Brushless DC fans andblowers需要最佳运动控制。金宝搏188bet官网当复杂或要求苛刻的应用需要精确的输出水平时，智能运动控制系统可以保持零件安全，同时仍然可以确保高质量的生产周期。金宝搏188bet官网这些intelligent motion controls (IMCs)have in-board circuits that use programmable, information-gathering features to develop air movement “intelligence” and learn how the parts need to operate in different environments.

IMCs are ideal for:

• 绿色应用程序，其中设施经理想要提高可靠性，设备的预期寿命和能效。
• Systems that need consistent monitoring and cooling—IMCs have multi-alarm connections to prevent complete system failures, reduce voltage fluctuations, and have more reliable control.

When businesses install IMCs, they will make their facilities greener and more efficient. Read on to learn about all the different benefits IMCs can bring.

Top Solutions

There are several different types of IMCs that can add control to the operation and maintenance of brushless DC fans and blowers. The top four IMC solutions are:

旋转探测器

A smart rotation detector can monitor fan operations in parallel circuits to detect ongoing circulation as well as potential failures or stopped fans. These systems give a “high” output signal to the monitoring interface while the fan rotates. That same signal turns to “low” or “off” based on the fan’s status. This allows operators and maintenance teams to investigate potential problem areas more quickly because the system automatically notifies them when a fan stops working rather than requiring them to monitor changes in temperature.

旋转探测器使用与频率发生器（转速计）相同的硬件，我们还描述如下。一旦探测器添加到粉丝阵列中，它就像设施的多报警连接一样运行。

Inrush Current Protection

当电机，加热元件，变压器和电源开启时，电流浪涌。如果没有正确控制，这种短寿命的浪涌电流可能会损坏电子部件。

设施管理人员使用浪涌电流保护来减缓电流的洪水。这种技术允许风扇刀片通过增量增加的电流以更逐渐逐渐加速。该过程在启动期间需要大约十秒钟，并且它可以保护电路和移动部件免受损坏。

自动启动

Sometimes, fan blades get blocked by temporary obstructions. Auto starts control the current output in these circumstances. First, the current can be reduced to zero when an obstruction is detected so the fan blades don’t damage themselves. This feature is called locked rotor protection. Then, the auto-start control uses a second feature, restart with current limit, to guarantee the restart of the rotor once it is released.

频率发生器(Tachometer)

该IMC解决方案是开放的集体输出类型，可根据风扇电机速度产生模拟电压。这些部件提供反馈，可用于测量电动机，转子和发动机的速度。

Frequency generators use the same hardware as rotation detectors, and they’re powered by the power supply voltage. A tachometer will send a square wave signal to the reading device if the collector connects with a pullup resistor. This part can handle a maximum collector voltage of 72 V DC and current of 10 mA.

如何提供最好的问题cooling for industrial applicationshas been around since the earliest days of the industrial revolution. When equipment is functioning at a high level, it often produces heat that needs to be dissipated, and today, facilities are using systems that are more advanced than ever.

With the advances in technology that are so commonplace in today’s industrial landscape, many systems are being designed to provide the greatest power possible in the smallest possible space. These systems can run the risk of overheating if they are not designed with an appropriate cooling mechanism.

过热的设备可以提出许多风险，包括设备性能差，早期部件和润滑剂恶化，整体系统故障，最终是用户和操作人员的火灾和其他安全风险的可能性。

为了避免这些问题，设计工程师需要为这些系统选择合适的冷却单元。188体育在线官方188d金宝搏的网址一种流行和经济的选择是使用冷却风扇。金宝搏188是什么公司188体育在线官方188d金宝搏的网址188d金宝搏的网址188体育在线官方金宝搏188是什么公司根据项目的温度需求，冷却风扇可提供各种选项。设计者需要考虑选择最佳冷却应用的一些考虑因素包括单位，电压和涉及噪声的大小。188体育在线官方188d金宝搏的网址

Different Sizes for Different Applications

Just as mechanical systems can come in all different sizes, the dimensions of cooling fans also vary greatly in order to ensure the best temperature stability. This process is usually begun by thermal analysis, which is used to ascertain how much heat is generated inside systems in order to find out how much cooling is necessary.

