Common cooling fans are categorized into EC, DC, AC, etc. An EC cooling fan is essentially a DC fan that converts AC to DC electricity. It can work with both DC and AC voltages, accommodating voltages of 12V, 24V, 48V, 110V, 220V, and 380V without the need for conversion.
Wellsunfan's EC cooling fan breaks the traditional AC fan's frequency limitation, significantly accelerating the fan's operating speed. It features a lightweight motor design, which reduces the air outlet area.
The motor of the EC cooling fan includes an internal intelligent control module that is a brushless DC and maintenance-free type. Its advantages include high efficiency, energy-saving, long service life, low vibration amplitude, low noise, and continuous, uninterrupted operation.
The structure of the EC cooling fan is simplified, enhancing the motor's manufacturability and mechanical reliability. It significantly increases the air gap magnetic density, allowing the motor to achieve optimal design and reducing the motor's size.
The EC cooling fan supports various speed control functions such as PWM, TC, and VC temperature control. It is very energy-efficient and can output various signals to monitor the fan's operating status in real-time.
The EC cooling fan handles high power and features soft start functionality. Its startup current is low, and it minimally impacts the power grid and equipment, thus ensuring high reliability.
The working principle of the EC cooling fan is based on electromagnetic induction and electronic commutation technology. The motor contains both a stator and a rotor. The stator generates a magnetic field, and the rotor generates rotational force under the magnetic field's influence. The electronic controller controls the current's direction and magnitude by detecting the motor's current and position information, thus achieving commutation and speed regulation.
EC cooling fans are widely used in various cooling-required scenarios, including but not limited to:
Industrial Equipment
Such as CNC machines, automation equipment, industrial robots, etc. These devices generate substantial heat during operation and require EC cooling fans for heat dissipation.
Electronic Devices
Such as computer mainframes, servers, switches, etc. These devices have numerous integrated electronic components and need EC cooling fans to maintain normal operating temperatures.
Automotive Field
Components like the battery packs and motor controllers of new energy vehicles require cooling, and EC cooling fans are crucial for dissipating heat from these parts.
