Electric motor 900 kW, 2985 rpm, 400/690 V, H17RL 450X2-2

In heavy industrial operation, it matters whether the drive can handle long shifts without unnecessary downtime and whether it fits into the limited space of the technological system. The H17RL 450X2-2 from VYBO Electric is a 2900 rpm electric motor that combines high power density with a solution for equipment where every centimetre of installation space and every production cycle matters. For factory operators and OEM integrators, it is important that this electric motor delivers 900 kW in dimensions that simplify the design of units, pumping stations, compressor rooms and heavy technological lines.

Compact output for drive units with high loads

When designing drives for mills, conveyors or fan blocks, compact output is often decisive. This asynchronous electric motor operates at 2985 rpm, giving designers scope for direct connection to high-speed applications and reducing the need for complex transmission stages. Rated torque of 2879 Nm supports stable starting even when the load is not ideally distributed throughout the production cycle.

In practice, this means easier integration into drive technology, shorter design time and fewer compromises when installing the motor in machine frames. With rated current of 1640 A at △ 400V and 883 A at Y 690V, the motor can be adapted to the voltage arrangement of the electrical network without unnecessary changes to the drive concept. Efficiency of 96,1 % supports efficient long-term operation, which is particularly important in large production systems running continuously.

H17RL 450X2-2 where every installation detail matters

The 450 mm frame size helps in projects where the motor is expected to provide high output without unnecessarily increasing the dimensions of the enclosed unit. Robust cast-iron construction improves mechanical resistance and helps maintain stability under vibrations generated in demanding technological assemblies. For large factories, this is a practical benefit because the rigid motor frame limits deformation under long-term load and supports long bearing life as well as stable mounting of the complete drive.

DE 6221C3 and NDE 6221C3 bearings are equally important and are selected with regard to operation requiring high running accuracy. A GD² moment of inertia of 24,800 kg·m² together with external starting inertia of 294,000 kg·m² gives designers the data needed to design the start and assess assembly dynamics. With these values, the motor is ready for applications where not only output but also the behaviour of the complete system during load changes must be considered.

Voltage according to network and operating standard

The option to choose the voltage is a practical tool in large industrial projects, not merely an additional item in the documentation. This solution makes it possible to adapt the electric motor to the available infrastructure while preserving reserve capacity for the specific requirements of a particular machine. For OEM integrators, this means less pressure to modify switchboards and easier coordination with existing plant standards.

Operators appreciate that the available voltage variants of 440 V, 500 V, 690 V and 720 V make deployment easier in international projects where different voltage systems are used within one equipment group. From a maintenance perspective, it is also advantageous that a common design shortens the time needed for replacement planning and simplifies service logistics.

Starting that can handle demanding technology

A starting torque ratio of 110 % and a breakdown torque ratio of 200 % help in applications where the motor encounters higher resisting loads from the first seconds of starting. A starting current ratio of 750 % must be taken into account in the design, but with correctly designed distribution and protection it is a parameter routinely considered in heavy-duty practice. Temperature rise B and insulation class F support safe operation over longer operating intervals and in thermally demanding environments.

These characteristics are appreciated by those designing drives for equipment with repeated starts or fluctuating loads. Combined with high efficiency and a power factor of 0,89, this is a solution that fits operations focused on stability, reliable starting and control of energy costs. VYBO Electric builds on manufacturing and inspection processes where ISO certificates form part of the established quality system, which is an important factor in large industrial purchases.

Industrial applications for continuous production

This 2900 rpm electric motor can be used in the following applications:

• Main drive of a cement mill in a building-materials plant.
• Drive of an axial fan in an industrial-waste incineration plant.
• Drive motor for an extraction compressor in a chemical operation.
• Drive unit for a process-water pumping station.
• Drive of a rolling line in metallurgical production.
• Motor for a crusher in mineral processing.
• Drive of a mixer in a paper-mill suspension system.
• Drive motor for an extruder in plastic-granule production.
• Drive of a belt conveyor in a bulk-material terminal.
• Motor for a centrifugal pump in an energy unit.

Operation focused on maintenance and long service intervals

A weight of 5300 kg is a normal consequence of the robust construction in this type of drive, supporting rigid mounting and vibration damping. For plant maintenance personnel, this is especially important when the motor is installed in an assembly with limited access or in a frame that must transmit large dynamic forces. A correctly designed service plan can then take advantage of the mounting stability and precisely selected bearing configuration.

In practice, this electric motor is worthwhile where continuous operation, long production runs and pressure to minimise downtime are expected. This makes it easier to maintain the rhythm of the complete line and reduces the risk of unplanned shutdown of the technological system. If you need a motor for a large production project, contact us.
