Some industrial environments carry a risk of explosion because of the flammable gas, vapour or dust they contain. Petrochemical plants, refineries, paint factories, flour and sugar... More Details

From furniture to construction, from joinery to packaging, wood is processed with a wide range of machines. Saws, planers, milling and sanding machines, CNC routers; all of them ru... More Details

When an electric motor is switched on directly, it draws a current far above its normal running level and a sudden mechanical jolt occurs. This abrupt start strains the motor, the ... More Details

One of the most frequent threats an electric motor faces is overload. When a motor runs above its capacity, it draws excessive current, heats up and over time can burn out. Overloa... More Details

There is more than one way to connect an electric motor to the equipment it drives, and this is called the mounting type. Foot, flange or combined mounting options determine how th... More Details

Electric motors cannot convert all of the energy they draw from the network into useful work; a portion is used to create the magnetic field and never turns into work. The concept ... More Details

When replacing an electric motor or connecting one to a piece of equipment, one of the most frequently encountered concepts is the frame size. Defined according to the IEC standard... More Details

The most heavily worn and most frequently failing component of an electric motor is its bearings. A significant share of motor faults stems directly from bearing problems. Well-mai... More Details

Heavy industry, ranging from mining and cement to iron-steel works and stone-crushing plants, is the arena where electric motors operate under the most demanding conditions imagina... More Details

Most electric motors are designed to run at a single fixed speed. Some applications, however, require the motor to operate at two different speeds. One of the solutions that answer... More Details

Some applications require a motor to run at two different speeds. One of the common ways to obtain two speeds from a single motor is the Dahlander connection. This method provides ... More Details

Most electric motors treat vibration as an unwanted problem and try to keep it to a minimum. In some applications, however, vibration is exactly what is wanted. Vibration motors ma... More Details

Steel and foundry plants are among the harshest and highest-temperature environments in all of industry. Molten metal, intense heat, heavy loads and constant production pressure st... More Details

Wherever an electric motor is going to operate, it must be protected against the dust, moisture and water of that environment. The level of this protection is defined by the IP pro... More Details

The most widely used motor in industry is the induction motor. However, in places that demand precise positioning, step and servo motors are preferred. These three motor types are ... More Details

Cooling towers are critical equipment used to cool water in industrial plants, power stations and large air-conditioning systems. The cooling function of these towers depends on th... More Details

How high a temperature an electric motor can withstand depends on the insulation of the windings inside it. The insulation class, shown on the motor nameplate with a letter such as... More Details

In industry, electric motors are often designed to run at a fixed speed. Yet in many applications, the motor does not always need to turn at full speed. This is where the frequency... More Details

Three-phase electric motors run on the balanced energy of three phases, and that balance is the foundation of healthy operation. But if one of the phases is cut off or lost for any... More Details

In the traditional approach to maintenance, repairs are either carried out after a breakdown occurs or planned maintenance is applied at fixed intervals. Both methods have their sh... More Details
