Introduction to fan-cooled gear motors for high-speed extruders.
Ein fan-cooled gear motor for high-speed extruders represents a robust and cost-effective solution, especially when considering the total cost of ownership (TCO). In systems with high operating times (over 2,000 hours per quarter), the careful consideration of purchase and maintenance costs for such drives for extruders is crucial. Modern air-cooled drive systems provide high power density.
Key requirements for these fan-cooled motors for extrusion systems include constant torque even under load, high tolerance to ambient temperatures, and resistance to abrasive dust. Current designs of these blower-cooled gear motors utilize advanced aerodynamics and special materials (such as reinforced plastic fan wheels or optimized cooling fins) to effectively dissipate over 90% of the losses generated in the motor. Proper design of the cooling system is of utmost importance for the longevity of the fan-cooled gear motor for high-speed extruders, even at ambient temperatures up to 45°C. Further details can be found at: innovative drive technology.Selection criteria for fan-cooled gear motors
Motor types and characteristics
The choice of motor type (induction, synchronous, DC) is a critical criterion when selecting a fan-cooled gear motor. Induction motors are considered particularly robust and often achieve over 60,000 operating hours, while servo motors (synchronous motors) provide high precision, which is required in applications such as medical technology extrusion. The selected motor type directly affects the energy efficiency (AC motors with frequency inverters can reduce consumption by up to 20%) and the control quality of the drive for extruders.
- Choice of motor type (induction, synchronous, DC) based on the specific requirements for robustness, precision, and energy efficiency of the fan-cooled gear motor for high-speed extruders.
- ensuring a constant cooling performance of the air-cooled drive system, even in high dust concentrations and ambient temperatures above 40°C.
- Selection of the appropriate IP protection class (at least IP55 is recommended) and a suitable cooling system for the blower-cooled gear motor.
- Correct design of the gear ratio to ensure the required torque at the extruder head.
- Coordination of voltage, power, and speed of the motor with fan cooling to the specific extruder and the existing power supply.
- Consideration of the torque-speed characteristic for optimal starting behavior of the high-performance extruder drive.
Cooling requirements
The cooling performance of a fan-cooled gear motor for high-speed extruders must remain constant even under difficult conditions such as high dust concentration and ambient temperatures above 40°C. The IP protection class (e.g., IP55 or higher) and the chosen cooling system (such as IC416 or specialized MENZEL airflow guides for dusty environments) are crucial for this. Insufficient cooling can reduce motor performance by up to 15% and shorten the lifespan of the drive by up to 50%.
Gear design
The correct gear design, especially the gear ratio, determines the torque available at the extruder head. A miscalculation in sizing the gear for the fan-cooled gear motor for high-speed extruders can reduce the production rate by up to 20% or lead to overload, especially when processing highly viscous polymers that require higher gear reductions. Planetary gears offer high power density in many applications.
Performance parameters and protection class
Voltage, power, and speed of the drive must be precisely matched to the extruder and the existing power supply (e.g., 400V/690V). The torque-speed characteristic is crucial for the operation of a fan-cooled gear motor, as for example a 75 kW motor must provide sufficient torque for the starting process even at low speeds. For a fan-cooled gear motor for high-speed extruders the protection class IP55+ is usually recommended.Advantages and disadvantages of fan-cooled gear motors
