The H27R-HD-Modular series is designed for large drives where both long-term reliability and energy consumption are decisive. The H27R 5003-2-6 model with an output of 1800 kW provides reserve for continuous operation and, thanks to high efficiency, reduces operating losses in demanding processes. It is a three-phase electric motor prepared for stable operation in power generation, raw-material processing and heavy industry.
2900 rpm electric motor for high loads with lower losses
A rated speed of 2988 rpm and rated torque of 5753 Nm support drives that need rapid response and smooth power transmission. Rated current of 196,6 A, a power factor of 0,91 and efficiency of 97,1 % provide scope for better energy efficiency under long-term loading. This 2-pole electric motor is suitable wherever high dynamics without unnecessary losses are expected from the motor.
Welded steel frame simplifies handling in heavy-duty operation
The 500 mm frame size is built on a welded steel structure that helps maintain rigidity at high output while simplifying transport and installation of the motor into the technological system. Insulation class F and temperature rise B support a safe thermal regime during stable deployment. In practice, this provides a reliable basis for drives where there is no room for unplanned downtime.
Starting and protection are prepared for demanding start-up
Starting parameters help design the power supply and protection for heavier starts where torque reserve is important. Starting torque reaches 0,6 times the rated torque, breakdown torque 2,9 times the rated torque and starting current 6,8 times the rated current. When designing the switchboard, protection and starting circuits, it is therefore advisable to allow reserve for short-term loading and suitable monitoring of winding and bearing temperatures.
Typical deployment in industrial lines
- Drive for large pumps in water management and power-generation units.
- Drive for compressors supplying compressed process air in chemical production.
- Drive for fans and blowers in combustion and extraction systems.
- Drive for agitators in metallurgical and technological tanks.
- Drive for conveyor lines in the mining and processing industries.
- Drive for rolling and winding units in high-load production.
- Drive for crushers and mills in bulk-material processing operations.
Bearing monitoring and heating reduce the risk of downtime
Standard thermal protection and monitoring help track the condition of the motor in real operation, which is especially valuable for a three-phase drive in environments with fluctuating load and temperature. Both DE and NDE bearings are available on request, simplifying maintenance design for a specific project. For higher power-supply requirements, operation at 6000 V is also considered so that the motor can be safely integrated into the technology without compromising operating availability.
A solution for large operations focused on return on investment
H27R 5003-2-6 with a package weight of 5650 kg, rotor inertia of 25,8 kg·m² and load inertia of 119,0 kg·m² is suitable for projects where long-term stability, economy and service predictability are monitored. VYBO Electric supplies a solution for industrial systems that need a reliable high-power motor with a clear benefit for operating costs.
