Choosing the right electric motor is not enough on its own; the cable that feeds that motor must also be chosen correctly. A wrongly chosen supply cable becomes the weak link of th... More Details

There is only one sound way to understand whether switching to an efficient motor makes sense: do the math. The sentence "a high-efficiency motor saves energy" is true but abstract... More Details

Whenever an electric motor burns out in an industrial setting, the same question arises: should we rewind this motor or buy a new one? Rewinding is the process of stripping out the... More Details

How quickly a motor can bring a load to the desired speed depends on a critical quantity that is often overlooked yet determines both the starting behavior and the life of the moto... 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

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

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

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

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

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

One of the most fundamental decisions when selecting a motor to drive a machine is this: should the motor be connected directly, or should a gearbox be placed in between? This choi... More Details

Whether an electric motor is mounted horizontally or vertically may at first look like nothing more than a layout preference. In reality, this choice directly affects many mechanic... More Details

When you run an electric motor for years, you come to know its behavior intuitively: which sound is normal, what temperature to expect, how it responds under a given load. The conc... More Details

When an electricity bill comes in higher than expected, the first remedy that comes to mind is usually to swap a single component, the motor, for a more efficient model. Yet an ele... More Details

When an electric motor fails or its efficiency drops, the first question that usually comes to mind is "should I buy a new one?" Yet a motor's life does not end with its first faul... More Details

For many years, industry produced heat by burning fuel. Today this equation is changing: industrial heat pumps take low-temperature waste heat and lift it to the higher temperature... More Details
