In continuously running heavy-duty applications such as pumps, fans, compressors and crushers, a 90 kW or 110 kW class motor alone determines a large share of the plant's energy bi... More Details
No matter how well a cast iron electric motor is wound, if the surface its feet sit on and the machining of its foot-mounting holes are not correct, the motor will come back from t... More Details
In a crushing plant, sizing and classifying the material is just as critical as the crushing capacity itself. At the heart of this task sits the vibrating screen, which separates r... More Details
One of the most critical and highest-value pieces of equipment in any plant is the main drive motor. 315 kW and 355 kW ultra-large-power electric motors appear in cement mills, lar... More Details
Selecting an asynchronous motor by looking at a single torque figure in a catalogue can lead to a serious starting problem when the load has high inertia. Many engineers only check... More Details
A 160 kW or 200 kW electric motor is no longer an off-the-shelf purchase; it is an investment decision. In this power band, selecting a motor does not end with saying "I need 200 k... More Details
Wastewater transfer is one of the most demanding pumping duties in domestic and industrial sewage networks. Liquids carrying rags, wet wipes, plastics, hair and long fibrous waste ... More Details
In an industrial facility, the largest share of electricity consumption comes from electric motors that run day and night. The efficiency of these motors now affects not only the e... More Details
Pharmaceutical and drug production is among the most strictly regulated manufacturing environments in the world. Every piece of equipment used in a room where an antibiotic tablet,... More Details
Demand for continuous, stable torque at low speed is one of the most challenging engineering problems in modern industrial drive systems. Extruder lines, mixers, crane hoisting mec... More Details
In industrial plants, motors in the 132 kW and 160 kW class are the most critical and highest-value equipment forming the backbone of production lines. A correct choice in this pow... More Details
The most critical mechanical interface that transfers an electric motor's power to the driven machine is the shaft end. No matter how high the motor's rated torque is, this torque ... More Details
In crusher and washing plants, one of the most critical links in the process chain is the sludge dewatering stage. The fine-grained waste produced during stone crushing and sieving... More Details
The speed of an electric motor is as fundamental to selection as its power. Two motors of the same kW value offer very different torque and very different operating characteristics... More Details
The most critical factor in whether an asynchronous motor can move a hard load is often an overlooked detail: rotor slot geometry. In machines that demand high starting torque such... More Details
At the very bottom step of the three-phase asynchronous motor family stand two power values that often fit in the palm of a hand: 0.06 kW and 0.09 kW. Do not let their small power ... More Details
Shelters and NBC (Nuclear, Biological, Chemical) protective structures are designed around a ventilation philosophy that is entirely different from ordinary buildings. In these str... More Details
In industry, electric motors are responsible for most of the energy consumed in a facility, which makes them the strongest lever for energy efficiency investments. Replacing old, s... More Details
A paper mill or pulp plant is one of the most demanding operating environments for an electric motor. Along the line there is water vapor, heat, chemical mist and fine fiber dust; ... More Details
The days when a motor only consumed energy are over. While a crane lowers its load, a centrifuge decelerates, or an inclined conveyor carries material downhill, the motor actually ... More Details
