When an electric motor arrives on site, one of the first things to do is to lower, handle and place it safely at the installation point. This seemingly simple step is actually a cr... More Details

Consider two IE3 motors: both rated at the same kW power, both in the same efficiency class, both from the same brand. Intuitively, you would say "they do the same job." Yet these ... More Details

Selecting the main drive motor of a ball or rod mill in a mineral processing plant, cement factory or ore grinding line is very different from an ordinary motor selection. A mill l... More Details

Knowing which of the dozens of motors in a facility comply with the current efficiency regulation is a critical question both for legal compliance and for energy cost. The answer t... More Details

Can there be two different motors in the same efficiency class? Yes. The IE4 Super Premium efficiency class can be achieved both with classic asynchronous (squirrel-cage) motors an... More Details

When selecting a motor for a machine operating under heavy shock loads such as a crusher, press or mill, the most frequently debated topic is the frame material. The reason cast ir... More Details

The most common mistake when ordering an IE5 synchronous reluctance (SynRM) motor is to think of it like a classic asynchronous motor. In fact, IE5 synchronous reluctance motors ma... More Details

When you buy an electric motor, the first number on the nameplate is usually the purchase price; yet the real cost of that motor to your facility over its lifetime goes far beyond ... More Details

One of the most effective ways to cut the energy bill in pump and fan plants is, instead of running the motor at fixed speed and throttling the flow with a valve, to reduce the mot... More Details

"Should I switch to an IE4 motor, or is IE3 enough?" is one of the most frequent questions businesses ask in this period of rising energy costs. The correct answer is not always "t... More Details

Selecting an electric motor in food, beverage and pharmaceutical plants is very different from selecting an ordinary industrial motor. In these plants the line is washed at the end... More Details

When buying an asynchronous motor, most businesses carefully study the power (kW) and efficiency class (IE3/IE4) but overlook the "cos phi" value on the nameplate. Yet the power fa... More Details

When buying an asynchronous motor, the labels "insulation class: F" and "temperature rise: B (80K)" on the nameplate tell you far more than the rated power figure. These two values... More Details

If you want a fan to run at two stages, "fast" and "slow," an elevator to slow down as it approaches a floor, or a conveyor to carry material at two different speeds, and you do no... More Details

If you find yourself asking "why does this drive need such a low speed?" on a mixer, a cooling tower fan or a slow-rotating large drum, the answer is very often a 12-pole very low ... More Details

400 and 450 kW electric motors represent the top class of the low-voltage asynchronous motor range. These powers are no longer products taken off a shelf and delivered; they are pr... More Details

There is only a twenty-five percent power gap between 200 kW and 250 kW; but this relatively small difference seriously changes the motor's frame size, weight and delivery process.... More Details

1.5 kW and 2.2 kW are the two most-used mid-range power classes in industry; from pumps to fans, from conveyors to small machines, you encounter these motors in countless applicati... More Details

When electric motors are mentioned, large powers often come to mind; yet a very large part of industrial automation runs on motors in the smallest power class. The 0.12 kW (approxi... More Details

In cement factories, the end of the production line is the packing and bagging section where the product becomes bags and pallets. This section is one of the dustiest and harshest ... More Details
