Output voltages are configurable as per design to suit specific requirements. Available in standard or customized sizes, they handle varied current ratings and support operation in temperatures from -10C to 45C, making them suitable across diverse locations in India and beyond.
FAQs of Motor Generator Sets:
Q: How does a motor generator set convert electrical energy to a different voltage or current form?
A: The motor generator set uses an electric motor coupled to a generator. The motor receives input power (typically 415 V, three-phase) and drives the generator, which outputs electrical energy in the desired voltage and current form (commonly 110 V, 220 V, or 415 V), allowing for voltage and frequency conversion as needed.
Q: What benefits do vibration dampers and a sheet metal enclosure provide?
A: Vibration dampers isolating the set reduce operational noise and equipment wear, while the powder-coated sheet metal enclosure protects the device from dust, moisture, and impact. Together, they ensure quiet, reliable operation and extend the units service life.
Q: When should I consider using a motor generator set for my facility?
A: A motor generator set is ideal when you need reliable voltage conversion, electrical isolation, or frequency transformation for sensitive or critical equipment. They are commonly used in industrial settings, laboratories, or as power backup where equipment must operate efficiently under varied electrical conditions.
Q: Where can this motor generator set be installed, and what are the mounting options?
A: These sets are designed for installation in indoor industrial or laboratory environments and are base frame mounted. Vibration dampers come pre-installed to ensure stability. They can be placed wherever a robust, stationary voltage conversion solution is needed.
Q: What process is involved in monitoring and controlling the motor generator set?
A: Operators use the integrated control panel, which features MCCB protection, analog and digital meters, and indicator lights. Terminal block connections and inbuilt voltage, current, and temperature sensors allow for continuous monitoring and safe operation, reducing the risk of overload or malfunction.
Q: How does the air-cooled, self-lubricated bearing system impact maintenance?
A: The air-cooled design and self-lubricated bearings mean the unit requires less maintenance compared to water-cooled or externally lubricated systems. These features ensure the motor generator set operates efficiently with minimal attention, maximizing uptime.
Q: What is the primary usage and benefit of a motor generator set in industrial applications?
A: Primarily, these sets facilitate voltage and frequency conversion or electrical isolation, protecting equipment and ensuring compatibility with different power systems. Their robust construction, high efficiency, and built-in safety features provide reliable, long-term benefits for various industrial, laboratory, and power backup applications.
