For a contracting, EPC or engineering firm, project-based electric motor supply is an entirely different process from buying a single motor. Here, tens or sometimes hundreds of mot... More Details

For someone looking at an electric motor nameplate for the first time, abbreviations like kW, rpm, IE3, IP55, IM B3, class F, S1 and cosφ read like a foreign language. Yet each of ... More Details

At first glance, an electric motor proforma or quote looks like a single number. Yet behind that number lie dozens of line items: efficiency class, frame material, mounting type, p... More Details

As power demand grows in industrial facilities, engineers inevitably face a critical technical decision: beyond a certain point, should you continue with low voltage (LV) motors, o... More Details

As solar investments become more popular, many business owners aim to lower their electricity bills with a self-consumption PV plant (solar power plant) installed on their roof or ... More Details

The IE4 efficiency class represents one of the highest practical efficiency levels industry can reach with electric motors, and it sits on the agenda of every facility that wants t... More Details

The most important, yet visually hardest to detect, difference that distinguishes one cast-iron framed electric motor from another is casting quality. Two motors may be of the same... More Details

What actually turns a machine is not power, but torque. A common shorthand in engineering is to refer to motors only by their kilowatt value; yet two motors marked "22 kW" in a cat... More Details

Selecting the motor for a boiler feed water pump is a far more critical engineering decision than choosing a motor for an ordinary centrifugal pump. A boiler feed water pump draws ... More Details

When choosing an asynchronous motor to drive a high-inertia load, there is one parameter most purchasing decisions overlook: the load moment of inertia J (kgm²). A large fan impell... More Details

On an electric motor, the fan cowl and protection guard often look like a small line in the catalogue, yet they directly determine the motor's lifetime, operating temperature and o... More Details

One of the most critical steps determining the field life and trouble-free operation of an electric motor is the correct mechanical fixing of the motor to the floor or base. Even a... More Details

In crusher and mining plants, the ore carried on the feed conveyor frequently contains so-called tramp iron: broken excavator teeth, bucket tips, bolts, nuts, tool fragments and we... More Details

When an IE3 electric motor arrives at the facility, the delivery and acceptance inspection done before opening its box and storing it prevents many problems that could arise later.... More Details

An efficient electric motor is concerned with energy not only when it drives the load, but also at the moments it brakes or decelerates the load. When a crane lowers a load, a cent... More Details

When ordering an IE4 super-premium efficient electric motor or replacing an existing motor, reading the nameplate (label) in full is the strongest barrier against an incorrect deli... More Details

When replacing a cast iron framed motor or coupling it to a drive, the most frequently overlooked yet most critical dimension is the shaft height, that is the H dimension. The H di... More Details

The IE5 synchronous reluctance (SynRM) motor is the most common representative of the ultra-premium efficiency class in the field, and unlike a classic asynchronous motor it can ne... More Details

In chemical, pharmaceutical, water treatment and surface-finishing plants, transfer pumps that carry acids, bases, solvents and corrosive chemicals work in one of the harshest envi... More Details

The efficiency value (%) written on the nameplate of an asynchronous motor shows the best point reached at full load. But in real plants motors rarely run at full load; most of the... More Details
