H17RL 400X3-4 is a 4-pole electric motor designed for drives where high power density and stable operation under long-term load are decisive. This three-phase electric motor from VYBO Electric combines an output of 710 kW with a speed of 1488 rpm, giving designers and operators scope for precise sizing of technological systems without unnecessary installation reserve.
The solid cast-iron construction increases resistance to vibration, mechanical stress and demanding duty cycles. In large factories and OEM assemblies, this reduces the risk of unplanned downtime and helps the motor maintain its parameters even in applications with continuous process loads.
4-pole electric motor for demanding industrial systems
Thanks to its 400 mm shaft height and well-considered arrangement, this asynchronous electric motor with a squirrel-cage rotor is suitable where high output must be combined with limited installation space. Compact output simplifies integration into pumping stations, mixing lines and geared drives where not only performance but also assembly dimensions matter.
- Raw-water pumps in treatment plants and process distribution systems.
- Fan units for boiler rooms and dust extraction in production.
- Compressor stations in the energy and processing industries.
- Crushers in stone-processing and recycling operations.
- Mills and mixing equipment in cement plants.
- Rolling and conveyor lines with high loads.
Energy efficiency in continuous operation
Efficiency of 96,3 % and a power factor of 0,88 support lower losses during long periods of steady-state operation. Energy efficiency is particularly important in this power class where the motor runs for many hours every day and every reduction in efficiency affects the cost of the entire production line.
The option to choose the frequency simplifies deployment in projects involving both standard European operation and 60 Hz configurations. For integrators, this means fewer compromises in export assemblies and better adaptability to different technological platforms.
Bearing arrangement for long service intervals
DE 6326C3 and NDE 6326C3 bearings together with insulation class F and temperature rise B support stable operation in environments with higher loads. These elements are particularly important in an asynchronous electric motor with a squirrel-cage rotor that must handle starts, steady operation and process changes over the long term without losing operating reliability.
For operators of large factories, the weight of 3790 kg and robust mounting are also important because they help absorb the dynamic loads of the assembly. With an external starting current of 700 % and starting torque of 120 %, precise switchboard and protective-component design should be considered, especially for high-output technological nodes.
