High-voltage electric motor 220 kW, 1480 rpm, 6 000 V, H17R-315-C-4-6

Compact output in the higher-voltage class is delivered by model H17R-315-C-4-6 with an output of 220 kW for operations that need stable pulling force and controlled starting under long-term load. This 1400 rpm electric motor is designed to perform well in technological systems where operating continuity, precise connection to the transmission system and predictable behaviour at the operating point are decisive.

1400 rpm electric motor for industrial drives with reserve

In the H17R Compact PRO-HV configuration, the three-phase electric motor operates so that it maintains balanced running under demanding use at rated speed. The rotor cage made of copper strip reduces rotor losses while supporting thermal resistance during long operating cycles, which is particularly beneficial under frequent load and process fluctuations.

• Copper rotor for long service life improves behaviour under continuous load and limits energy losses that would otherwise be converted into heat.
• IE4 Super Premium efficiency helps reduce operating costs in drives that run in multi-shift production.
• Voltage selection simplifies integration into existing networks and expands use in projects with different voltage standards.
• A shaft height of 315 mm creates a suitable basis for robust mounting in machines with higher torque requirements.

Efficiency and torque for heavy technological systems

When designing a drive, not only power reserve but also behaviour under changing load is important. The 4-pole electric motor in this class provides a balanced compromise between speed and torque, which is appreciated by designers of pumping stations, compressor units and conveyor systems with irregular cycles.

• Rated torque of 1420 Nm supports smooth starting of heavier units.
• A power factor of 0,88 helps when designing the power supply and sizing switchboards.
• Rated current of 25,5 A makes it easier to monitor operating conditions in the electrical section of the line.
• Rotor moment of inertia of 4,2 kg·m² helps stabilise operation in applications with dynamic load changes.

Design suitable for demanding deployment

Service predictability is also important for a high-voltage electric motor. DE bearing 6322-C3 and NDE bearing 6322-C3 support reliable rotor mounting over long service intervals, while a weight of 2900 kg corresponds to a robust frame for industrial machines and technological assemblies.

• Insulation class F increases winding resistance under thermal load.
• Temperature rise B helps keep operation within limits suitable for long cycles.
• High starting current requires proper adjustment of the power-supply system, which is a standard design step with HV electric motors.

Voltage adapted to the existing network

In production where the technology is already adapted to the distribution system, voltage selection without unnecessary intervention in the infrastructure is important. This H17R Compact PRO-HV series supports multiple voltage levels, allowing it to be integrated into new projects and reconstructions with different network concepts.

Such a solution performs well in mixing lines, mining conveyors, pressing machines, aggregate crushers, milling systems, incinerator fans, process-air compressors, cooling-water pumps, desulphurisation pumps, rolling lines, steel-strip winders, concrete mixers, polymer extruders and process-material dryers.

Operating support and temperature monitoring

For motors intended for continuous operation, it makes sense to monitor thermal behaviour directly in the winding and bearing points. The design of this model allows the use of elements that simplify service diagnostics and help prevent unplanned shutdowns at critical line nodes.

• 6 x PT100 in the winding supports more precise temperature-state monitoring during long-term load.
• 1 x PT100 in the NDE bearing helps monitor the mounting condition on the non-drive side.
• 1 x PT100 in the DE bearing provides additional monitoring of the drive side.
• An anti-condensation heater limits the risk of moisture when the machine is stopped.
• 3 x PTC thermistors supplement winding protection under thermal stress.
