Energy efficiency is a direct tool for reducing operating costs in large drives, and the 750 rpm electric motor in the H17R 400-B-8-6 version with an output of 355 kW is designed precisely for this type of use. In practice, this means stable output for technologies that run in continuous cycles and need reserve capacity for long service life, not just a good nameplate figure. For operators of large factories as well as OEM manufacturers, IE4 Super Premium efficiency means lower losses and better control over consumption across the entire drive chain.
750 rpm electric motor for economical operation of 6 kV lines
The design is adapted for a 6000 V electric motor with an emphasis on a compact solution without compromising output. A shaft height of 400 mm assists integration into machines where space is valuable while the robustness of the assembly must be maintained. Another advantage is that this 8-pole electric motor operates in a range designers favour for heavy conveyors, mills and pumping nodes with higher loads.
- In cement mills, it helps maintain a smooth flow of material.
- In steelworks fans, it supports even operation during long cycles.
- In quarry conveyors, it handles continuous mechanical stress.
- In compressor stations for industrial networks, it improves output stability.
- In pumping units for cooling circuits, it maintains predictable operation.
Advanced temperature monitoring for longer service intervals
Temperature diagnostics through PT100 in the winding and bearings give maintenance teams better visibility of what is happening before downtime occurs. Such a solution assists large technologies where it is important to detect a change in condition early and plan intervention at the right time. In this configuration, the high-voltage electric motor has better conditions for reliable operation in demanding industrial environments. An anti-condensation heater and sensing through a 3 x PTC thermistor are also available, which is practical in operation with fluctuating ambient temperature.
- In paper-machine winders, it protects operation during long shifts.
- In rubber-industry extruders, it supports a consistent technological process.
- In water pumping stations, it simplifies monitoring of drive condition.
- In aggregate crushing lines, it reduces the risk of unplanned downtime.
Confidence in supply for industrial projects
VYBO Electric is a proven manufacturer and distributor that has long supplied motors for industrial projects with high requirements for integration and service continuity. For planned modernizations and new lines, this approach is practical because it simplifies coordination of the drive with technology, maintenance and operational responsibility. Typical applications include mixing lines for bulk materials, cement-plant fans, main belt-conveyor drives, cooling-circuit pumps and compressor drives.
Solution for large technologies with an emphasis on operational reliability
When used in heavy manufacturing, the rotor moment of inertia is also important because it helps estimate system behaviour during starting and control more accurately. Copper strip in the rotor cage supports robust electrical and mechanical construction of the assembly, which is valuable during long operating cycles. If you need a motor for modernization or a new production assembly, order it in good time to maintain smooth project progress and deliveries.
Practical choice for continuous operation
H17R Compact PRO-HV is prepared for technologies where pressure on consumption, space and long service life come together. For demanding industrial applications, service reliability, compatibility with the control strategy and sensible shutdown planning are also important. If you are planning a drive replacement or installation in a new line, order the solution without delay so you can follow the production schedule without unnecessary downtime.
Use in industry where every operating hour counts
The motor is used in cement mills, steelworks fans, quarry conveyors, compressor stations, cooling-circuit pumping units, paper-machine winders, rubber-industry extruders, water pumping stations and aggregate crushing lines. In each of these applications, it provides the same benefit: stable running, better temperature control and a technical basis for long operation without unnecessary intervention.