After this has been determined, a design engineer can then choose the proper sized cooling unit. The exact size needed can be determined according to the sizing and density of the individual application. For instance, cooling units for computers often need to be placed in very small spaces, and therefore will need to be designed to run at a high speed.

By calculating the space available and how much cooling is needed, the appropriate fan can be chosen or designed as needed. Knowing the desired temperature is also necessary for choosing a fan for large scale applications. Larger fans can be used in applications such as locomotive engines that need a large volume of air constantly blowing to keep the engine and engine fluids cool.

粉丝of this size are not only used to keep equipment cool, but also to maintain comfortable temperatures for personnel working in industrial environments. Cooling fans for HVAC systems can ensure that all workers are safe and comfortable, and usually are required on a large scale.

High or Low Voltage

The power supply used for a fan will influence its size and many other aspects of its operation, and must be taken into consideration when choosing the best cooling system. The voltage that a fan requires will be dependent on its size and speed. The parameters that best represent the voltage needed can be found in a fan performance curve.

Certain models, such asDC粉丝，建立直接与电压成比例，使它们在能量消耗方面具有高效。这些型号还可以设计有电路，这些电路可在操作中减少电压尖峰，提供有效和平滑的冷却结果。188体育在线官方188d金宝搏的网址

Noise

There are many different factors that can influence the noise level associated with fan operation. The amount of noise that comes from a fan is determined in part by how big the fan is and how fast it spins. Essentially, the faster a fan operates the more noise it produces.

A larger fan running at lower speeds can produce the same energy with less noise than a smaller fan running at a high speed. However, these types of size adjustments are not always practical, depending on the size requirements of the design engineer’s specific application. The type of fan employed also affects the amount of noise generated. The two primary types of industrial fans are axial and centrifugal, and they vary when it comes to noise.

Axial fans work similarly to an airplane propeller, and while they tend to be compact, inexpensive, and light, they are noisier than centrifugal fans. When noise is a concern, alterations can be made to fans, and these include insulation of the duct, installing material that dampens sound, or mounting the fan using soft materials such as rubber.

操作风扇时，一些噪音将是不可避免的，但某些风扇类型，安装选项和设计可以尽可能最大限度地减少噪声。

Many Determining Factors

For buyers and designers in the market for cooling systems, the above factors represent some of the major concerns associated with acquiring fans. There are other aspects to consider as well. The exact sources of heat, fan performance, reliability, and cost all need to be taken into account.

When determined early in the system design process, the correct cooling system will help keep hardware and personnel safe while increasing the longevity of important equipment. By acquiring high quality cooling fans, buyers and designers can easily ensure that even the most advanced, dense, and heat generating equipment can be operated with the utmost safety and efficiency.

Automation is now a buzz word and hot technology trend in both the consumer and manufacturing worlds, so it is interesting to consider how various motion controls would work in a fully integrated and automated society.

To what degree could every aspect of a home’s HVAC and appliances be operated via intelligent controls, and to what extent could a manufacturing environment be controlled by smart automation?

智能运动控制直流电刷的使用金宝搏188bet官网less fans and blowers has already arrived. With Intelligent Motion Controls, the movement of air is now smarter.

毫无疑问，包含全波路电路设计和多种功能毫无疑问，智能增强了空气运动。

A few Intelligent Motion Control features for DC brushless fans and blowers include:

• Inrush Current Protection– Allows the power to be turned on to supply current to the fan. The current begins at zero and gradually increases until the fan reaches its maximum speed and rated current.
• 自动启动– An intelligent motion control ensures that if a fan’s blade is blocked and released, the fan will automatically restart.
• DC Voltage Signal Control– The DC Voltage Signal Control (VPWM) controls the speed by applying an external DC voltage signal.
• 自动温度控制– When the Automatic Temperature Control is applied, the upper and lower temperatures may be selected, as well as the choice of maintaining a minimum RPM below the minimum temperature chosen.
