Chain hoists are divided into air chain hoist and electric chain hoist. Air operated chain hoist is a lifting device that uses compressed air as a power source to drive internal mechanical parts to lift and heavy loads. It is composed of a lifting mechanism, a walking mechanism and a gas distribution system. Pneumatic chain block hoist has the characteristics of high frequency, infinitely variable speed and safety. Electric chain hoist is a special lifting equipment powered 3 phase full copper motor to move heavy loads.

The position control mode of the servo motor is very common in the precision movement of industrial automation. The principle is that the servo motor drive carries out precise control of the motor movement after receiving the position pulse and direction pulse of the pulse generator (PLC, single chip microcomputer). Servo motor has three control modes: speed control, position control and torque control. This time we will introduce the position control mode of ATO new servo motor, using PLC to pulse.

There are three commonly used non-contact liquid level sensors, namely capacitive liquid level sensors, ultrasonic liquid level sensors, and separate photoelectric liquid level sensors. The non-contact liquid level sensor can detect the liquid level without contacting the liquid. With this advantage, the application field of the non-contact liquid level sensor has been greatly expanded. The common feature of these three types of non-contact liquid level sensors is that they are not affected by liquid color, corrosiveness, pressure, density, etc., and because the sensor does not directly contact the liquid, it is more hygienic, and it is convenient for users to clean the container, add liquid, etc.

Servo motor can control speed, position accuracy is very accurate. It can convert voltage signals into torque and speed to drive control objects. Servo motor rotor speed is controlled by the input signal, and can respond quickly, in the automatic control system, used as an executive element, and has the characteristics of mechanical and electrical time constant is small, high linearity, can receive the electrical signal into the motor shaft angular displacement or angular velocity output.

Temperature controllers are very common field display instruments and are used in various industrial occasions. Our Dual Channel PID Temperature Controller has an RS485 interface, which can transmit temperature control information to the upper computer through the Modbus RTU protocol for unified information management.

In this blog, we are gonna explain how to connect a Pt100 sensor to the PID temperature controller. To let this happen, we'll use a humidity sensor, a solid state relay and a conventional relay as well as the Pt100 sensor. Follow us to learn the detailed steps.

In addition to the brushless DC motor is often used in industrial automation, we often see its application in electric vehicles. And what we want to introduce today is an infrastructure that it uses in electric vehicles.

The Pt100 temperature sensor is an instrument that converts a temperature variable into a transmittable, standardized output signal. Pt100 is a platinum thermal resistor, and its resistance will change with temperature. 100 after Pt means that its resistance value is 100 ohms at 0°C, and its resistance value is about 138.5 ohms at 100°C. Mainly used for the measurement and control of industrial process temperature parameters. Its working principle is that when the PT100 is at 0 degrees Celsius, its resistance value is 100 ohms, and its resistance value will increase approximately uniformly as the temperature rises. But the relationship between them is not a simple proportional relationship, but should be closer to a parabola.

To let ATO BLDC motor drive fully perform its speed control function, it is very important for you to make sure that the hall sensor is properly connected to the driver. In this blog we’re gonna illustrate the correct wiring steps.

The analog signals used in the industrial control process are generally standardized, such as 0~10V, 0~20mA, 4~20mA, etc., which can greatly solve the problem of signal compatibility, and also provide equipment for the expansion of use. Convenience. Our VFD also supports analog signal input control. Let me introduce the use of 4-20mA to control the frequency of the VFD.

Variable frequency drive (VFD) is an electric power control equipment that uses frequency conversion technology and micro-electronic technology to control ac motors by changing the frequency of the motor's working power supply. Variable frequency drive by internal IGBT off to adjust the voltage and frequency of the output power supply, according to the actual needs of the motor to provide the required power supply voltage, so as to achieve the purpose of energy saving, speed regulation.

A stepper motor is an actuator that converts electrical pulses into angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, and its rotation runs step by step at a fixed angle. The angular displacement can be controlled by controlling the number of issued pulses, so as to achieve the purpose of controlling the displacement. At the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation. The rotor inside the servo motor is a permanent magnet.

Brushless DC motor is composed of motor body and driver, which is a typical mechatronics product. High speed brushless motor refers to the motor without brush and commutator (collector ring), also known as the motor without commutator. Brushless DC motor is widely used in automobiles, tools, industrial control, automation and so on. We also need to know how to use it. Taking ATO's brushless DC motor as an example, this paper describes how to use external switch button to reverse rotation, stop the motor, and external potentiometer to speed the brushless DC motor.

Variable frequency drive (VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. The VFD adjusts the voltage and frequency of the output power supply by switching on and off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation.

Toggle switch as a common manual control switch can be divided into according to the installation mode, panel installation, PC circuit board installation, according to the lamp without lamp. According to the number of poles, there are unipolar, bipolar, tripolar, quadrupole, self-reset and maintenance, large and ultra-small, waterproof, high and low temperature resistance, etc.

DIP switch, short for dual in-line package switch, is an electrical switch that can be turned by hand. Its pitch includes 2.54mm and 1.27mm. There are two pins on the back of each position, all on ON side, which is turned on, and then disconnect. These pins are independent and there is no association with each other. Such products are mostly used for binary coding.

The power system requires a high degree of reliability. During operation, the system may have some abnormal conditions or may cause troublesome problems. Some of these situations are beyond human control and cannot be avoided. Therefore, there is a need for an efficient device to detect such failure conditions and react immediately to minimize damage to the device. Molded case circuit breakers (MCCBs) can help protect equipment. A molded case circuit breaker (MCCB) is a device that protects low-voltage power distribution systems from overloads and short circuits. Molded case circuit breakers allow quick reactivation of a circuit after clearing a short circuit or overload. MCCBs (molded case circuit breakers) can easily identify the difference between an overcurrent and a short circuit. It allows a slight overcurrent for a while, but turns on faster as the current level increases. MCCB can be used to complete protection and disconnection functions.

The speed control methods of the BLDC motor controller include self-contained potentiometer speed control, external potentiometer speed control, and external analog signal speed control (0 ~ 5V). Different occasions and distances can use different speed control mode, which is one of the features of our brushless DC motor kit. Now what we want to introduce is how to use the 5V analog signal to control the speed of the DC brushless motor.

A circuit breaker is essentially a safety device for any property that uses electricity. These fixtures act as third parties in complex and dangerous electrical wiring systems. MCB and MCCB are circuit breakers. They are used in homes to prevent personal injury and electrical damage. These devices are designed to perform specific functions. It is their special features that make them special. So, what are the differences between them?
