 <\/p>\n

In this video, we discover the DE840<\/strong>, a single-phase motor with an integrated inverter, and explain why it’s an ideal solution for rotary pumps<\/strong> in demanding industrial applications<\/strong>. You’ll learn about its technical specifications, control capabilities, and real-world use cases.<\/p>\n

 <\/p>\n

Why Inverter Motors matter for industrial applications<\/strong><\/p>\n

Modern industrial applications<\/strong> 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<\/strong> solves this issue by integrating both components into a single compact unit, purpose-built for advanced control of rotary pumps<\/strong>.<\/p>\n

This is key in facilities where panel space is limited, or where fluid handling<\/strong> and dosing systems<\/strong> require precise, adjustable performance without added wiring complexity.<\/p>\n

 <\/p>\n

Technical specifications that deliver performance<\/strong><\/p>\n

The DE840<\/strong> is available in a 0.75 kW<\/strong> 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 \u2014 a critical factor for rotary pump<\/strong> performance in industrial applications<\/strong>.<\/p>\n

Thanks to V\/F control technology with Space Vector modulation, the DE840<\/strong> achieves efficiency above 90%<\/strong>, smooth operation, and a continuous overload capacity up to 150%<\/strong>. Designed for S1 continuous duty<\/strong>, with IP65 protection<\/strong> and an integrated Class A \/ Category C1 EMC filter, it’s built to perform reliably even in harsh industrial environments.<\/p>\n

 <\/p>\n

Complete signal management and automation integration<\/strong><\/p>\n

One of the standout features of this inverter motor<\/strong> 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<\/strong>, and RS485 serial communication with ModBus RTU protocol.<\/p>\n

This level of connectivity allows seamless<\/strong> integration with encoders, PLCs, and supervision systems<\/strong>, making the DE840<\/strong> highly versatile for industrial automation. Available configurations include remote start\/stop<\/strong>, direction reversal<\/strong>, multispeed<\/strong>, motor-potentiometer<\/strong>, and analog\/digital signal management<\/strong> \u2014 giving + full flexibility to match the motor<\/strong> to their process needs.<\/p>\n

 <\/p>\n

Direct pump coupling and real-world applications<\/strong><\/p>\n

Compact, robust, and easy to install, the DE840<\/strong> is engineered for direct coupling with RO1000 rotary pumps<\/strong>, supporting flow rates of up to 1400 liters per hour<\/strong>. This makes it particularly suited for industrial plants<\/strong>, dosing systems<\/strong>, fluid handling<\/strong>, commercial installations<\/strong>, and process automation<\/strong>.<\/p>\n

Whether you’re upgrading an existing pump system or designing a new installation, the DE840<\/strong> offers a plug-and-play path to smarter, more efficient industrial applications<\/strong>.<\/p>\n

 <\/p>\n

The DE840 inverter motor<\/strong> combines smart control, maximum integration, and professional performance in a single compact solution. For those seeking reliable, flexible motor for rotary pumps<\/strong>, it represents an ideal solution toward smarter, more efficient operations.<\/p>\n

 <\/p>\n

FAQ<\/strong><\/p>\n

 <\/p>\n

What is an inverter motor, and how is the DE840 different from a standard setup?<\/strong><\/p>\n

A motor with an integrated inverter incorporates variable frequency control directly into the motor assembly. The DE840<\/strong> 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.<\/p>\n

 <\/p>\n

What flow rate can the DE840 support when paired with a rotary pump?<\/strong>
\nWhen directly coupled to an RO1000 rotary pump, the DE840<\/strong> supports flow rates of up to 1400 liters per hour.<\/p>\n

 <\/p>\n

Can the DE840 be integrated into existing automation systems?<\/strong>
\nYes. Through RS485 ModBus RTU<\/strong> communication, analog\/digital inputs, and HSI inputs<\/strong>, the DE840<\/strong> integrates smoothly with PLCs<\/strong>, encoders, and supervision systems.<\/p>\n
