In pump, fan and blower applications, the most effective way to control flow, pressure and energy consumption is to adjust the motor speed precisely. In most cases a variable freq... More Details

High-efficiency electric motors stand out for their long life and low fault rate in continuously running pump, fan, compressor and process lines. But the most critical maintenance ... More Details

Most three-phase electric motors have a dual-voltage construction that allows them to run at two different voltages by re-arranging the bridges in the terminal box. A motor whose n... More Details

IE5 synchronous reluctance (SynRM) motors — with their magnet-free rotor, high efficiency and drive-coupled operation — represent the ultra premium efficiency class of the future. ... More Details

Large IE4 super premium motors running in continuous processes, pump-fan-compressor lines and critical production plants face the risk that a stator winding fault can destroy the e... More Details

Cast iron framed brake motors are used in conveyors, cranes, hoists and vertical drives where the load must be held safely. They are equipped with a spring-applied electromagnetic ... More Details

Crusher and stone-crushing plants operate not only on hot summer sites but also in cold-climate and arctic regions where winter drops to -40 °C. In crushing-screening plants in Sib... More Details

When selecting a motor in the IE3 efficiency class, only the standard enclosed (TEFC, IP55) frame usually comes to mind. Yet in high-power and special applications, the motor's coo... More Details

How many leads you see when you open the terminal box of an asynchronous motor directly determines what you can do with that motor. In three-phase asynchronous motors, the terminal... More Details

Two-speed (dual-speed) electric motors provide great flexibility in many applications such as fans, pumps, elevators and conveyors by offering two different operating speeds in a s... More Details

The most common assumption in pump, fan and blower motors is that "the higher the IP rating, the better." This is not always true. For a fan motor running indoors in a clean, dry s... More Details

A high-efficiency motor does not merely consume low energy; it also stands out by being quiet, low in vibration and long in bearing life. At the root of these qualities lies a conc... More Details

One of the most insidious mistakes made when mounting an electric motor to the floor or to a machine is soft foot. At first glance the motor seems to sit firmly; all four feet touc... More Details

When selecting a motor to operate in an explosive atmosphere, the type of protection matters as much as the efficiency class. While IE5 synchronous reluctance technology stands out... More Details

An IE4 super-premium motor is designed to run for many years without trouble thanks to its low losses and high efficiency; but to truly obtain that lifetime, you need to see the te... More Details

The real service life of a cast iron electric motor in the field is usually decided not by its winding or bearings, but by the paint and coating system wrapping its body. At a coas... More Details

A crusher motor works in dusty, shock-loaded heavy-duty conditions; and if it is also expected to produce continuous high torque at low speed with a VFD, the motor's own shaft-moun... More Details

200 kW and 250 kW are two powerful motor classes at the heart of compressors, large pumps, fans, mills and process lines in industry. These powers now fall in the range where the I... More Details

The question "soft starter or VFD" on an asynchronous motor is one of the most confused and most often wrongly decided topics in the field. Both devices give the motor a ... More Details

An 800 kW class electric motor is not an ordinary industrial motor; at this power every detail turns into a project line item. The starting method, the cooling type, the frame size... More Details
