In industrial applications such as automation technology, servo motor is the most commonly used high-tech equipment. Servo motor can control speed and position accuracy, also can convert voltage signals into torque and speed to drive control objects. Servo motor is divided into AC servo and DC servo two categories.

Laser distance sensor is a kind of sensor which uses laser technology to measure the distance. It is generally composed of laser, optical parts and photoelectric devices. It can convert the measured physical distance into optical signals, and then use photoelectric converter to convert the optical signals into electrical signals. Through the filtering, amplification and rectification of corresponding circuits, the output signals can be obtained, so as to calculate the measured quantity.

In the servo system, the engine that controls the operation of mechanical components is called servo motor, which is a kind of subsidized motor indirect variable speed device that can control the speed, so that the position of the object and the orientation, state and other output controlled quantities can follow the input target (or a given value) of any change, and the position accuracy of the servo motor is very high, and it can convert the voltage signal into torque and speed to drive the control object, but how does a servo motor control work?

No matter what kind of servo motor, use for a long time, will produce some small problems, then today we bring you six common motor failure performances. When the servo motor has small problems, not only to detect promptly, but also to find the cause of these failures, we can prescribe the right medicine to repair the servo motor.

Servo motor is an independent electrical device, which can rotate each part of the machine with high efficiency and precision. The output shaft of this motor can be moved to a specific angle, position, and velocity that a normal motor does not have. Servo motor adopts conventional motor and its position feedback with the sensor. Before using the servo motor, you need to know how to use it to better play its role.

If the cable drag chain cable is stretched by tension during wiring, it will friction with the inner wall of the drag chain and cause the sheath to wear. On the contrary, if the wiring is too loose, it will also cause friction with the inner wall of the drag chain, causing the sheath to wear, and it will easily be entangled with other cables. The wiring length of the drag chain cable should be set to just pass the center line of the drag chain. In addition, if the moving part of the drag chain cable is fixed, the bending stress will not be dispersed and absorbed. The fixed part of the cable should be set at both ends of the drag chain.

First of all, in terms of flexibility, drag chains are more flexible than ordinary cables. Although the monofilament diameter of the drag chain cable conductor is small, in order to protect the conductor, an insulating material with resistance to mechanical fatigue and a certain strength must be selected. The requirements of tensile resistance, bending resistance, strong wear resistance, anti-blocking, and high toughness also determine that the protective cover material should also have a certain degree of hardness. Therefore, the flexibility of the drag chain is high flexibility, not high flexibility.

Impact wrench principle can be said to be "accomplish a great task with little effort by clever maneuvers", so it is commonly recognized and used in large-scale assembly and maintenance. However, impact wrenches are tools after all, and after long working hours or regular use, they will be damaged to different degrees, which requires us to have professional knowledge of repair and maintenance of wrenches.

A variable speed motor is a motor that has a variable frequency drive or similar technology installed to control motor speed and torque, by placing these key factors of motor performance under the control of the operator, variable speed motors offer a means for products and production facilities to greatly reduce the amount of energy being consumed by the motors in their devices. Unlike single-speed motors that run at full capacity and then cycle off, a variable-speed motor can operate at high speeds, low speeds or anywhere in between, ramping up and down like a dimmer switch. Variable speed motors are widely used in places that require energy-saving continuous operation and frequent work, such as fans, air compressors, injection molding machines, reducers, water pumps, vacuum pumps, etc.

In the automated production process, liquid level detection and monitoring has always played a more important role, such as the production of food and beverage, daily chemical products, pharmaceuticals, semiconductors and other industries, the cooling and lubrication of various machines, liquid level monitoring directly affects the quality of the product, and even related to the production process can be carried out smoothly.

The main function of a time relay is to act as an actuator in a simple program control, when it receives a start signal to start the timing, after the timing is over its operating contacts are opened or closed, thus driving the subsequent circuit work. Generally speaking, the time delay performance of a time relay is adjustable within the design range, thus making it easy to adjust the length of its delay time, so this article will tell you how to adjust time relay.

The current sensor converts a large current into a small current with the same frequency and phase to facilitate measurement or isolation. According to different transformation principles, current sensors generally have five technologies: Hall effect, fluxgate, electromagnetic induction, Rogowski coil (the principle of electromagnetic induction and Ampere’s loop law), and shunt (Ohm’s theorem). This article is to introduce the features of ATO current sensors and their prices.

A pressure sensor is normally used to determine the value of the pressure generated in a system. The main intention is to compare to expected values for expected safe operation of the system in question.

Common systems where pressure sensors are used include but are not limited to:

• Compressed air systems.
• Lubricant oil systems.
• Water pumping systems.

The systems mentioned above can actually be found in different industries and there are other systems which require pressure sensors. So, let’s see how pressure sensors can be used in each.

The pull rope switch is composed of pull rod, reset handle, cam, lock slot and micro switch. The pull rope switch is installed on the frame on both sides of the belt conveyor, and the switch is connected with the steel wire rope along both sides of the conveyor. When an emergency occurs in the conveyor belt equipment, the wire rope is pulled anywhere along the line at the site, and the wire rope pulls the drive arm to rotate, which drives the torque spring through the drive shaft to displace the precision cam and drive the control line, making the conveyor stop running.

When you are in a factory, refinery, pipeline or any other hazardous work environment there are many different things that need to be monitored and kept at the highest level.  Failure to monitor and treat them can lead to devastating accidents, but with some clever technology, such as gas detectors, so you can make sure you are always aware of any gas that is permeating your workspace thus ensuring safety.
