consuming element; when the load starts driving the motor, for example while a lift descends, a crane lowers a load or a high-inertia mach... More Details

IE5 synchronous reluctance motors represent the efficiency class of the future with their magnet-free rotors and superior part-load efficiency; however, the most distinct differenc... More Details

When buying an IE4 super premium efficiency class motor, most users focus only on the efficiency percentage and the power; yet one of the most critical acceptance criteria determin... More Details

Before ordering a cast iron framed motor, the first question sounds simple but in practice causes the most mistakes: is the frame of the motor you hold or are being offered really ... More Details
