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

Operating 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. Installation must be performed in compliance with IM B3 assembly specifications or other variants to ensure stability and correct distribution of mechanical forces.

Compatible Accessories : Can be combined with gearboxes, variable frequency drives (VFDs), 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 engine:

• 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 your engine in good condition, it's important to periodically check the bearings, lubricate them properly, and check the integrity of the cooling system. Regular maintenance reduces the risk of unexpected breakdowns.

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

Advantages of Buying Used : Buying this used Siemens motor can offer significant advantages in terms of cost and immediate availability. Being a robust and durable product, a used motor can maintain its performance over time with proper maintenance, making the investment worthwhile for applications where reliability is essential.
