About the 4 kW 1000 RPM Electric Motor

In industrial operations, selecting the right motor is crucial for both efficiency and durability. For applications that require high torque at low speed, the 4 kW 1000 RPM electric motor is an ideal solution. Designed for heavy-duty continuous operation, it ensures safe and stable performance under demanding conditions.

Technical Specifications and Performance

Delivering 4 kW (approximately 5.5 HP) of power, this motor is built for medium to heavy industrial use. With its low rotational speed of 1000 RPM, it delivers high torque, making it perfect for machinery that needs strength rather than speed—such as lifting, pressing, or mixing systems.

Common Applications

The 4 kW 1000 RPM motor is commonly used in:

  • Industrial gear-driven machinery

  • Heavy conveyor systems

  • Mixers, agitators, and dosing equipment

  • Pumps (water, sludge, chemicals)

  • Presses and compacting machines

  • Lifting and hoisting systems

  • Grain transport systems in agriculture

Its robust performance under load makes it a reliable choice for intensive tasks.

Electrical Configuration and Drive Compatibility

These motors typically run on three-phase 380V systems and are compatible with:

  • Direct-on-line starters

  • Star-delta starters

  • Variable Frequency Drives (VFDs)

Using a VFD offers several advantages:

  • Adjustable speed control

  • Smooth start/stop operations

  • Energy savings

  • Protection from overcurrent and stress

  • Reduced wear and tear

Mechanical Design and Durability

Most 4 kW motors feature cast iron construction, offering high resistance to shock and vibration. The TEFC (Totally Enclosed Fan Cooled) enclosure ensures:

  • Protection from dust and moisture

  • Continuous cooling during operation

  • Stable performance even in harsh conditions

The bearing system is engineered for longevity, requiring minimal maintenance over time.

Energy Efficiency

These motors are offered in IE2 or IE3 energy efficiency classes, resulting in:

  • Lower energy consumption

  • Reduced carbon emissions

  • Cost savings on electricity

  • Support for eco-friendly operations

In systems operating 8+ hours daily, these motors can save substantial amounts of energy annually.

Conclusion

The 4 kW 1000 RPM electric motor is a powerful, efficient, and durable choice for any industrial system that prioritizes torque over speed. Whether used in conveyors, presses, pumps, or hoists, it delivers consistent, long-term performance and is a smart investment for any operation.
