Bearings are essential components in mechanical design and industrial manufacturing. Although they are small in size, they play a key role in transmission systems. Today we are going to talk about two common but very different types of bearings: Deep Groove Ball Bearings and Linear Ball Bearings. Although they both contain "Ball Bearings" in their names, they are very different in structure, function and usage scenarios. Understanding their differences will help engineers and designers make appropriate selections for different projects.

Density meter is an important instrument used to measure the mass per unit volume of a substance. It is widely used in petrochemical, food and beverage, pharmaceutical, metallurgy, material research and other fields. Due to different application scenarios and measurement objects, there are many types of density meters, which can easily confuse people when selecting. ATO will systematically classify density meters from three dimensions: usage scenarios, measurement media and working principles, and illustrate them with typical examples to help everyone quickly understand the characteristics and uses of various types of density meters.

A fire pump is a specialized device used to increase the pressure and flow rate of water in a fire protection system, such as a sprinkler system or standpipe system, to ensure an adequate water supply in the event of a fire. Fire pumps are designed to deliver large quantities of water at high pressures and are often installed in commercial or industrial buildings as well as in high-rise residential buildings.

An absolute encoder is a detector that outputs angular data to an external target within one revolution of the motor. Absolute encoders are typically capable of 360° output in 8 to 16 bits. ATO.com online store offers single-turn absolute encoders and multi-turn absolute rotary encoders for you to choose from, offering 10-bit/12-bit/14-bit rotary encoders. Below is a price list of some of the absolute encoders in our store for your reference.

A desoldering pump, also known as a solder sucker or tin suckers, is a hand or power tool widely used in electronic repair and assembly, mainly for removing excess solder from circuit boards and helping technicians safely remove electronic components. The desoldering pump is commonly used to repair old circuit boards, replace faulty components, reinstall soldered parts, or perform tin removal cleaning of circuit boards, and is one of the indispensable tools for electronic engineers, repairers, and DIY enthusiasts.

In the previous article, we explored how to control a BLDC (Brushless DC) motor using the I/O+SV control method. In this article, we will introduce another efficient approach: I/O+RV control.

The I/O + SV method can efficiently control the speed and direction of the BLDC motor. This method controls the start and stop and direction of the motor through input signals, and adjusts the speed through variable voltage. In this guide, ATO online store will guide you on how to create a BLDC (brushless DC) motor controller circuit using the input/output (I/O) + speed voltage (SV) control method.

Origin point return control is the control process in the automation system that makes the motion axis return to the preset mechanical origin. It is a standard operation when industrial automation equipment is started or reset. Realizing this function through the cooperation of HMI and PLC is a typical application in industrial automation. Today, ATO Automation will walk you through the complete setup process, from component introduction to system testing.

Pulse Width Modulation, or PWM, is a modulation technique that varies the width of the pulse in a periodic waveform while keeping a constant frequency. It involves repeatedly turning a signal on and off, with the width of each pulse representing the signal's amplitude. By adjusting the pulse width, PWM allows for precise control of the average power delivered to a load.

Stepper motors are widely used in precision applications due to their accuracy and reliability. However, like any complex machinery, they can face issues that affect their performance. In this article, we'll explore common stepper motor problems and provide practical troubleshooting tips to help you keep your systems running smoothly.

Check valves are an important fluid control device that is widely used in industrial piping systems to prevent backflow of media, protect equipment safety, and ensure stable system operation. Whether in water supply systems, petrochemical pipelines, or other liquid or gas transportation processes, choosing the right check valve is crucial. This post will introduce you to the various check valve types and their price ranges on ATO.com to help you find the best solution.

A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by overloads or short circuits. It works by automatically interrupting the flow of current when it detects an issue, preventing damage to the wiring and reducing the risk of fire or further equipment failure. Have you ever wondered what the letters in circuit breaker abbreviations stand for? Let's delve into the meanings behind these abbreviations and the types of circuit breakers they represent.

In industrial operations, ensuring the smooth functioning of electrical equipment is paramount. One of the critical components in this effort is the phase monitoring relay. In this post, let's explore how this relay functions and why it is vital for maintaining the integrity of electrical systems.

A power divider, also known as a power combiner and splitter, is a passive multi-port network that is widely used in microwave circuits. Its main function is to evenly distribute an input signal to multiple output ports, or to combine multiple signals into one output signal. A power divider plays the role of signal distribution, signal synthesis and power balancing in a radio frequency (RF) system.

In industrial automation, communication between a Programmable Logic Controller (PLC) and a Variable Frequency Drive (VFD) is essential for controlling motors and adjusting their speed, torque, and other parameters. Here are the general communication types between a PLC and a VFD.

In many cases, we may need to run three-phase motors on a single-phase power source, especially in residential or small industrial environments without a three-phase power source. Although three-phase motors are more efficient and powerful, simply making some changes to the wiring and adding the correct components can make them suitable for single-phase 220V power supply. In this guide, ATO online store will guide you through the necessary steps to convert a three-phase motor to a single-phase power source for operation.

There are many types of gas detectors, each developed to detect and monitor one or more gases at potentially dangerous levels. Today, ATO will explore different types of gas detectors based on various criteria to help you choose the most suitable option for your specific needs.

Glass lined reactor is an important equipment for handling chemicals, and is widely evaluated in the chemical, pharmaceutical, food and other industries. Its interior is coated with corrosion-resistant glass lining, which can effectively prevent the reactants from contacting with the reactor. In addition to the traditional glass-lined reactor, there are several different types of glass reactors, such as single-layer glass reactors and jacketed glass reactors. These types of reactors have their own characteristics and are suitable for different reaction needs.

When converting a three-phase induction motor into a generator, correctly sizing the capacitors is crucial to ensure efficient operation. Capacitors are used to offset the inductive characteristics of the motor, improving its power factor and overall efficiency. If you're wondering, “What size capacitor should I use?”, this guide will walk you through the process of determining the correct capacitor size for your generator conversion project. In this tutorial, ATO industrial automation will explain what ‘capacitor size’ implies and provide you with all necessary formulas and important considerations you would need to figure it out yourself.
