High-voltage electric motor 280 kW, 1482 rpm, 6 000 V, H17R-315-E-4-6

In heavy industrial production, pumping technology and technological systems where high power density is expected in limited space, H17R-315-E-4-6 with an output of 280 kW provides confidence for stable operation. This 1400 rpm electric motor is intended for applications where smooth engagement, long service life and sensible operating costs without compromises in drive sizing are decisive.

Compact 6000 V electric motor for space-saving deployment

The 6000 V electric motor from VYBO Electric is designed to provide full output even with spatial constraints imposed by switchboards, frames and foundations. The compact design within the 315 mm frame size makes integration easier both on new lines and when modernising existing units where continuity with mechanical and electrical interfaces must be maintained.

In practice, this is appreciated by operators of large factories dealing with process-water pumps, cooling-tower fans, compressor assemblies, conveyor routes, mixing units, crushers, rolling feeders and centrifuges. In such applications, the three-phase electric motor with carefully designed starting dynamics and efficiency that supports the energy efficiency of the entire technology can be fully utilised.

Copper rotor for long service life in continuous operation

The rotor design uses copper strip, which helps reduce losses while increasing thermal resistance under long-term load. For operations with frequent mode changes, this means lower thermal stress, better parameter stability and a longer service interval, which is especially important where a technology outage immediately affects the production plan.

This approach is suitable for applications such as raw-material processing mills, mixers for chemical operations, waterworks stations, pulp-processing machines, compressor stations, flue-gas extraction fans, belt-conveyor drives and heavy technological lines in metallurgy. In these regimes, the 4-pole electric motor maintains the required speed while supporting reliable long-term operation.

Temperature monitoring for control of bearings and winding

Advanced temperature sensing via PT100 in the winding and bearings helps operators respond before a small deviation becomes a shutdown. In motors of this class, this is an important element of predictive maintenance because it allows the thermal condition to be monitored during starts, steady-state running and transient modes.

DE 6322-C3 and NDE 6322-C3 bearing arrangements support stability under long-term load, while insulation class F and temperature rise B meet the requirements of industrial operation. The system is complemented by an anti-condensation heater, 6 x PT100 in the winding, 1 x PT100 in the NDE bearing, 1 x PT100 in the DE bearing and 3 x PTC thermistors, increasing control over machine condition in demanding conditions.

Parameters for drive design and starting behaviour

Rated torque of 1804 Nm, starting current of 5,4 % and a power factor of 0,88 give designers a good basis for designing the power supply, protection and soft-starter regime. At a rated speed of 1482 rpm, the motor integrates well into systems where consistent power transfer to pumps, fans or mixing mechanisms is important.

A starting-torque ratio of 0,83 % and breakdown-torque ratio of 2,3 % provide an additional basis for assessing operating behaviour under load. A weight of 3050 kg and rotor moment of inertia of 5,6 kg·m² can be used for precise calculation of acceleration time, mechanical stress and connection design for the technological system.

VYBO Electric for industrial drives with long-term operating reliability

VYBO Electric operates as a proven manufacturer and distributor supplying solutions for OEM manufacturers and end industrial operations with an emphasis on service readiness and technical continuity of deliveries. When designing new systems and replacing existing drives, precise integration into the technology and available support in selecting the appropriate connection help.

1400 rpm electric motor in applications with high operating load

For technological systems with continuous operation, the 1400 rpm electric motor is suitable where stable torque, sensible starting characteristics and a space-saving solution must be combined. This makes it suitable for pumping systems handling process media as well as drives where reliable cooperation with downstream automation is important.

Energy efficiency in operations where every kilowatt-hour is monitored

Efficiency of 95 % and a power factor of 0,88 support energy efficiency in operations where every kilowatt-hour and long-term operating costs are monitored. With the correct starting and cooling design, this approach is reflected in stable operation without unnecessary thermal loading of the surroundings.

For companies planning the modernisation of a pumping station, fan assembly or mixing node, this concept provides a sensible basis for a reliable drive with predictable behaviour. Combined with temperature monitoring and the rotor design, the motor creates a solution better suited to the requirements of today’s industrial lines.
