In heavy production lines, mills and compressor stations, the drive must withstand long-term loads without fluctuations in output. The 700 rpm electric motor H17R 400-D-8-6 with an output of 450 kW is designed precisely for such applications, combining compact power with reserve capacity for demanding process modes. For operators of large factories as well as OEM integrators, this means a solution that can be reliably incorporated into technological systems with high requirements for availability.
700 rpm electric motor for continuous industrial loads
When used in heavy-duty drives, it proves itself as a three-phase electric motor that helps maintain stable operation during long operating cycles. In practice, you will also appreciate the characteristics of a high-voltage electric motor when larger technological systems need to be powered with an emphasis on low system losses. The design is suitable for HV electric motors integrated into production lines with high requirements for continuity and predictable servicing.
Copper rotor as the basis for a long service life
Copper strip in the rotor cage improves energy transfer during starting as well as steady-state operation. Low losses result in lower thermal stress and a longer service life of the insulation and mechanical components. For plants with continuous production, this is an important difference because the motor better withstands repeated starts, load changes and long running periods without unnecessary overheating.
- Copper rotor for long service life supports reliable operation in modes with frequent duty cycles.
- Lower rotor losses contribute to reduced heating under long-term load.
- High thermal resistance helps maintain stable operation in demanding industrial environments.
Efficiency that helps reduce operating costs
IE4 Super Premium efficiency is beneficial where the motor operates for dozens of hours a day and every watt saved is reflected in the costs of the entire plant. For OEM manufacturers of large technological systems, it is important that higher efficiency facilitates drive design with a better energy balance. Over the long term, this improves the economy of the technology without requiring compromises in robustness.
- IE4 Super Premium efficiency supports energy-efficient operation in demanding drives.
- Stable efficiency helps optimize consumption in continuous production.
- Lower operating losses improve the economics of the entire drive over its life cycle.
Voltage selection for easier integration into the power network
The option to select the voltage facilitates project design in plants with different network architectures and requirements for a standardized machine fleet. Availability of 3 300 V, 6 000 V, 10 000 V and 11 000 V levels simplifies design for modernization projects as well as the construction of new facilities. The 400 mm frame size also supports mechanical stability when installed in larger technological frames.
In this environment, precise sizing as an 8-pole electric motor also proves its value, making it suitable for applications with medium speeds and high torque. A weight of 4310 kg and rotor moment of inertia of 16,0 kg·m² give the design the required stability during starting and load changes. Rated torque of 5807 Nm provides reserve capacity for processes that require smooth power transmission without sudden fluctuations.
Applications in heavy production and technological systems
This 700 rpm electric motor is used in cement mills, bulk-material conveyor stations, pump units for the energy industry, compressor blocks, mixing equipment for the chemical industry, extruders for polymer processing, rolling lines in metallurgy and fans for extraction systems in large halls. In each of these applications, stable operation is important, supported by rated speed of 740 rpm, rated current of 56,3 A and power factor of 0,81. For machine designers, this is a practical basis for reliable drive design with long service intervals.
Temperature management is prepared for industrial use thanks to insulation class F and temperature rise B, which helps under long-term load and fluctuating ambient temperatures. 6326-C3 bearings on both the DE and NDE sides support smooth operation in applications where precise mounting and long-term mechanical durability are required. Accessories are also available in the form of 6 x PT100 in the winding, 1 x PT100 in the NDE bearing, 1 x PT100 in the DE bearing, an anti-condensation heater and 3 x PTC thermistor, which facilitates monitoring of the motor condition in sensitive applications. VYBO Electric is the largest company in its sector in Central Europe, which is why this motor is a natural choice for projects that need to combine performance, reliability and long service life; take advantage of the offer and bring your drive to a level that reduces the risk of unplanned downtime.
