3000 rpm electric motor for energy-intensive production lines
In heavy manufacturing plants, pumping stations and technological systems, a drive is expected to provide stable operation, reasonable losses and a reliable response to load. The H17RL 355X2-2 from VYBO Electric is designed for situations where energy efficiency affects operating costs every day and where a 3000 rpm electric motor must deliver power without taking up unnecessary extra space.
At 400 kW and high speed, the mechanical integrity of the assembly is equally important. The heavy-duty design with a cast-iron frame helps keep vibrations under control while supporting long-term operating stability in environments with variable loads. In practice, this is appreciated by operators of large factories as well as OEM manufacturers of technological systems that need to connect the drive directly to an existing production line.
Compact output in a frame that saves machine space
The main advantage of this solution is its compact output relative to the space required for installation in the machine. Thanks to the 355 mm frame size, it is easier to work with the design of the base, guarding and service access, which is important both when modernizing older plants and when designing new production lines. An electric motor with this power density helps reduce layout space requirements without compromising the operating mode.
The rated torque of 1283 Nm, together with suitable starting characteristics, supports smooth acceleration of assemblies with higher inertia. This is beneficial, for example, in conveyors, mixers and driven process units where repeated starts under load are expected. An asynchronous electric motor of this class therefore fits better into drives where not only output but also the continuous load on the electrical network is monitored.
Cast-iron construction for long-term operating stability
The robust cast-iron construction provides high mechanical resistance during handling, installation and long-term operation. In industry, this type of solution proves effective wherever vibration, dust, temperature fluctuations and continuous operation are present. This design supports the service life of the assembly and helps maintain precise alignment even over long operating cycles.
Insulation class F together with temperature rise B provides an operating margin suitable for more demanding applications with higher loads. With an efficiency of 96,1 %, the energy supplied to the drive is used more effectively, while the 0,89 power factor helps when designing the electrical part of the drive system. This is important in facilities where not only immediate output but also overall operating costs are monitored.
Advanced lubrication and maintenance for fewer shutdowns
The motor is equipped with bearing relubrication during operation, which makes it easier to plan service interventions and reduces the need for unnecessary shutdowns. DE 6220C3 and NDE 6220C3 bearings are suitable for stable industrial operation where every hour of downtime matters. In practice, this means better control over servicing and a more predictable maintenance interval.
When operating with an external starting inertia of 131,000 kg·m² and a GD² moment of inertia of 14,000 kg·m², it is important that the drive can handle the load profile without unnecessary interruptions. This is particularly valuable for operators of equipment running continuously and requiring precise scheduling of shutdowns around production windows.
Suitable for heavily loaded technological systems
The H17RL 355X2-2 can be used for belt conveyors, rolling lines, high-flow fans, compressor stations, crushers, mixing units, cooling-circuit pumps, extrusion lines, granulation equipment, milling centres, winding machines, rotary drum dryers, dust separators, hydraulic power units, bridge-mounted technological systems and drives for large transport mechanisms.
VYBO Electric for industry that needs dependable operational support
Years of experience at VYBO Electric can be seen in how this electric motor is prepared for long-term deployment in demanding conditions. The combination of 400/690 V, 677 A at △ 400 V and 393 A at Y 690 V gives designers flexibility to size the power supply correctly according to the specific switchboard and network type. H17RL Compact PRO therefore fits projects where technical continuity and predictable servicing are decisive.
Starting characteristics for heavy starts and inertial loads
A starting torque of 140 % and a breakdown torque of 200 % help when starting assemblies with higher mechanical loads. The 700 % starting current must be taken into account when designing protective and switching components, especially in projects with multiple drives on one supply branch. At a rated speed of 2978 rpm, operation remains suitable for applications requiring smooth running close to synchronous speed.
The weight of 2300 kg reflects the robust construction intended for fixed industrial installation. Combined with the high power density, this solution helps maximize the use of space both in the machine room and within the technological block. For large factories and OEM integrators, it provides a practical foundation for a drive designed to operate for the long term without constant fine-tuning.
