In this video, we discover the DE840, a single-phase motor with an integrated inverter, and explain why it’s an ideal solution for rotary pumps in demanding industrial applications. You’ll learn about its technical specifications, control capabilities, and real-world use cases.
Why Inverter Motors matter for industrial applications
Modern industrial applications demand equipment that combines reliability, flexibility, and space-saving design. Traditional setups often require separate motors and inverters, adding complexity and installation time. The DE840 inverter motor solves this issue by integrating both components into a single compact unit, purpose-built for advanced control of rotary pumps.
This is key in facilities where panel space is limited, or where fluid handling and dosing systems require precise, adjustable performance without added wiring complexity.
Technical specifications that deliver performance
The DE840 is available in a 0.75 kW version, operating on single-phase 230V power at 50 or 60 Hz. It drives three-phase asynchronous motors with a variable output up to 160 Hz, ensuring precise control over both speed and torque — a critical factor for rotary pump performance in industrial applications.
Thanks to V/F control technology with Space Vector modulation, the DE840 achieves efficiency above 90%, smooth operation, and a continuous overload capacity up to 150%. Designed for S1 continuous duty, with IP65 protection and an integrated Class A / Category C1 EMC filter, it’s built to perform reliably even in harsh industrial environments.
Complete signal management and automation integration
One of the standout features of this inverter motor is its comprehensive I/O management. The DE840 offers 4 configurable digital inputs, 2 high-speed HSI inputs, an analog input compatible with 0-10V and 4-20mA signals, a programmable relay output, and RS485 serial communication with ModBus RTU protocol.
This level of connectivity allows seamless integration with encoders, PLCs, and supervision systems, making the DE840 highly versatile for industrial automation. Available configurations include remote start/stop, direction reversal, multispeed, motor-potentiometer, and analog/digital signal management — giving + full flexibility to match the motor to their process needs.
Direct pump coupling and real-world applications
Compact, robust, and easy to install, the DE840 is engineered for direct coupling with RO1000 rotary pumps, supporting flow rates of up to 1400 liters per hour. This makes it particularly suited for industrial plants, dosing systems, fluid handling, commercial installations, and process automation.
Whether you’re upgrading an existing pump system or designing a new installation, the DE840 offers a plug-and-play path to smarter, more efficient industrial applications.
The DE840 inverter motor combines smart control, maximum integration, and professional performance in a single compact solution. For those seeking reliable, flexible motor for rotary pumps, it represents an ideal solution toward smarter, more efficient operations.
FAQ
What is an inverter motor, and how is the DE840 different from a standard setup?
A motor with an integrated inverter incorporates variable frequency control directly into the motor assembly. The DE840 combines a single-phase powered inverter and a three-phase asynchronous motor in one compact unit. The integrated inverter converts the single-phase supply into a variable-frequency three-phase output, eliminating the need for a separate external inverter and simplifying installation.
What flow rate can the DE840 support when paired with a rotary pump?
When directly coupled to an RO1000 rotary pump, the DE840 supports flow rates of up to 1400 liters per hour.
Can the DE840 be integrated into existing automation systems?
Yes. Through RS485 ModBus RTU communication, analog/digital inputs, and HSI inputs, the DE840 integrates smoothly with PLCs, encoders, and supervision systems.
