The 750 rpm electric motor in the H17R 500-B-8-6 design delivers 900 kW for operations where energy efficiency translates into real savings as well as stable technology operation. This high-voltage electric motor from VYBO Electric is designed for large process and energy drives that require reliable torque, reasonable losses and long-term operation without unnecessary downtime.
IE4 Super Premium efficiency is particularly attractive to operators who monitor consumption in continuous cycles and want to keep costs under control even under high loads. The 6000 V electric motor in this design meets the demands of heavy industry with an emphasis on smooth starting, stability under changing loads and suitable sizing for long technological lines.
750 rpm electric motor for heavy technological systems
An eight-pole electric motor with a rated speed of 746 rpm is well suited where traction and controlled operation are priorities rather than unnecessarily high speed. Industrial 6 kV drives in this category are commonly used for equipment with high operating loads where precise coordination with gearboxes, pumps or compression technology is required.
Compact 6 kV motor with high integration reserve
A shaft height of 500 mm enables installation in assemblies where spatial discipline and maintaining output within a compact footprint are decisive. The design meets the requirements of large factories that expect full output within frames H315 to H560 without an unnecessary increase in installation demands. In practice, this facilitates drive modernization as well as replacement of older units in existing operations.
Special protection for demanding environments supports use in conditions where humidity, dust or increased environmental exposure are common. For technologies operating in more demanding surroundings, IP56, IP65, IP66 and IP67 variants are available, helping adapt the motor to the specific process without compromising assembly protection.
Maintenance and condition monitoring during long operating periods
Manufacturer VYBO Electric draws on years of experience reflected in an emphasis on service readiness and suitable monitoring of winding and bearing temperatures. Accessories such as 6xPT100 in the winding, 1xPT100 in the NDE bearing, 1xPT100 in the DE bearing, an anti-condensation heater and 3xPTC thermistor are also available, helping operators in metallurgy, the chemical industry and water management better protect the drive in real operation.
Use in processes where continuity is decisive
H17R 500-B-8-6 is suitable for agitators in chemical lines, mills in cement plants, centrifugal compressors in the energy industry, blowers for incineration plants, large water pumps, belt conveyors in mines, rolling stands, extruders in heavy manufacturing, homogenizing equipment and crushers in recycling lines. In each of these applications, a stable power curve helps reduce the risk of an unexpected drop in performance under full load.
You will particularly appreciate such a solution when the technology must run for long hours, the load changes in cycles and downtime directly affects production. Order this electric motor today if you need a motor for demanding operation with an emphasis on efficiency, reliability and readiness for integration into large industrial assemblies.
