In heavy industrial operation where both operating stability and electricity consumption are decisive, H27R 5003-6-6 as a 900 rpm electric motor delivers in practice exactly what large pumps, compressors, conveyors and mills need. This high-voltage machine with an output of 1400 kW is intended for continuous load, where IE4 Super Premium efficiency translates into lower losses and better economics of continuous operation.
The H27R-HD-Modular series uses a welded steel frame that combines high rigidity with favorable weight for handling and installation of large drives. The motor design also supports the energy efficiency of the entire technological unit because it limits unnecessary thermal losses and helps keep operation stable. With this series, VYBO Electric also emphasizes standard thermal protection and monitoring, so the motor can be safely integrated into operations with continuous supervision of winding and bearing condition.
Precise speed and torque for process drives
Rated speed of 994 rpm together with rated torque of 13451 Nm creates a suitable operating profile for heavy starts and long-term load. This six-pole electric motor operates with a rated current of 162,5 A, power factor of 0,87 and efficiency of 95,6 %, which is especially important where return on operating costs is monitored. Starting torque reaches 1,1 times the rated torque, breakdown torque 2,2 times the rated torque and starting current 6,4 times the rated current, so when designing the power supply and protection, both torque reserve and starting load can be handled effectively.
Bearing arrangement and temperature supervision
H27R-HD-Modular motors are equipped with DE bearing NU238-C3+6040-C3 and NDE bearing NU230-C3, a solution suitable for the high mechanical demands of large rotating equipment. Insulation class F and temperature rise class B provide stable reserve under increased load, while standard thermal protection and monitoring help detect undesirable changes in operating condition in time. In practice, this is particularly appreciated by operators who require long service intervals and predictable maintenance.
Use in heavy industry and power generation
H27R 5003-6-6 is suitable for technologies where high torque, smooth operation and reliability in continuous duty are decisive. A 6000 V power supply allows efficient connection to high-voltage distribution systems in plants and power operations where the economy of the entire line is also monitored.

Parameters that simplify large-drive design
Rotor inertia of 78,0 kg·m² and load inertia of 1880,0 kg·m² provide important input for calculating starting and braking of the technological assembly. Package weight of 5700 kg is practical information for logistics, placement and preparation of installation in an industrial area. With a solution sized this way, output is combined with durable construction and emphasis on the long-term operational reliability expected by large factories and continuous-duty operations.
