SINAMICS is Siemens' brand of inverter (Siemens being a leading manufacturer in electric drive technology). With SINAMICS frequency conversion technology, you can utilize it for various applications - low voltage, medium voltage, or DC. It can be used to control both synchronous motors and induction motors, depending on the machine's characteristics.
The frequency converter (also known as Inverter or VFD)by Siemens integrates safety technology and can be used in centralized systems and operated within control cabinets, wall-mounted installations, or used in distributed systems. Siemens provides energy-efficient and optimized frequency converter units for each application (such as pumps, ventilation systems, motion control, position control, or machining machines, etc.).
