Samsun, the industrial heart of the Black Sea, brings together a wide production range from food to wood, from mining to shipbuilding and agricultural machinery. This diversity cre... More Details
For an OEM that mass-produces, a plant that continuously consumes motors, or a machine builder expecting planned shipments throughout the year, the biggest risk is not the motor it... More Details
When ordering an electric motor there is one parameter as critical as power, speed and efficiency class, and it often comes to mind last: the mounting type. The mounting code (IM c... More Details
Selecting an electric motor by looking only at its power (kW) and speed (rpm) is often a half decision. Because what really determines whether the motor can carry the load, whether... More Details
In boiler rooms, steam plants and central hot-water systems there is one component that is easy to overlook yet directly determines the continuity of the line: the condensate (retu... More Details
Star-delta starting is the most common and most economical method of reducing the starting current on asynchronous motors. The motor is first connected in star, keeping current and... More Details
When you look at a motor's nameplate, you easily read its power, speed, current and efficiency class; but especially on a motor built to the NEMA standard, the single letter next t... More Details
When you run an IE5 synchronous reluctance motor at very high speed continuously, for example on a turbo blower, a high-speed compressor or a test bench, the most stressed part is ... More Details
When commissioning an IE4 super premium efficiency motor in a dusty environment, most engineers focus on the efficiency class, winding quality and bearing life; but they rarely loo... More Details
When moving a large cast iron asynchronous motor from the factory to the field, one thing is often overlooked: throughout the long transport period when the motor is not running an... More Details
In a crusher (stone-crushing) plant, the main crusher motor is the heart of the entire line. When this motor stops, not only the crusher but the whole feeder, conveyor and screeni... More Details
On an IE3 motor running in high-power and critical applications, measuring winding and bearing temperature at only one point is not sufficient. Different regions of the motor heat... More Details
One of the most insidious faults of an asynchronous motor is an earth (frame) leakage. When the winding insulation degrades over time due to moisture, heat, vibration or contamina... More Details
When a machine needs to run at two different speeds, the first solution that comes to mind is a variable frequency drive (VFD). However, if only two fixed speeds are sufficient an... More Details
In pump, fan and blower applications, the most effective way to control flow, pressure and energy consumption is to adjust the motor speed precisely. In most cases a variable freq... More Details
High-efficiency electric motors stand out for their long life and low fault rate in continuously running pump, fan, compressor and process lines. But the most critical maintenance ... More Details
Most three-phase electric motors have a dual-voltage construction that allows them to run at two different voltages by re-arranging the bridges in the terminal box. A motor whose n... More Details
IE5 synchronous reluctance (SynRM) motors — with their magnet-free rotor, high efficiency and drive-coupled operation — represent the ultra premium efficiency class of the future. ... More Details
Large IE4 super premium motors running in continuous processes, pump-fan-compressor lines and critical production plants face the risk that a stator winding fault can destroy the e... More Details
Cast iron framed brake motors are used in conveyors, cranes, hoists and vertical drives where the load must be held safely. They are equipped with a spring-applied electromagnetic ... More Details
