In water supply, cooling towers, fire mains and process feed systems, connecting several pumps in parallel rather than using one large pump is a common engineering choice. Parallel... More Details

In many facilities such as water supply, booster sets, cooling towers, process water and wastewater transfer, groups of several pumps connected in parallel are preferred instead of... More Details

Replacing a failed electric motor in an imported machine looks at first glance like a simple spare-part job; however, if the machine is of North American origin the motor was most ... More Details

The IE5 ultra premium efficiency class, together with synchronous reluctance (SynRM) technology, is setting a new standard in high-speed applications. In spindles (machining work s... More Details

IE4 super premium efficient motors today mostly run together with a variable frequency drive (VFD/inverter), because turning efficiency into real savings is only possible by runnin... More Details

Crane, chain hoist and lifting (hoist) systems push an electric motor into one of the harshest operating regimes in industry. The load is taken from zero to full torque in seconds,... More Details

The vertical shaft impactor (VSI) crusher creates one of industry’s toughest drive applications in sand making and aggregate shaping. At the heart of a VSI is a heavy rotor t... More Details

When buying an IE3 efficient motor we look at the nameplate power, speed and efficiency; yet the critical value that determines how long the motor can withstand a jam, lock or fail... More Details

In three-phase asynchronous motors the most insidious and most common cause of burnout is single-phasing – the loss of one of the three phases. When a fuse blows, a contactor... More Details

When ordering an electric motor we usually talk only about its power (kW) and speed; yet the value that actually defines the motor’s mechanical world is the frame size &ndash... More Details

When buying a pump or fan motor, the catalogue figures most people check are power and speed; yet in a large-impeller fan the real cause of a burnt winding or a protection relay th... More Details

When buying a high-efficiency motor we mostly think of the saving on the electricity bill; but the motor's environmental impact is not limited to the use phase. A motor's life-cyc... More Details

Running an electric motor below its rated frequency (usually 50 Hz) is the most common way to reduce speed with a frequency drive (VFD). But this seemingly simple operation radica... More Details

The synchronous reluctance (SynRM) motor, one of the most common representatives of the IE5 (ultra premium) efficiency class, stands out with its magnet-free rotor and low losses.... More Details

There is more than one way to reach the IE4 (super premium) efficiency class defined by IEC 60034-30-1. One of them is the Line-Start permanent magnet motor, which can run directl... More Details

In an electric motor, vibration and noise are rarely decided by rotor balance alone; they are governed by the mass and rigidity of the housing and by the dynamic behaviour of the ... More Details

When buying an IE3 motor, the most important yet often overlooked element you encounter is the order code imprinted on the motor frame and on the quotation document. Although this ... More Details

In crushing and mining plants, dust is not merely a comfort issue; it is a critical engineering problem that directly affects equipment life, operator health, and legal compliance.... More Details

When you run a new asynchronous motor for the first time, especially while it turns at no load, you may hear a thin, high-pitched whine. Many users mistake this sound for a sign of... More Details

One of the most frequently requested powers in industry is the 3 kW electric motor. It appears across a wide application range, from pumps to conveyors, from compressors to fans. H... More Details
