The codes you see on an electric motor's nameplate, such as IP55 or IK08, represent two separate languages that describe how durable the motor is against the outside world. The IP ... More Details

When an electric motor is fed from the mains, the high current it draws at the moment of starting often goes unnoticed, because the city grid behaves like an almost unlimited sourc... More Details

Working underground is one of the toughest assignments an electric motor can face. Mines and tunnels are environments where the accumulation of explosive gas and dust, high humidit... More Details

The efficiency value printed on an electric motor's nameplate is a design target achieved under ideal conditions. If you want to learn how efficiently that motor actually runs in t... More Details

The majority of failures that take an electric motor out of service start not in the windings or the control board, but in its mechanical heart: the bearings. A bearing is the part... More Details

Equipment operating at sea faces a far harsher world than its land-based counterpart. Constant salt spray, high relative humidity, the changing inclination angles caused by the shi... More Details

An electric motor runs healthily only if the energy feeding it is as sound as the motor itself. Under ideal conditions, the voltage coming from the grid should have a constant ampl... More Details

Oil and gas facilities are industrial environments where electric motors must operate to the highest standards of reliability and safety. In the processes of refining, pumping, and... More Details

The rotation direction of an electric motor may look like a minor detail at first glance, but in many applications it is a critical matter that determines whether the job can be do... More Details

Rolling mills and metal forming facilities are production environments where electric motors undergo some of their toughest tests. The process of crushing hot metal between rolls t... More Details

The lifespan of an electric motor largely depends on choosing the right electrical equipment to power and protect it. No matter how high the quality of the motor itself, if a suita... More Details

Wastewater treatment plants are industrial facilities that play a critical role in protecting environmental health and must run without interruption around the clock. The process o... More Details

Cement manufacturing represents one of the harshest operating environments in heavy industry. From crushing raw materials to firing clinker, from grinding to packing, hundreds of i... More Details

Escalators and moving walkways carry millions of people every day, from shopping malls and metro stations to airports and business centers, and they are expected to run without int... More Details

Every mechanical structure has a frequency at which it vibrates most easily when slightly disturbed; this is called the natural frequency. The sound you hear when you tap a glass w... More Details

An electric motor cannot convert all the electricity it draws into mechanical power; some of it is inevitably turned into heat. For a single motor this heat may seem small, but in ... More Details

Brake electric motors are indispensable in applications that must stop quickly and safely the moment stopping is required. Cranes, elevators, conveyors, door systems, and machines ... More Details

An electric motor produces a certain amount of vibration while running; this is unavoidable. However, the severity of the vibration says a great deal about the motor's health. Low ... More Details

The only reliable way to understand how efficiently an electric motor truly runs is to measure it. The efficiency value printed on the nameplate is a reference obtained by the manu... More Details

The power and efficiency values printed on an electric motor's nameplate do not, on their own, tell you how the motor will behave in the real world. A motor heats up while running ... More Details
