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

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

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

The correct operation of an electric motor depends on its power, speed and efficiency, and on how it is mounted. The way the motor connects to the machine, that is the mounting typ... 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

The small metal plate on an electric motor is, in effect, that motor's identity card. Among the codes printed on this nameplate, perhaps the most asked about and the most critical ... More Details

Power plants, although they are facilities that generate electricity, also consume a large amount of electricity internally. Most of this consumption comes from the electric motors... More Details

Induction motors are divided, by rotor construction, into two broad families: the squirrel cage (short-circuited bar) rotor and the wound rotor (slip-ring) motor. From the outside ... More Details

Aggregate and quarry plants are among the most demanding operating environments for electric motors. In these plants, where tonnes of rock are crushed, screens vibrate constantly a... More Details

Induction motors are the most widely used sources of motion in industry, and at the heart of how these motors work lies the concept of slip. An induction motor can only produce tor... More Details

When selecting an electric motor, the first value most people look at is the power rating in kilowatts. Yet the concept that truly determines how a motor will behave in real life, ... More Details

There are two basic ways to turn a machine or a pump: either set up a mechanical drive with a diesel generator or engine, or use an electric motor fed from the grid. This choice di... More Details

The foundation of running an electric motor safely and efficiently lies in a properly built motor panel. At the heart of this panel is the contactor, which switches the motor in an... More Details

In industrial facilities, warehouses, and large commercial buildings, the quality of the indoor air directly affects production efficiency and worker health. One of the most effect... More Details

The heart of an electric motor is the windings placed inside its stator. These windings directly determine the motor's power, efficiency, and service life, and they are formed thro... More Details

Ceramic production involves many stages, including raw material preparation, forming, drying, firing, and glazing. Electric motors are at work in nearly all of these stages. A wide... More Details

Overhead cranes are industrial lifting systems that move heavy loads both horizontally and vertically. In these cranes, travel motors drive the movement of the bridge and the troll... 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
