An electric motor cannot convert all the energy it draws into mechanical work; part of that energy inevitably turns into heat. In most facilities, this heat is seen as a loss that ... More Details

There is a single graph that best describes the character of an induction motor: the torque-speed curve. This curve shows how much torque the motor can produce at every speed from ... More Details

Looking only at the price tag when buying an electric motor is like seeing only the visible tip of an iceberg. The economic reality of a motor reveals itself across the years you r... More Details

How much load an induction motor can carry, how long it will last and under which conditions it can operate safely are all tightly bound to a single physical phenomenon: the temper... More Details

No matter how high the power of an electric motor is, that power is useless if it cannot reach the shaft. The shaft is the bridge that transfers the rotary motion and torque the mo... More Details

When evaluating the noise of an electric motor, there are two concepts frequently encountered in catalogs and on nameplates: sound power and sound pressure. These two quantities, w... More Details

The life of an electric motor begins not the moment it is first started, but the moment it leaves the factory. Most facilities do not commission a motor immediately after purchasin... More Details

At the heart of choosing an electric motor correctly lies understanding the relationship between three quantities: power, torque and speed. These three concepts, which are often co... More Details

One of the greatest enemies of an electric motor is moisture, which is often invisible to the eye but advances silently. When moisture seeps inside the motor, it weakens the insula... More Details

When you change the speed of a motor in a pump or fan system, knowing in advance how much the flow, pressure and power will change is one of the fundamental questions of engineerin... More Details

The most critical mechanical component that determines the lifespan of an AC induction motor is the bearing, and the vast majority of these bearings are lubricated with grease. Gre... More Details

Induction motors draw not only active power from the grid to do useful work, but also reactive power to build up their magnetic field. This reactive power never turns into work at ... More Details

When the weight of a rotor turning thousands of times per minute is not evenly distributed at every point, a silent war begins inside even though the motor appears to run flawlessl... More Details

An electric motor is designed to run at the single voltage and frequency value written on its nameplate; however, in the real world the supply conditions never stay exactly fixed a... More Details

Two electric motors can have the same power, the same speed and the same efficiency; yet one runs flawlessly for years in a dusty crushing plant while the other burns its winding w... More Details

The moment an electric motor is first energized is one of the most demanding moments it experiences throughout its working life. A stationary asynchronous motor draws a current far... More Details

The most critical factor determining the life of an electric motor often comes down to a single, usually invisible variable: winding temperature. As long as the windings stay withi... More Details

Connecting an electric motor to the supply correctly is the first condition for safe and efficient operation. In three-phase asynchronous motors, this connection is made in the ter... More Details

At the heart of every electric motor lies an invisible yet critical boundary between the copper windings and the metal frame: the insulation. This layer, formed by enamel, varnish ... More Details

When an electric motor runs, it does not only produce mechanical power; it also releases heat in the windings, the rotor, and the bearing areas. If this heat is not kept under cont... More Details
