This 900 rpm electric motor combines compact power with reserve capacity for continuous loading typical of large manufacturing units. The H17R 315-C-6-6 model delivers 220 kW and helps maintain stable operation when designing drives where torque, thermal resistance and long-term operational reliability are decisive.
The copper rotor reduces losses in the rotor winding while also withstanding thermal stress during repeated starts more effectively. For the operator, this means longer service life of the power-transmission arrangement over time, lower energy losses and more suitable behaviour in demanding cycles common in metallurgy, manufacturing and material processing.
900 rpm electric motor for continuous industrial drive
The IE4 class belongs to Super Premium solutions and in practice reduces energy consumption during long operating hours. This three-phase electric motor therefore fits well into lines where operating costs, thermal regime and output stability are monitored throughout the year.
The optional voltage version simplifies deployment in different power distribution systems and shortens the time required for technical adaptation of the drive. Customers can therefore work with variants for 3 300 V, 6 000 V, 10 000 V or 11 000 V without having to change the concept of the entire technology.
Compact shaft height and robust mechanics
The 315 mm shaft height simplifies design for existing frames where dimensional compatibility and sufficient mounting rigidity are important. A high-voltage electric motor with this foundation will appeal to mechanical engineers who need a reliable drive for equipment with high torque and variable load.

Bearings and diagnostics for longer service intervals
The bearing arrangement with 6322-C3 on both the DE and NDE sides supports operation with higher thermal and mechanical loads. Optional diagnostics through PT100 and PTC elements help service teams detect changes in the temperature regime early and prevent unplanned downtime.
The design with a rotor cage made of copper strip is suitable for a 6-pole electric motor where a balanced ratio between speed, torque and starting behaviour is required. With a rated current of 26,4 A and a power factor of 0,85, the drive can also be designed effectively for networks where electrical load stability is monitored.
Operational reliability in demanding production systems
During long production cycles, rated torque of 2135 Nm helps maintain the operating point without unnecessary output fluctuations. Rotor moment of inertia of 7,9 kg·m² is also important to designers because it affects behaviour during starting and transitions between load and no-load operation.
VYBO Electric is the largest company in its sector in Central Europe. This fact builds on technical practice where solution availability, service continuity and the ability to supply a motor for large industrial units without delay are decisive.
Copper rotor and IE4 efficiency for a long operating cycle
Copper rotor for long service life is particularly beneficial where the motor operates under load for long periods and where every kilowatt-hour is monitored in the production balance. With an efficiency of 94,8 %, system losses are reduced, which is important for operators of factories with continuous operation as well as medium-sized companies optimizing the energy intensity of their lines.
A weight of 2850 kg confirms the robust design, which is suitable for demanding technological units with high levels of vibration and long service intervals. If the project requires precise integration, this motor provides scope for drive design with an emphasis on reliability, stability and technical discipline.
When selecting a suitable configuration, you can use the range of VYBO Electric solutions and obtain a drive that supports long service life, economical operation and smooth running of industrial technologies.
