Mechanical Characteristics : The Siemens 1IGA 253-6AA90-Z 250M motor offers stable and reliable torque, designed to operate continuously (duty S1) with high performance. It is particularly suitable for applications where long-term operation and resistance to adverse conditions are required.

Usage Procedure : The motor is connected directly to the three-phase network with the specified configuration (400 VD/690 VY at 50 Hz or 460 VD at 60 Hz). It is ideal for industrial machinery such as pumps, fans, compressors and conveyors. The installation must be carried out respecting the IM B3 assembly specifications or other variants to ensure stability and correct distribution of mechanical forces.

Matching Accessories : Can be paired with gearboxes, speed control systems (VFD), and feedback sensors to monitor operation. It is compatible with multiple accessories to optimize system efficiency.

Mathematical Formulas for Sizing : To calculate the optimal load and ensure correct use of the motor:

• Absorbed Power (P) : P=3×V×I×cos⁡ϕηP = \frac{\sqrt{3} \times V \times I \times \cos\phi}{\eta} $P$ $=$ η 3 ​× V × I × c o s ϕ
• Torque (T) : T=P×9550NT = \frac{P \times 9550}{N} $T$ $=$ N P × 9550 ​, NN $N$ is the speed in revolutions per minute (rpm).

Maintenance : To keep the engine in good condition, it is important to periodically check the bearings, lubricate them adequately and check the integrity of the cooling system. Routine maintenance reduces the risk of unexpected breakdowns.

Sectors of Use : The Siemens 1IGA 253-6AA90-Z 250M is used in many industrial sectors, including manufacturing, petrochemical, and industrial automation, thanks to its reliability and robustness.

Advantages of Purchasing Used : Purchasing this used Siemens motor can offer significant advantages in terms of costs and immediate availability. Being a robust and durable product, a used engine can maintain its performance over time if properly maintained, making the investment worthwhile for applications where reliability is essential
