Electric motor 1250 kW, 995 rpm, 6000 V, H17R 500-C-6-6 MV

In heavy-duty operation, where the drive must handle long-term load and stable running, the H17R 500-C-6-6 model with an output of 1250 kW provides a solution for technologies with high energy demand. For the speed class of 900-1000 rpm, it is particularly suitable where a balance of torque, efficiency and reliable starting is required at the voltage level of 6000 V. This is a 6000 V electric motor that naturally fits operations with strict demands for continuity and service predictability.

Torque output for heavy industrial technologies

The motor design is aimed at stable power transmission at a rated torque of 11997 Nm, which is important in applications with variable load and long cycles. A rated current of 145.4 A, a power factor of 0.86 and an efficiency of 96.5% support economical operation in energy-intensive units. For integrators, it is also important that the three-phase 6 kV motor operates with parameters suitable for robust electric drives and minimisation of operating fluctuations.

Speed class 900-1000 rpm for stable operation

In the 900-1000 rpm speed class, the motor provides a rated speed of 995 rpm, which is advantageous for drives that require smooth integration into the technological process. The Tst/Tn value of 1.1% and Tmax/Tn of 2% complement the picture of a motor intended for operation where both starting and transient states are monitored. The rotor inertia of 48.0 kg·m² helps when assessing the dynamics of the drive already in the design phase of the machine or the entire line.

Safety features and service readiness

For reliable monitoring of operation, the motor is equipped with PT100 sensors for the windings and bearings, an anti-condensation heater and three PTC thermistors, which support early evaluation of the thermal regime. Insulation class F together with temperature rise B creates a suitable reserve for operating load, while the copper band in the rotor cage contributes to durability during repeated starts and longer service life. DE and NDE bearings are available on request, which makes it easier to adapt the motor to a specific application and service strategy.
