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

It does not matter how high quality an electric motor is if the terminal connection is not made correctly. A significant share of motor failures and fire risks comes not from the m... More Details

Among the equipment that feeds material flow in mining and crushing plants, the apron (plate/chain) feeder stands out. Positioned in front of the crusher, beneath the bunker or at ... More Details

In mining and ore beneficiation plants, the flotation cell hosts one of the most demanding motor applications. The flotation agitator and aerator motor runs continuously, twenty-fo... More Details

The most common cause of an IE3 motor burning out is overheating; when overload, single phasing, frequent start-stop or inadequate cooling pushes the winding temperature above the ... More Details

Assessing a facility's energy performance by looking at the efficiency of a single motor falls short; the right measure is the energy spent per unit of product produced. This measu... More Details

When an IE4 super premium motor fails, the first question is usually the same: "Should I rewind it or buy a new one?" On a standard motor, rewinding is often a reasonable option; b... More Details

Cast iron body electric motors are painted in a specific shade of grey as standard; however, for many projects, OEM machine builders and bulk buyers, the colour of the motor is not... More Details

IE5 synchronous reluctance (SynRM) motors offer an advantage that is often overlooked alongside their ultra premium efficiency: noticeably quieter operation. In HVAC plants near ho... More Details

Drawing water from a deep well requires a special motor that operates underwater, meters below the surface: the submersible pump motor. Unlike surface pumps, this motor is lowered ... More Details

The power stated on an asynchronous motor's nameplate assumes a balanced (symmetrical) three-phase supply. In a real grid, however, the voltages of the three phases are often not e... More Details

Taken on its own, grounding an electric motor looks simple: the frame is connected to earth and safety is ensured. But once the motor is driven by a variable frequency drive (VFD),... More Details

In underground mines and long tunnels, ventilation is the foundation not of production but of life safety. The main ventilation fans that force fresh air into the mine or extract f... More Details

One of the most common and most critical checks when commissioning an IE3 efficient asynchronous motor in the field is the direction of rotation. A motor can be correctly wired, ha... More Details

kW tells you “how powerful” an electric motor is; but torque (moment, Nm) tells you how forcefully that motor can turn the machine. What will lift the load — or f... More Details

You bought an efficient motor — but was the efficiency on the nameplate actually achieved in the field? For facilities that want to put measured real savings into a savings r... More Details

However safely an IE4 motor runs at a sea-level plant, running that same motor at the same power at a mine or highland facility at 1500 metres may not always be possible. The reaso... More Details

Even when a cast iron electric motor looks rugged on the outside, the part that actually transmits torque to the machine is the shaft. The shaft is the lifeline that carries the mo... More Details

IE5 synchronous reluctance (SynRM) motors stand out not only for their ultra-premium efficiency class but also for the dynamic torque behaviour they gain through drive control. In ... More Details
