An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source. The auto transfer switch has advantages of simple structure, easy & reliable operation, no noise, small impact, and long service life. Auto changeover switch is suitable for the illuminating circuits of commercial buildings, shopping mall, banks, and high-rise buildings where the power supply can not be cut off for a long time.

A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller's vane tips.

An induction motor refers to an AC motor that relies on electromagnetic induction between the stator and the rotor to induce a current in the rotor to realize electromechanical energy conversion. The stator of the induction motor consists of three parts: the stator core, the stator winding and the frame. Under normal circumstances, the rotor speed of the induction motor is always slightly lower or slightly higher than the speed of the rotating magnetic field, so it is also called an "asynchronous motor".

Its advantages are fast speed, high precision, large range, strong anti-light and electrical interference ability, etc. And it can realize non-contact long-distance measurement.

The electrical measuring instrument in the pressure measuring instrument is usually called a pressure transducer (pressuretransducer). It is a sensor that converts the pressure signal into a voltage signal output. Usually the pressure sensor is generally composed of elastic sensing element and displacement sensing element. The function of the elastic sensing element is to make the measured pressure act on a certain area and convert it into displacement or strain, and then the displacement sensing element or strain gauge converts it into an electrical signal that has a certain relationship with the pressure. Sometimes the functions of these two elements are combined. 

Static eliminators are products that protect susceptible items from the effects of static discharge. These static shields are also known as antistatic (anti-static) devices, anti-static electricity devices, or static charge eliminators. Static eliminators work by dampening, reducing, or otherwise inhibiting its buildup or discharge.

Today we will introduce what is a voltage sensor and its working principle and function. We hope that after reading this article, you will have a clearer understanding of voltage sensors.

A voltage sensor is a sensor that senses the voltage being measured and converts it into a usable output signal. In various automatic detection and control systems, voltage sensors, often need to track and collect high-speed changing AC and DC voltage signals.

Butterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. Butterfly valve can be used for switch control of low-pressure pipeline medium. It means that the closing member (disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing of a valve. Today, we are going to introduce what is a butterfly valve to you. We hope that you can have a general idea about it after reading.

Hybrid stepper motor is a stepper motor designed by combining the advantages of permanent magnet and reactive. It is divided into 2 phase, 3 phase and 5 phase. The two phase stepping angle is generally 1.8 degrees, the three phase stepping angle is generally 1.2 degrees, and the five phase stepping angle is generally 0.72 degrees.

Centrifugal pumps are widely used in electric power production, because of their wide range of performance (including flow, pressure head and loss of media properties), small size, simple structure, easy operation, uniform flow, long life, Prominent advantages such as lower acquisition costs and lower operating costs.

Servo motors are mainly classified into DC servo motors and AC servo motors. DC servo motors are divided into brush and brushless motors. Brushed motors have low cost, simple structure, large starting torque, wide speed range, easy to control and maintain (changing carbon brushes), it will generate electromagnetic interference and have specific requirements for the environment. Therefore, it is suitable for common industrial and civil occasions that are sensitive to cost.

The brushless servo motor is small in size, light in weight, large in output, fast in response, high in speed, small inertia, smooth in rotation, and stable in torque. The control is complex and easy to realize intelligence, and its electronic commutation method is flexible, and it can be square wave commutation or sine wave commutation. The motor is maintenance-free, highly efficient, low operating temperature, low electromagnetic radiation, long life, and can be used in various environments.

Gear motor is an integrated device of speed reducer and electric motor, also known as gear reduction motor. Professional manufacturers integrate and assemble the gearbox and electric motor to be a set for sale. Gear motor is a unit for connection, transmission, speed reduction, and increasing torque. AC/DC gear motors have the advantages of low energy consumption, superior performance, small size, compact structure, reliable and durable, etc.

According to speed, a motor itself can be divided into low speed (low rpm) motor and high speed (high rpm) motor. According to functions, there are drive motors and control motors. No matter what kind of motor, there is a rated speed and torque. To obtain variable speed, a dedicated controller or speed regulator is needed to control the speed, but this will increase a certain cost and cause the motor price to become higher. On the other hand, performance of the motor after speed regulation will decrease to varying degrees. In this case, gear motor can perfectly solve this problem.

During the operation of the air compressor, if the motor is always easy to be burned, and after the winding is burned, some phenomena or direct causes that caused the burn are covered, making post-mortem analysis and cause investigation more difficult, often making users confused and anxious.
