The H27R-HD-Modular series provides large industrial units with a solution combining economical operation and high operational reliability. The H27R 5003-8-6 model with an output of 1120 kW is suitable where a 750 rpm electric motor must ensure long-term and even output under high load without unnecessary energy losses.
The closed cooling circuit with a heat exchanger for IC611 air-to-air cooling helps keep the motor’s internal environment clean and supports use in dusty and corrosive operations. IE4 Super Premium efficiency also reduces losses during continuous operation and provides a better ratio between energy consumption and delivered output in drive technology.
Energy balance of large drives remains under control
The motor design uses parameters important for both power-supply and protection design. Rated current reaches 132,8 A, power factor is 0,85, efficiency 95,8 % and insulation belongs to class F with temperature rise class B. For operations with higher reliability requirements, starting reserve is also important, with starting torque reaching 1 times the rated torque, breakdown torque 2,2 times the rated torque and starting current 5,9 times the rated current.
- Excels in long operating cycles with emphasis on energy economy.
- Supports stable operation of large technological units without unnecessary overheating.
- Allows more precise sizing of starting and protection components.
Mechanical assembly supports long service life in heavy operation
The model is built as an 8-pole electric motor with a rated speed of 744 rpm, which suits heavier drives with higher torque reserve. Rated torque of 14376 Nm, rotor inertia of 111,0 kg·m² and load inertia of 2650,0 kg·m² give the project the data needed to assess system dynamics. DE bearing type NU238-C3+6040-C3 and NDE bearing type NU230-C3 contribute to reliable shaft guidance under long-term load.
Winding resistance in demanding applications
The stator winding is impregnated using VPI technology, increasing resistance to moisture, dust and vibration. This layer of protection is beneficial in applications where a high-voltage electric motor is exposed to continuous mechanical stress and fluctuating conditions around the drive.
Use in high-load industry
This model is used to drive rolling stands, crushers, mills, agitators, blowers, compressors, process-water pumps, conveyor lines, belt conveyors in mining, fans for power generation, extractors, drainage systems and auxiliary drives in cement plants. In each of these applications, the combination of high output, stable speed and reliable cooling is important.
Decision for long-term operation
Package weight of 5430 kg corresponds to robust construction intended for demanding handling and installation in industrial units. If you are planning modernization or a new project for large process technologies, order H27R 5003-8-6 in time to secure a suitable delivery date and continuity of implementation. VYBO Electric offers a solution prepared for reliable operation in demanding conditions.
