Product Overview


The 1TL0001 Series Low-voltage Variable Speed Three-phase Electric Motor is a cutting-edge high-efficiency low-voltage three-phase asynchronous motor designed by BEIDE, a leading manufacturer in industrial motor solutions. Engineered for continuous duty operation (S1), this motor features a rugged cast iron housing that delivers exceptional durability, enabling it to withstand harsh industrial environments and prolonged use without compromising performance.


What sets the 1TL0001 Series apart is its blend of efficiency and design innovation. It boasts a novel structural layout that enhances heat dissipation, a sleek appearance that fits modern industrial aesthetics, and advanced engineering to minimize low noise and small vibration—critical for maintaining a quiet and stable workspace. With a high degree of insulation, the motor also ensures safe operation even in conditions where electrical interference or moisture may be present.


Built to meet diverse industrial needs, the 1TL0001 Series supports flexible voltage and frequency configurations, making it adaptable to global power standards. Its core specifications—including a rated output range of 0.55 ~ 315 kW, frame sizes from 80 to 355, and a Class F insulation rating—position it as a versatile solution for both light and heavy-duty applications, from small fans to large compressors.


Product Features


Exceptional Power and Size Versatility

The 1TL0001 Series offers a broad rated output spectrum, spanning 0.55 kW to 315 kW, and frame sizes ranging from 80 to 355. This versatility eliminates the need for multiple motor models across different applications: it can power compact equipment (e.g., small ventilation fans) and heavy industrial machinery (e.g., large textile production lines) alike. The varied frame sizes also ensure easy integration into existing setups or custom systems, reducing installation time and costs.


Robust Protection and Cooling

Equipped with an IP55 degree of protection, the motor is dust-tight and protected against low-pressure water jets from any direction—ideal for factories, warehouses, or outdoor installations where dust, humidity, or occasional water exposure is common. Its cooling method, IC416 (self-ventilated with a separate fan), ensures efficient heat dissipation even during long operating cycles, preventing overheating and extending the motor’s lifespan. For motors with frame sizes 180 ~ 355, a standard oiling device is included to simplify maintenance and enhance bearing performance.


Converter-Fed Operation Compatibility

The 1TL0001 Series is optimized for converter-fed operation, a key requirement for variable speed applications. Its insulation system is designed to handle mains voltages up to 460 V when used with converters, ensuring stable performance across varying frequency inputs. For motors with frame size 250 and above, insulated bearings are recommended to prevent damage from bearing currents—a common issue in converter-driven systems—further boosting reliability.


Wide Environmental Adaptability

The motor operates efficiently in coolant temperatures ranging from -15 ºC to 40 ºC, making it suitable for cold storage facilities, hot manufacturing plants, and temperate outdoor environments. It also supports use at site altitudes not exceeding 1000 m above sea level, ensuring consistent performance in most industrial locations worldwide. When operated within its admissible torque range, the motor can rely on self-cooling; for loads exceeding this range, forced ventilation is recommended to maintain optimal temperature.


Applications


The 1TL0001 Series Low-voltage Variable Speed Three-phase Electric Motor is a go-to solution for industries requiring precise speed control, high efficiency, and durability. Its key application areas include:


Pump Systems

In water supply, wastewater treatment, and industrial fluid transfer, the motor’s variable speed capability allows precise adjustment of pump flow rates—reducing energy waste compared to fixed-speed motors. Its high efficiency and low vibration make it ideal for 24/7 pump operation, while IP55 protection ensures it withstands damp or dusty pump room conditions.


Fan and HVAC Systems

For heating, ventilation, and air conditioning (HVAC) systems in commercial buildings, factories, or data centers, the motor’s variable speed control enables tailored airflow management, cutting energy costs and improving comfort. Its low noise operation is critical for spaces like offices or hospitals, where excessive sound is disruptive.


Compressors

Industrial compressors (used in manufacturing, construction, or automotive industries) benefit from the motor’s 315 kW maximum rated output and converter compatibility. The motor delivers consistent power to drive compressors, while its Class F insulation and efficient cooling prevent overheating during high-load cycles.


Textile and General Machinery

Textile machines (e.g., looms, spinning frames) require precise speed control to maintain fabric quality— a need the 1TL0001 Series meets with its variable speed design. It also powers general industrial machinery like conveyors, mixers, and extruders, thanks to its robust cast iron housing and wide power range.


FAQ


Q1: Can the 1TL0001 Series motor operate at speeds above its rated speed?

Yes, the motor can operate above rated speed, but users should note key considerations: noise and vibration levels increase, and bearing life decreases at higher speeds. To mitigate these issues, ensure regular re-greasing of bearings (following manufacturer guidelines) and monitor grease service life closely. For applications requiring frequent high-speed operation, forced ventilation is recommended to maintain temperature control.


Q2: Is the motor compatible with global voltage and frequency standards?

Absolutely. The 1TL0001 Series Low-voltage Variable Speed Three-phase Electric Motor supports multiple voltage and frequency configurations, making it suitable for use in regions with 50 Hz (e.g., Europe, Asia) or 60 Hz (e.g., North America) power grids. Its insulation system is also optimized for mains voltages up to 460 V for converter-fed operation, further enhancing global compatibility.


Q3: What maintenance is required for the 1TL0001 Series motor?

Routine maintenance includes: checking and refilling the oiling device (for frame sizes 180 ~ 355) at recommended intervals; inspecting bearings for wear (especially critical for frame size 250+ motors using insulated bearings); cleaning the IC416 cooling system to prevent dust buildup; and verifying electrical connections to ensure safety. For converter-fed setups, periodic checks of the insulation system are also advised.


Q4: Is the motor suitable for outdoor use?

While the motor has an IP55 protection rating (dust-tight and water-resistant), it is not fully waterproof. For outdoor applications, ensure the motor is installed in a sheltered enclosure (e.g., a weatherproof cabinet) to protect it from heavy rain, snow, or extreme temperature fluctuations. Operating within the -15 ºC to 40 ºC temperature range and 1000 m altitude limit will also ensure optimal performance.
