H17RL 450X1-6 for energy-efficient industrial drives

The H17RL 450X1-6 motor is designed for operations where energy efficiency, stable starting and long-term reliability under high load are decisive. This 900 rpm electric motor belongs to the VYBO Electric portfolio and is suitable in practice for operators of production halls and OEM manufacturers of large technological systems who need a precisely sized drive for continuous operation.

900 rpm electric motor for smooth operation of production systems

Rated speed of 990 rpm provides balanced operation for applications where a combination of strong engagement and stable running is important. The low-voltage electric motor in this design is suitable for a 400/690 V supply and can be integrated into systems with direct starting or controlled acceleration according to the requirements of the technology.

• An output of 630 kW supports equipment operating under continuous load.
• Rated torque of 6077 Nm provides reserve capacity during operating peaks.
• A starting torque ratio of 110 % helps when starting loaded assemblies.
• A breakdown torque ratio of 200 % increases stability during short-term load fluctuations.

In practice, this is an electric motor that performs well in uninterrupted technological lines and drives requiring controlled energy transfer into the mechanical system.

Robust cast-iron construction for heavy industrial operation

Robust cast-iron construction helps maintain dimensional stability, limits the effect of vibration and improves resistance to long-term mechanical stress. This solution is particularly important where the motor operates in combination with gearboxes, pumps or special technologies with high requirements for mounting accuracy.

• A weight of 4800 kg contributes to stability in fixed installation.
• Insulation class F supports safe operation under higher thermal load.
• Temperature rise B helps maintain a favourable winding temperature regime.
• The rotor cage made of copper bars is intended for demanding starting and operating cycles.

For operations with long service intervals, the bearing section is also important, which is why VYBO Electric uses DE bearing 6328C3 and NDE bearing 6328C3 for consistent mechanical support of the rotor.

Compact output in a 450 mm frame for OEM solutions

Compact output is particularly important in this design for OEM projects where high performance must be combined with limited installation space. The 450 mm frame size enables efficient integration of the drive into larger assemblies without unnecessarily increasing the size of the complete machine.

• A 450 mm frame size simplifies integration into industrial units.
• Rated current △ 400V 1104 A supports power-supply sizing.
• Rated current Y 690V 640 A allows different connection methods.
• A GD² moment of inertia of 64,000 kg·m² helps when designing starting modes.

External starting inertia of 620,000 kg·m² is an important value for designers dealing with the starting of large units, transport systems or technological assemblies with high inertia.

Choice of efficiency class when planning consumption

For long-term operation, the option to choose the efficiency class is also an advantage because it allows the motor to be adapted to the specific load profile and technology objectives. This flexibility is useful both when designing new production lines and when modernising older drives where return on investment is assessed through operating costs.

• Efficiency of 96,1 % supports more economical operation under normal load.
• A power factor of 0,86 helps with the design of the supply and compensation section of the system.
• Availability of multiple classes allows the motor to be incorporated into the company’s energy concepts.

Within the VYBO Electric portfolio, this low-voltage electric motor is used in cement production lines, rolling lines, mixing centres, crushing lines, ore conveyors, vertical mills, ball mills, boiler-room fans, compressor stations, water pumping stations, drainage pumps, extrusion lines, paper-machine drums, wood-chip crushers and feed-mill drives. These applications require precisely matched torque characteristics, reliable bearings and construction capable of handling long operating intervals without unnecessary downtime.

Thousands of satisfied VYBO Electric customers confirm that a motor sized this way can perform over the long term under demanding operating conditions. Order the H17RL 450X1-6 in good time, because availability and delivery speed are decisive in high-output projects with fixed installation dates.
