The 4-pole electric motor H17RL 450X1-4 brings compact output to drives where space, stability and long-term operation without unnecessary intervention are decisive. VYBO Electric designs this asynchronous electric motor for operators of large factories and OEM manufacturers who need a reliable source of torque for continuous technologies.
Robust cast-iron construction for continuous load
The cast-iron motor body increases the mechanical durability of the assembly and helps maintain precise mounting geometry even over long duty cycles. This robust construction is important where the drive is exposed to shock loading, vibration and thermally demanding environments.
- Drive of crushers in a stone-processing line.
- Main drive of a rolling line in a metallurgical operation.
- Compressor station for process air.
- Pump unit for circulation water in the energy sector.
- Drive of a conveyor system with high inertia.
- Mixer in a chemical production line.
- Dust-extraction fan in a cement plant.
- Extruder for polymer processing.
- Mill unit in raw-material processing.
- Winding stand for heavy strip materials.
- Main drive of a cellulose-processing line.
Energy efficiency during long production runs
Efficiency of 96,3 % and a power factor of 0,88 support energy-efficient operation at high utilisation, which is noticeable in the consumption balance of large plants. The asynchronous electric motor with a squirrel-cage rotor and copper rotor bars is designed to handle stable loads even during repeated starts.
Power-supply selection for different network conditions
A 400/690 V supply allows the motor to be adapted to standard industrial distribution systems as well as applications where the connection concept changes. The option to choose the frequency also opens the possibility of 60 Hz operation, which is practical for export assemblies and OEM projects intended for international use.
Rated torque of 5134 Nm, starting torque of 110 % and breakdown torque of 220 % give the drive reserve capacity when starting under load and during short-term process fluctuations. Rated current of 1367 A at △ 400V and 792 A at Y 690V supports the design of the switchboard, protection and soft-start or frequency-control system according to the requirements of the technology.
The motor operates with insulation class F and temperature rise B, helping maintain a stable thermal balance during long shifts. DE bearing 6328C3 and NDE bearing 6328C3 together with a weight of 4900 kg, external starting inertia of 524,000 kg·m² and a GD² moment of inertia of 52,000 kg·m² provide designers with data for precise foundation design and mechanical coupling.
In practice, this means fewer compromises when sizing the complete drive and better predictability when integrating into large technological systems. With the H17RL 450X1-4 model from VYBO Electric, you get a solution that meets the requirements of continuous production and robust OEM assemblies.
Take advantage of the offer for a motor that combines compact output, robust cast-iron construction and operating reliability for demanding industrial applications.
