Product Features


IE3 Efficiency Class for Superior Energy Savings

As an IE3 (International Efficiency Class 3) certified motor, the 1TL0003 Series sets a high bar for energy efficiency. Compared to lower efficiency classes (e.g., IE1 or IE2), it reduces energy consumption by up to 10-15% during long-term operation – a critical advantage for businesses seeking to lower electricity costs and comply with global environmental regulations (such as the EU’s ErP Directive). This efficiency not only cuts operational expenses but also minimizes carbon emissions, aligning with sustainable development goals for modern industries.


Robust Construction & Low Operational Noise/Vibration

The 1TL0003 Series features a novel structural design with a focus on durability and user comfort. The cast iron housing (or optional aluminum) provides excellent mechanical strength, resisting impact and wear in harsh industrial settings. Additionally, the motor’s optimized internal structure and precision manufacturing reduce noise levels and vibration during operation. This design not only extends the motor’s service life by minimizing mechanical stress but also creates a quieter working environment, which is particularly valuable for facilities where noise control is a priority (e.g., textile mills or food processing plants).


Reliable Protection & Wide Environmental Adaptability

Equipped with IP55 / IP56 protection, the 1TL0003 Series effectively shields internal components from dust ingress and low-pressure water jets – essential for operations in dusty (e.g., cement plants) or damp (e.g., water treatment facilities) environments. The Class F insulation rating ensures the motor can withstand high temperatures without insulation degradation, while its ability to operate in a coolant temperature range of -15 ~ 40 ºC and at site altitudes not exceeding 1000 m makes it suitable for use in diverse geographic locations, from cold northern regions to low-altitude industrial zones.


Flexible Configuration Options for Custom Needs

To meet specific application requirements, the 1TL0003 Series offers tailored configurations. For motors with frame sizes FS180~355, an oiling device is included as standard, simplifying maintenance and ensuring smooth lubrication during long-term use. Additionally, users can opt for a disc-type DC electromagnetic brake, which enables fast stopping, accurate positioning, and reciprocating operation – perfect for equipment like conveyors, lifting machinery, or automated production lines that require precise motion control. The motor also supports multiple voltage and frequency combinations, eliminating compatibility issues for global customers.


Applications


The 1TL0003 Series IE3 Low-voltage Three-phase Electric Motor is engineered to excel in a wide range of industrial applications, thanks to its high efficiency, durability, and flexible design. Its core use cases include:

Fans & Ventilation Systems: The motor’s continuous duty (S1) rating and low noise operation make it ideal for powering industrial fans, exhaust systems, and HVAC units in factories, commercial buildings, and data centers. Its IE3 efficiency reduces energy costs for systems that run 24/7.

Pumps & Water Treatment Equipment: With IP55 / IP56 protection and resistance to damp environments, the motor reliably drives centrifugal pumps, submersible pumps, and water circulation systems in municipal water treatment plants, agricultural irrigation, and industrial fluid transfer processes. The stable power output (0.55 ~ 315 kW) ensures consistent pump performance.

Compressors & Air Conditioning Units: Compressors require motors with high torque and energy efficiency – two strengths of the 1TL0003 Series. It powers reciprocating and rotary compressors in refrigeration systems, air compressors for manufacturing, and commercial AC units, where its Class F insulation handles the heat generated during compression.

Textile Machinery: Textile mills demand low vibration and precise speed control to avoid fabric defects. The 1TL0003 Series’ low vibration design and optional braking system make it suitable for spinning machines, looms, and dyeing equipment, ensuring smooth operation and high product quality.

General Industrial Machinery: Beyond the above, the motor is widely used in conveying systems (e.g., belt conveyors for mining), machine tools (e.g., lathes and milling machines), and agricultural machinery (e.g., grain harvesters). Its versatile frame size (80 ~ 355) and voltage compatibility allow it to integrate with various equipment types, making it a go-to solution for diverse industrial needs.


FAQ


What does the IE3 efficiency class mean for the 1TL0003 Series motor?

The IE3 (International Efficiency Class 3) is a global standard set by the International Electrotechnical Commission (IEC) to measure motor energy efficiency. For the 1TL0003 Series, IE3 certification means it consumes significantly less energy than lower classes (IE1, IE2) – typically 10-15% less during continuous operation. This translates to lower electricity bills for users, especially for motors running 8+ hours daily. Additionally, IE3 compliance meets strict energy regulations in regions like the EU, North America, and China, making the motor suitable for global markets without needing design modifications.


What are the differences between the cast iron and aluminum housing options for the 1TL0003 motor?

The 1TL0003 Series offers two housing materials to match application needs:

Cast iron: Provides superior mechanical strength and heat dissipation, making it ideal for heavy-duty environments (e.g., mining, construction) or motors with higher power outputs (closer to 315 kW). It resists impact and wear better than aluminum, extending the motor’s life in harsh conditions.

Aluminum: Is lighter (up to 30% lighter than cast iron) and corrosion-resistant, making it suitable for applications where weight is a concern (e.g., mobile equipment, light industrial machinery) or environments with mild corrosion risks (e.g., food processing plants with frequent cleaning). Both options maintain the motor’s IP55 / IP56 protection rating, so durability is not compromised regardless of choice.


Can the 1TL0003 Series motor operate in extreme temperature or high-altitude environments?

Yes. The 1TL0003 Series is designed to adapt to challenging environmental conditions:

Temperature range: It operates reliably in coolant temperatures from -15 ~ 40 ºC, meaning it can handle cold climates (e.g., northern Europe, Canada) without freezing issues and warm industrial settings (e.g., steel mills) without overheating, thanks to its IC411 cooling method and Class F insulation.

Altitude: The motor is rated for site altitudes not exceeding 1000 m above sea level. For higher altitudes (e.g., mountainous regions), Copartner Technology can provide custom modifications to adjust cooling performance, as thinner air at high altitudes reduces natural heat dissipation.


Does the 1TL0003 motor come with a braking system, and when is it needed?

The 1TL0003 Series offers an optional disc-type DC electromagnetic brake for specific use cases. This brake enables:

Fast stopping: Reduces the motor’s stop time by 50-70% compared to free coasting, critical for equipment like conveyors or cranes that need to avoid collisions.

Precise positioning: Maintains the motor’s position when stopped, ideal for automated machinery (e.g., assembly lines) that requires accurate part alignment.

Reciprocating operation: Supports frequent start-stop cycles without overheating, suitable for equipment like textile looms or packaging machines.
If your application only requires continuous, slow-stop operation (e.g., a standard fan), the brake is not necessary – the motor’s default design will work efficiently.


What is the “continuous duty (S1)” rating of the 1TL0003 motor, and why is it important?

Continuous duty (S1) is an IEC rating that means the 1TL0003 Series can operate at its full rated load (0.55 ~ 315 kW, depending on the model) for an unlimited period without overheating or performance degradation. This is critical for industrial applications that require 24/7 or long-duration operation (e.g., water pumps, industrial fans, compressors). Unlike motors with intermittent duty ratings (e.g., S2, S3), the 1TL0003 Series does not need cool-down periods between cycles, ensuring uninterrupted productivity for businesses that rely on constant equipment operation. The motor’s Class F insulation and IC411 cooling system work together to maintain this S1 rating, even in high-load scenarios.
