Stepping Motors Drive New Smart Faucets

智能设备在我们家里正在激增es, but the last device you might expect to become intelligent is the faucet. The reality is though, a smart faucet can save money by reducing water and energy consumption. You can use it hands-free and adjust the flow to suit what you’re doing. It can even prevent scalding by water that’s too hot!

智能水龙头依赖linear steppingmotors用于可靠且可重复的操作。这是关于他们的更多信息。

需要更好的流量控制

随着干旱变得越来越普遍，水的价格不断上涨，保护越来越重要。减少消耗的一种方法是仅使用您需要的东西而不是让水龙头运行。有时，尽管您可能会饱满并且无法将其关闭。

When you need hot water, mixing and adjusting for the optimal temperature causes more waste. It’s easy to run the water hotter than needed, which wastes energy and can be dangerous if it causes scalds. Many times someone might just want to reduce the volume of water flowing. An example is varying the flow of water in a shower from intense massaging jets to a sensation of light rain.

由于所有这些原因，显然需要更好地控制智能水龙头操作。

Stepping Motors for Flow Control

水龙头是一种阀门。他们可能管理一个流，热或冷的流的流动，或者可以控制混合和流动。通过移动塞子或门以阻塞流来控制流。在传统的水龙头中，当您转动杠杆或旋钮时，就会发生这种情况。在智能水龙头中，该运动是由垫脚电机提供的。

Stepping motors use the magnetic field generated in the coil windings to push and pull permanent magnets on the shaft or rotor. Switching current flow reverses the polarity and drives rotation.

永久磁铁（PM）步进电动机use electronics to rotate the shaft through a number of steps determined by the controller. This rotation can be turned into linear motion, as is done in linear stepping motors like the PL25L from MinebeaMitsumi.PM步进电动机这样，提供精确且可重复的线性运动，而无需用于闭环控制的反馈系统的费用和复杂性。

Using PM Stepping Motors In Smart Faucets

In contrast to a solenoid-operated valve, which is either open or closed, a smart faucet operated by a stepping motor provides precise control over open area, thereby regulating flow.

这intelligent faucets on the market today are operated by touch, gesture or through a “smart” assistant such as Alexa. All these methods give users a noncontact way of starting and stopping the flow. They can increase or reduce the flow rate as requested, and they can shut off after a preset time.

温度控制是通过管理热水与冷的比率，再次通过踏脚电机打开和关闭内部通道来实现。一些智能水龙头让用户指定所需的精确温度并调整流程以维护它。

智能水龙头的好处

对流动提供的精确控制线性步进电动机improves comfort and convenience, but it can also lead to measurable savings. Setting an upper flow limit could reduce consumption while a timer function avoids the waste from water being left running, (perhaps while someone working in a kitchen had their hands full or another task to perform.) And think of the savings from controlling how long a shower runs!

Temperature control leads to more savings. Using less hot water saves the energy required to heat it. In addition, water consumption is lower, leading to reductions in the water bill!

使用NMB步进器升级产品功能

线性PM步进电动机are a cost-effective way of achieving precise, repeatable positioning. Smart faucets are an excellent application because their use saves water and energy while improving comfort and convenience. NMB Technologies Corp, part of the MinebeaMitsumi Group, offers an extensive range of stepping motors and other electrical devices that provide and control rotary motion.
