Locking plug is known as NEMA connectors. NEMA stands for the National Electrical Manufacturers Association, a USA-based organization that forms a set of globally recognized and internationally applied standards for the manufacturing of electrical equipment. These standards outline the voltage and amperage configurations of plugs and receptacles to make it easier for consumers to differentiate them. NEMA connectors, including power plugs and receptacles, are among the electrical product categories covered by NEMA standards.

Modern industrial automated machinery is powered mostly by motors. The torque generated from a rotating motor provides the driving force for moving conveyor belts, gears, chains and other mechanical components, so a motor naturally becomes such an integral part that is key to the driving system. When it comes to the protection of the core power part, you can't pay too much attention to it. Thermal overload relays are used to provide overload protection, open-phase protection and protection against the unbalanced current for motors and they can also avoid heating in electrical equipment. The thermal overload relay works by the thermal effect of electric current to push the action mechanism to make or break contacts for the protection of electrical appliances.

Most people understand that synchronous motors use power to generate motion. Some motors are powered by DC current, others by AC current, others by a combination of the two, and their specific method of energy transfer is unique to each motor. This article will focus on synchronous motor. It aims to explain the definition, features of synchronous motors and differences between induction motor, so that anyone looking to use one of these devices has the relevant information to do so.

The structure of the quick connector can be divided into two-ended open and closed, two-ended open and closed, and single-way open and closed.

An anemometer is an instrument that measures the speed of air. There are many types of it, and the three-cup anemometer is widely used. Robinson in the United Kingdom invented the rotating cup anemometer, and it was four cups at that time, and then it was changed to three cups. The three parabolic or hemispherical empty cups fixed to each other on the rack are all in one direction, and the entire rack together with the wind cup is mounted on a freely rotatable shaft. The three-cup anemometer commonly used in meteorological stations is composed of three parabolic cone empty cups fixed on the bracket at 120° to each other, and the concave surfaces of the empty cups are all in one direction. The entire induction part is installed on a vertical rotating shaft. Under the action of wind, the wind cup rotates around the shaft at speed proportional to the wind speed. Another type of rotary anemometer is the propeller anemometer, which consists of a three-blade or four-blade propeller to form a sensing part, which is installed at the front end of a wind vane so that it is always aligned with the direction of the wind. The blades rotate about the horizontal axis at a speed proportional to the wind speed.

ATO pneumatic grease pump is a kind of refueling equipment, which is widely used at present. It can replace oil in time for automobile maintenance and various mechanical equipment. The pneumatic grease pump with 3 gal~12 gal is the most powerful assistant in production and life. It is a kind of pneumatic tool.

A hydraulic hand pump uses human power as an input to generate a combination of pressure and flow, which then produces hydraulic energy. Based on the simple principle of a handle providing leverage to an internal piston, hydraulic fluid is delivered directly under manually applied pressure. The piston then forces the hydraulic fluid into the cylinder port. Water and hydraulic fluid are the most common fluids, but a variety of pressure media can be used.

Industrial endoscope is a multi-disciplinary universal tool, its function is to bend the pipe deep exploration, can observe the parts that can not be directly observed, can observe the internal space structure and state in the sealed cavity, can realize long distance observation and operation. This article briefly introduces the scope of industrial endoscope.

Magnetic sweepers use the power of magnets to clean, they save you time. These machines are also known as magnetic brooms. You can use this sweeper to collect iron filings and scrap. These brooms are great for pulling any metal and steel parts. To name a few: staples, screws, iron filings, nails, nuts, shavings, pins, metal dust, barbed wire, etc.

Industrial endoscope is a type of visual inspection in non-destructive testing. Without dismantling the detected object, it directly reflects the internal and external surface conditions of the detected object (such as: cracks, burrs, welds, etc. inner surface quality). And at the same time of inspection, we can use industrial endoscope equipment to make dynamic video recording or photographic recording of the entire inspection process, and can quantitatively analyze the defects found.

An infrared temperature sensor is a sensor that uses the physical properties of infrared rays to measure, and only measures the surface temperature. Infrared light is also called infrared light, which includes reflection, refraction, scattering, interference, absorption and other properties. This property of infrared temperature sensor makes it have a wide range of applications.

Star delta starter is a starting device of asynchronous motors. The starting current of induction motors is relatively large during the starting process, so motors with large capacity can use the wye delta starter. The star delta starter is actually a step-down starter. When it starts, the stator winding of the motor is connected into a star shape, and when the speed reaches close to the rated speed, it is changed into a △ to reduce the starting current.

An industrial endoscope refers to an optical device that consists of a hose (flexible or rigid) with a lens at one end and an eyepiece attached to the optical system at the other end. Cameras in industrial endoscopes can produce high-quality images without spending a fortune. The device also comes with lighting and vision systems. The lighting system requires an optical fiber to illuminate the interior of the area.

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. 

BLDC motor (also known as brushless direct current motor) is a kind of permanent magnet synchronous motor. BLDC motor replaces the mechanical commutator on the brushed DC motor with an electric commutator, and is powered by a DC power supply through an integrated inverter or switching power supply to generate an AC signal to drive motor. It has the advantages of simple structure, no sparks during commutation, high operational reliability and low maintenance cost, so it has great advantages over traditional brushed DC motors in performance. BLDC motors have high efficiency and good operability, so they are widely used in various transmission industries.
