The 3000 rpm electric motor in the H17R-450-A-2-6 version is designed for operations where stable output, sensible energy consumption and long-term operating reliability are expected from the drive. This 6000 V electric motor with an output of 800 kW is suitable for lines that run under high load throughout the entire shift because IE4 Super Premium efficiency helps keep energy costs under control without unnecessary downtime. In large factories and energy operations, it therefore performs well where every operating hour matters.
IE4 efficiency for 6 kV industrial drives with lower losses
High efficiency is particularly noticeable in large drives during long daily operating periods. 6 kV industrial drives from this series use a design that supports economical operation even under continuous load. In practice, this means less waste heat, a better thermal regime and more favourable conditions for downstream technological systems. For the operator, this is not merely a nameplate value but real room for more efficient use of installed power.
The main benefit of quiet and stable operation is complemented by a design suitable for demanding industrial drives where the motor operates with high requirements for continuity and durability. VYBO Electric has long built solutions for segments that need reliable deployment in energy, heavy industry and process production. The result is a motor that fits modern technological systems without requiring unnecessary compromises in drive sizing.
Compact high-voltage electric motor in a 450 mm frame
The 450 mm shaft height makes integration into existing machine systems easier while preserving space for service access. A two-pole electric motor with this arrangement provides full output in a frame that performs well across the H315 to H560 range, which is important in modernisation projects and when replacing older units. The compact solution helps designers when specifying foundations, couplings and downstream mechanics.
In this class, operating stability under changing load conditions also plays a role. The high-voltage electric motor therefore finds its place in applications where precise coordination with the technological line and long service life without frequent intervention are required. Industrial systems gain a drive that can be sensibly integrated into both new and modernised assemblies.
Special protection for demanding environments in heavy production
For equipment in dusty, humid or more aggressive environments, special protection is also available to increase confidence in real production deployment. The 3000 rpm electric motor therefore fits better into operations with continuous load, fluctuating ambient conditions and a requirement for long service intervals. This approach is particularly appreciated by lines that must not stop because of increased environmental exposure.
Control and monitoring in continuous operation
Available accessories extend monitoring of motor condition in everyday operation. 6xPT100 in the winding, 1xPT100 in the NDE bearing, 1xPT100 in the DE bearing, an anti-condensation heater and 3xPTC thermistors help monitor temperature conditions more effectively and prepare the machine for starting even after a shutdown. Such equipment is useful where 6 kV industrial drives operate with minimal room for unplanned intervention.
Model H17R-450-A-2-6 is suitable for pumping stations, compressor assemblies, crushers, mixing units, belt conveyors, vacuum pumps, mills, fan units, extruders, winding stands, dewatering pumps and process mixers. In these applications, the high-voltage electric motor is used where demanding operation in large plants and energy systems must be handled reliably.
If you need a motor for long-term load and precisely designed 6 kV industrial drives, order H17R-450-A-2-6 as soon as possible and secure a solution for both current and planned projects. VYBO Electric brings years of experience to every design, which is reflected in reliable deployment and demanding operating cycles.
