Electric motor 1400 kW, 1492 rpm, 6000 V, H17R-500-B-4-6 MV

In heavy-duty operation, the stability of the drive determines the smoothness of the entire process, which is why H17R-500-B-4-6 with an output of 6000 V and a rated speed of 1492 rpm is designed to operate reliably in the speed class of 1400-1500 rpm. This medium-voltage asynchronous electric motor delivers a high output of 1400 kW in applications where long-term durability, precise integration into the assembly and a lower risk of unplanned downtime in production are required.

Energy-efficient operation with high efficiency and load reserve

The motor reaches an efficiency of 96.5 % and a power factor of 0.91, which helps to reduce energy losses during long operating cycles. A rated current of 153.9 A and a rated torque of 8961 Nm provide the necessary power reserve during starting as well as during steady-state operation, while the values Tst/Tn 0.7 %, Tmax/Tn 2.6 % and Ist/In 6.2 % support drive design with regard to grid conditions and load characteristics. For technologies where overall drive-system efficiency is monitored, this is a solution suitable for energy-saving industrial motors in demanding service.

Design ready for integration into medium-voltage infrastructure

The 500 mm frame size according to the IEC frame dimension makes mechanical integration into OEM assemblies as well as modernised lines easier. The motor can be designed for 3.3 kV, 6 kV, 10 kV or 11 kV networks, so it is well suited to projects with different levels of voltage infrastructure. The rotor inertia of 35.0 kg·m² supports predictable drive dynamics, and the copper-strand rotor cage is suitable for applications with an emphasis on thermal and electrical resistance. For integrators dealing with an electric motor for universal industrial applications, this is a practical basis for robust direct and geared drives.

Operating features that simplify service and supervision

Insulation class F combined with temperature rise B creates a favourable operating margin for longer loads. The weight of 7040 kg must be taken into account already in the base design, handling and servicing, as this is a powerful machine for fixed installations. The DE bearing and the NDE bearing are available on request, allowing the final configuration to be adapted to the project. Accessories include thermal protection with 6x PT100 in the winding, PT100 in the DE and NDE bearing, anti-condensation heating and 3x PTC, supporting continuous monitoring of the motor condition and timely response to changes in operating conditions.
