The H17R 355-C-6-6 design delivers compact power for operations where reliable starting, stable loading and long-term operational reliability are decisive. This 900 rpm electric motor with an output of 315 kW is designed to handle continuous use in production lines, pumping stations and heavier process units.
The copper rotor in a cage made of copper strip reduces losses and helps maintain thermal reserve even during long operating cycles. This translates into longer service life and better resistance to repeated loading, which is typical of metallurgy, compressor stations and large conveying nodes. IE4 energy efficiency helps limit operating losses, which is particularly important wherever the motor runs for a large part of the day.
For operators of large factories, precise monitoring of drive condition is also important. Temperature monitoring through PT100 in the winding and bearings supports timely maintenance interventions and reduces the risk of unplanned shutdowns. In practice, this is valued by OEM manufacturers of technological units as well as service teams that need to keep the motor’s thermal behaviour under control before any output limitation occurs.
900 rpm electric motor for demanding processes with reliable starting
As a three-phase electric motor, this drive is suitable for applications where smooth torque transmission and precise connection to machine units are expected. A 6-pole electric motor with a rated speed of 989 rpm helps keep the process in a stable mode without unnecessary fluctuations.
- Pumping units for technical water with higher hydraulic resistance.
- Compressor assemblies for industrial air.
- Ventilation units for extensive production halls.
- Conveyor lines in the stone-processing and cement industries.
- Mills and crushers for raw-material processing.
- Mixing and homogenization equipment in chemical production.
- Rolling and feeding mechanisms in metallurgy.
- Extruders and technological drives in plastics production.
- Large drives for wastewater treatment plants.
Copper rotor for long service life in continuous operation
High rotor durability is beneficial wherever stable torque and minimal service downtime are expected from the drive. The copper rotor design handles thermal load better and helps reduce energy losses during long operation. This is a practical benefit for lines that have no room for frequent shutdowns or compromises in efficiency.
355 mm frame size for robust industrial installation
Mechanical readiness of the drive is also important for integration into a machine unit. The 355 mm frame size simplifies foundation design, connection to the transmission system and integration into existing technological assemblies. A weight of 3440 kg supports stability during operation with higher loads.
Maintenance support and available accessories
Available accessories expand diagnostic and protection options during operation. The assembly includes 6 x PT100 in the winding, 1 x PT100 in the NDE bearing, 1 x PT100 in the DE bearing, an anti-condensation heater and 3 x PTC thermistor, helping keep the motor ready for reliable starting even under less favourable conditions.
