Electric motor 450 kW, 988 rpm, 6000 V, H17R 400-B-6-6 MV

Electric motor H17R 400-B-6-6 with an output of 450 kW brings a practical reserve for operations that need reliable torque and smooth starting in the speed class of 900-1000 rpm. It is a three-phase 6 kV motor designed for technologies where stability, efficiency and long-term durability under load are decisive. The design is suitable for modernisations as well as direct replacements in sectors where high drive availability and precise connection to existing infrastructure are required.

Efficient energy transfer in higher-load operation

Rated current of 53.5 A, rated speed of 988 rpm and rated torque of 4350 Nm create parameters that match demanding technological units well. An efficiency of 95.7 % helps reduce energy losses in long operating cycles, and a power factor of 0.85 supports more economical use of the electrical network. For companies planning a reliable 6000 V electric motor, stability during repeated starts and continuous operation is also important.

Safer operation in the 900-1000 rpm range

In this speed class, it is especially suitable where constant output must be maintained without unnecessary fluctuations. Values of Tst/Tn 1.1 % and Tmax/Tn 2.3 % together with Ist/In 6.1 % help better estimate drive behaviour during starting and under load. For the production process, this means better predictability when planning starts, control and subsequent technological steps.

Design ready for long-term industrial use

Insulation class F and temperature rise B strengthen thermal resistance during prolonged operation, while a weight of 4110 kg reflects robust construction for heavier applications. Rotor inertia of 12.5 kg·m² supports smooth running in mechanically demanding machine connections. The rotor cage is made of copper bars improves conductivity and helps with efficient transfer of energy to the mechanical load.

Bearing solution for stability and service confidence

The DE 6326-C3 bearing and the NDE 6326-C3 bearing are selected for reliable operation under high load and long operating intervals. In combination with accessories including PT100 winding and bearing sensors, an anti-condensation heater and three PTC thermistors, the operator gains a better overview of the motor condition even during demanding starts or ambient fluctuations. Such a solution is valued by heavy industry drives, where minimising unplanned downtime is a priority.

Industrial applications of the medium-voltage motor

This 6-pole electric motor is suitable for conveyors, pumps, fans, compressors, mixers, crushers, mills, extruders, winches, rolling lines, lifting technology, cooling towers, technological dust extraction, raw material treatment plants and plant energy management. It is also suitable for operations with medium-voltage distribution, where stable output is required during long-term use and compatibility with industrial automation.
