High-voltage electric motor 710 kW, 745 rpm, 6 000 V, H17R 450-D-8-6

In metallurgical lines, pumping technology and extensive conveyor systems, what matters is whether the drive can maintain the required pace without unnecessary downtime. H17R 450-D-8-6 delivers 710 kW in a design engineered for high power density and operation where energy must be transferred reliably into continuous service. This 700 rpm electric motor is suitable for equipment requiring smooth starting, stable traction and reserve capacity for long duty cycles.

The 6000 V electric motor in this design appeals to operators who need a compact solution without compromising integration into the technology. In practice, this means lower space requirements in the machine room, simpler arrangement of the drive assembly and better use of space in machinery systems. At the power level typically expected by larger factories and OEM manufacturers, it is important that the motor can deliver full output within a frame that also fits well into existing projects. This compact 6 kV motor is therefore especially attractive where every meter of space and every hour of downtime matters.

700 rpm electric motor for smooth operation of large technological systems

Rated speed of 745 rpm supports applications where controlled torque transmission and stable operation under high load are priorities. An eight-pole electric motor behaves predictably in such applications and enables good coordination with gearboxes, pumps or agitators. For the operator, this means fewer corrections when fine-tuning the drive and better production continuity during load changes.

Copper rotor that keeps losses under control

The copper alloy of the rotor helps limit energy losses while increasing thermal resistance in operations with long-term stress. This is why the copper rotor is suitable for applications where the motor frequently operates close to its operating maximum and where long service life without frequent machine interventions is expected. In practice, this is particularly appreciated by those who plan service shutdowns in advance and want to keep total cost of ownership under control.

The design is based on a 450 mm frame size while retaining space for effective cooling and reliable mounting in demanding industrial environments. This makes the motor suitable for integration into new lines as well as modernization projects where existing installations must be retained without extensive construction work. Such a solution is well suited to drives that must operate for long periods without unnecessary overheating.

Frequency selection for 50 Hz and 60 Hz operation

The ability to operate under different network conditions facilitates deployment in projects with an international reach. If a customer operates technology in Europe and elsewhere, availability of a version for 60 Hz helps standardize the drive concept and reduce the number of different components in spare-parts inventory. For OEM manufacturers, this is a practical advantage when standardizing assemblies and supplying multiple regions.

A three-phase electric motor of this type is suitable for drives where smooth operation, a good torque profile and resistance during starting of loaded equipment are important. Class B temperature rise combined with class F insulation creates reserve capacity for operating conditions where the motor encounters load fluctuations, dust or higher ambient temperatures. For these motors, VYBO Electric draws on practical experience familiar to continuous-operation plants and also bases production on ISO certificates.

Strong starting for demanding applications with high inertia

Torque of 9101 Nm helps in technologies with high inertia, where the motor’s ability to bring the system into operation without unnecessary overloading is decisive. The starting and breakdown ratios are set so that the drive behaves predictably during typical industrial starts. Combined with a rated current of 87,2 A and power factor of 0,82, the operation has a solid basis for stable energy management across the entire line.

6328-C3 bearings on both the DE and NDE sides support long-term reliability in continuous operation. A weight of 5700 kg and rotor moment of inertia of 25,0 kg·m² give the drive the robustness required for applications where mechanical durability and smooth running are expected. An anti-condensation heater, PT100 temperature sensors in the winding and bearings, and three PTC thermistors help keep the motor condition under control during shutdowns and when starting after a cold start.

Use in lines where availability and service logic are decisive

This motor is suitable for operations that need to combine performance with sensible serviceability and simple integration into the control system. This makes it well suited to technologies requiring long-term stability and where it is important to have an overview of bearing condition, winding and thermal regime. For drive technology in heavy production, it is a solution that helps keep production cycles under control.
