Electric motor 220 kW, 1480 rpm, 6000 V, H17R-315-C-4-6 MV

H17R-315-C-4-6 with an output of 220 kW is designed for drives where stable torque, long-term operation and reliable running in the speed range of 1400-1500 rpm are decisive. In practice, it is a solution for pumps, fans, compressors and large machinery units that need consistent performance with medium-voltage supply without unnecessary downtime. As a medium-voltage asynchronous electric motor from the VYBO Electric brand, this model is built for industrial deployment, where durability, precise workmanship and operational reliability are valued.

Speed range 1400-1500 rpm for drives with stable load

The rated speed of 1480 rpm fits exactly into the 1400-1500 rpm range, which simplifies the design of drives with industrial operating characteristics. With an output of 220 kW and a rated current of 25.5 A, the motor provides operation suitable for systems where smooth starting, stability in steady state and repeatable dynamics during long duty cycles are important. The power factor of 0.88 and efficiency of 94.8% support more economical operation in applications where energy costs are also monitored.

The frame size of 315 mm provides sufficient reserve for robust installation in technological assemblies and at the same time makes integration into existing machines easier. The frame size in this class helps achieve mechanical strength, which is essential under continuous load, especially in pumping and ventilation technology. Depending on the network, the motor can also be adapted for voltage levels of 3.3 kV, 6 kV, 10 kV or 11 kV, which gives designers room for a unified power supply solution across different plants.

Why the design improves durability in continuous operation

The rotor with copper bar construction supports very good electrical and mechanical properties under high load. The torque of 1420 Nm together with the Tst/Tn values of 0.74% and Tmax/Tn of 2.2% helps during starting and during steady power transmission to the technological line. The Ist/In value of 5.2% is important when designing the power supply and protective coordination, as it allows a more accurate assessment of motor behaviour during starting.

Insulation class F and temperature rise B are suitable for applications where long-term thermal stress is expected with reliable winding protection. A weight of 2900 kg and rotor inertia of 4.2 kg·m² indicate a robust mechanical structure, which is beneficial in operations with repeated load and a requirement for smooth running. For customers looking for energy-efficient industrial motors, it is also important that this 4-pole electric motor combines efficiency with high operational stability.

Equipment that reduces the risk of unplanned downtime

The DE 6322-C3 bearing and the NDE 6322-C3 bearing provide reliable rotor support under high-load conditions. The equipment includes PT100 winding and bearing sensors, an anti-condensation heater and three PTC thermistors, so the operation has a better overview of temperature and moisture risk before a fault occurs. Such a solution is especially helpful in environments with fluctuating temperature, during shutdowns or during longer idle intervals.

The medium voltage of 6000 V in this version is intended for industrial networks where a firm link between the motor design and the technological process is required. The combination of precise workmanship, premium materials and in-house development creates the basis for a long service life even in demanding daily operation. That is why this 6000 V electric motor is suitable for operations that want to reduce service interventions while retaining a power reserve.

Industrial applications of the medium-voltage motor

• Drive for centrifugal pumps in water supply and power generation.
• Drive for process pumps in chemical production.
• Drive for cooling fans in heat exchangers and condensers.
• Main drive for industrial fans for HVAC systems.
• Drive for blowers in technological lines.
• Drive for reciprocating compressors in manufacturing plants.
• Drive for screw compressors in medium-voltage substations.
• Drive for mixers in heavy process production.
• Drive for crushing and grinding equipment.
• Drive for conveyors with high load.
• Drive for large machines in continuous operation.

Operational reliability when integrating into medium-voltage lines

When designing the complete unit, not only the rated value is important, but also the motor behaviour during starting, acceleration and long-term load. This model offers a balanced ratio between efficiency, thermal resistance and mechanical robustness, which will be appreciated especially by operators who need stable operation of pumps, fans, compressors and heavy machines without frequent interventions in production.
