Electric motor 185 kW, 1478 rpm, 6000 V, H17R-315-A-4-6 MV

Load fluctuations, long operating cycles and the requirement for a stable start often determine whether technology operates without downtime. The H17R-315-A-4-6 model with an output of 185 kW is therefore aimed at operations where the motor must deliver reliable performance in the speed range of 1400-1500 rpm while also maintaining precise control over the operation of the drive. Use in this segment is particularly valued by owners of equipment with high demands on production continuity, from pumps to compressors.

Stable performance for drives that must not lose momentum

This 6000 V electric motor is designed for demanding service where high efficiency, long service life and resistance to thermal stress are important. At a rated current of 22.5 A, rated speed of 1478 rpm and rated torque of 1195.4 Nm, it provides balanced performance for technologies that operate with variable load. An efficiency of 94.3 % and a power factor of 0.84 help reduce energy losses during normal operation.

From a design perspective, this is a three-phase 6 kV motor with insulation class F, temperature rise B and a rotor with copper bars, which supports durability under long-term load. The rotor inertia of 4.2 kg·m² helps smoother starting in systems where stable operating transitions are important. The 6319-C3 bearings on both the DE and NDE sides are selected for robust operation in an industrial environment.

Parameters that help manage protection and maintenance

• Rated current of 22.5 A supports more precise sizing of the power supply and protective elements.
• Rated torque of 1195.4 Nm provides a reserve for load peaks during starting and during steady operation.
• Tst/Tn 0.74 % and Tmax/Tn 2.2 % help assess starting behaviour in technology with frequent starts.
• Ist/In 5.2 % makes it easier to design the power supply and protection system in industrial distribution.
• Weight of 1750 kg indicates a robust design suitable for continuous service.
• Accessories include PT100 winding and bearing sensors, an anti-condensation heater and a trio of PTC thermistors for more accurate monitoring of the motor condition.

Application in high-load operations

In practice, this motor is suitable for pumping stations, fan assemblies, compressors, conveyor lines and large machine units where consistent operation and a good response to load changes are required. Thanks to its power class and robust mechanical construction, it ranks among suitable solutions for heavy industrial drives that must operate long term with minimal operator intervention. For operations with a 6 kV voltage infrastructure, it represents a balanced choice for stable and controlled operation.

Construction that supports long-term reliability

The frame size of 315 mm, that is a centre height of 315 mm, allows the motor to be installed in equipment where greater power reserve is required while maintaining industrial compatibility. The H17R Compact PRO-MV motor from VYBO Electric uses premium materials and in-house development, which translates into an emphasis on stability, service predictability and reliable purchasing for B2B operations.
