Compact output for industrial drives with high power density
H17RL 400X4-4 from VYBO Electric provides a solution for operations that need compact output without unnecessarily increasing the installation footprint. This 1500 rpm electric motor is designed for technologies where smooth energy transfer, precise integration into the drive line and reserve capacity for long-term loading are decisive.
Thanks to an output of 800 kW and a shaft height of 400 mm, the motor is suitable for assemblies where high power density and reliable continuous operation are required. For operators of large factories and OEM manufacturers of large technological systems, this means easier drive sizing and lower requirements for the surrounding structure.
Three-phase electric motor with reserve capacity for starting and load
As a three-phase electric motor, this model is suitable for applications where stable starting, controlled acceleration and good behaviour under variable load are important. Rated torque of 5134 Nm provides capacity for driving equipment with higher inertia and more demanding duty cycles.
A starting torque ratio of 120 % and breakdown torque ratio of 220 % help in applications where a reliable motor response is expected from the initial stage of starting. A starting current ratio of 700 % must be taken into account when designing the power supply, particularly when integrating the motor into larger technological systems.
Low-voltage electric motor for robust power-supply assemblies
As a low-voltage electric motor, it operates at 400/690 V, simplifying integration into industrial distribution systems and standard control systems. Rated current of 1363 A at △ 400V and 790 A at Y 690V gives designers the data needed to set protection, starting components and cable routes correctly.
Rated speed of 1488 rpm supports use in drives requiring steady operation and smooth transfer of power into the technological line. A power factor of 0,88 and efficiency of 96,3 % also help keep the energy balance under control during longer duty cycles.
Robust cast-iron construction for demanding use
Robust cast-iron construction increases mechanical resistance, stability and resistance to vibration, which is essential in industrial operation. A weight of 4000 kg helps damp unwanted dynamic effects and contributes to rigid mounting of the motor in the machine frame or technological assembly.
Insulation class F and temperature rise B provide an operating framework for long-term loading in environments where the motor must not overheat during normal duty. When designing modern production lines, this combination is appreciated by operators monitoring availability, service intervals and total life-cycle costs.
Advanced lubrication and maintenance for long service intervals
For technological systems, it is important that the motor uses bearing relubrication during operation, simplifying maintenance and reducing the risk of unplanned shutdown. DE 6326C3 and NDE 6326C3 bearings support reliable running under loads typical of large industrial drives.
Years of experience at VYBO Electric can be seen in how the motor addresses operating details that determine service readiness in practice. A GD² moment of inertia of 52,000 kg·m² and external starting inertia of 524,000 kg·m² provide designers with important data when coordinating starting with downstream technology.
