Efficient electric motors in the low-kW range are designed for applications that need small power but where efficiency still matters. Even at low power, a high efficiency class pro... More Details

IE3 and IE4 electric motors are two classes that represent the highest levels in energy efficiency. Both run with low losses; the difference between them is the efficiency level an... 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

IE3, IE4 and IE5 electric motors represent the three highest efficiency classes in the IEC 60034-30-1 standard. The main difference between them is the level of energy loss while d... More Details

An electric motor price list shows how motors are priced by power, speed, efficiency class and housing type. To compare IE3, IE4 and IE5 motors correctly, it is important to know h... More Details

IE3 electric motors run in the Premium efficiency class and have become standard in many areas of industry. They are the most preferred class in continuously running applications w... More Details

Electric motor prices are often not the fixed list figure people assume. Price is set by the motor's technical features, efficiency class and housing type. To see the right price, ... More Details

When selecting an electric motor, the choice between an aluminum housing and a cast iron housing is made by the application's load, the need for portability and the operating envir... More Details

Single-phase induction electric motors run on a single-phase supply and are widely used in low-power applications. They are a practical, economical solution for workshops, small bu... More Details

Asynchronous motors are the most widely used motor type in industry thanks to their simple construction, durability and low maintenance. Being available across a wide power range m... More Details

Industrial (general-purpose) electric motors are the basic power source of production and businesses. Their prices are set not by a single list figure but by a combination of techn... More Details

How Low-Loss Electrical Steel Laminations Improve Motor Efficiency When we list the factors that determine an electric motor's efficiency, the first things that usually come to min... 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

Diagnosing Broken Rotor Bars with Motor Current Signature Analysis (MCSA) One of the most critical yet hardest-to-reach parts of an asynchronous motor is its rotor. The rotor forms... More Details

At the heart of a data center sit the servers, but the infrastructure that keeps those servers running without interruption is the cooling system. If the heat produced by thousands... More Details

dv/dt and Reflected-Wave Overvoltage on Long Motor Cables The cable between a frequency inverter (VFD) and an asynchronous motor is a component that is often overlooked, yet it is ... More Details

When buying an electric motor, many businesses reach for a slightly larger frame "just to be safe." On the surface this feels prudent, but it quietly turns into a trap that drains ... More Details

Shaft Voltage and Bearing Currents in VFD-Driven Motors Driving an asynchronous motor with a frequency inverter (VFD) brings major advantages in energy savings and flexible speed c... More Details

The correct operation of an electric motor depends not only on its power, speed and efficiency, but also on how it is mounted. The way the motor connects to the machine, that is th... More Details

When you look at the nameplate of an electric motor, you see that the power is sometimes written in kilowatts (kW) and sometimes in horsepower (HP). The speed is given as revolutio... More Details
