Electric Motor Supply to Izmir ITOB OSB and Menderes-Tekeli Industry
In the south of Izmir, within the Menderes district, the ITOB OSB (Izmir Textile and Apparel Organized Industrial Zone) and the surrounding Menderes-Tekeli industrial basin form a ... More Details
Rated Torque and Torque Density in IE5 Synchronous Reluctance Motors: More Torque in the Same Frame?
When buying an electric motor, most plants look at power (kW) first; yet what actually turns the machine is not power but torque (rated torque, Nm). Two motors with the same kW rat... More Details
Asynchronous Motor Starting Time and Moment of Inertia (J): Starting High-Inertia Loads Without Overheating
When choosing an asynchronous motor to drive a high-inertia load, there is one parameter most purchasing decisions overlook: the load moment of inertia J (kgm²). A large fan impell... More Details
Reading the IE5 Synchronous Reluctance Motor Nameplate and Label for Correct Drive-Matched Ordering
The IE5 synchronous reluctance (SynRM) motor is the most common representative of the ultra-premium efficiency class in the field, and unlike a classic asynchronous motor it can ne... More Details
Asynchronous Motor Efficiency-Load Curve (% Load): How Efficiency Changes at Part Load and Right Sizing
The efficiency value (%) written on the nameplate of an asynchronous motor shows the best point reached at full load. But in real plants motors rarely run at full load; most of the... More Details
IE5 Synchronous Reluctance Motor Noise and Sound Level (dB): Quiet Operation Advantage and Right Selection
IE5 synchronous reluctance (SynRM) motors offer an advantage that is often overlooked alongside their ultra premium efficiency: noticeably quieter operation. In HVAC plants near ho... More Details
Asynchronous Motor Derating Under Voltage Unbalance: Power Reduction, Heating and Protection via NEMA Curve
The power stated on an asynchronous motor's nameplate assumes a balanced (symmetrical) three-phase supply. In a real grid, however, the voltages of the three phases are often not e... More Details
IE5 Synchronous Reluctance Motor Torque Response to Sudden Load Changes: Speed Stability and Drive Selection
IE5 synchronous reluctance (SynRM) motors stand out not only for their ultra-premium efficiency class but also for the dynamic torque behaviour they gain through drive control. In ... More Details
Asynchronous Motor Speed-Torque (M-n) Curve and Breakdown Torque: Selecting the Right Motor for the Load
The most reliable way to know whether an asynchronous motor can drive a load correctly is to read the motor's speed-torque (M-n) curve. This curve shows how much torque the motor p... More Details
IE5 Synchronous Reluctance Motor Drive DC Bus Voltage and Supply: Correct Input Voltage and Panel Selection
An IE5 synchronous reluctance (SynRM) motor delivers its ultra-premium efficiency only when driven by a correctly matched variable frequency drive (VFD); therefore the DC bus volta... More Details
