I believe that everyone is no stranger to the use of variable frequency motor, in order to ensure that everything goes smoothly when we work, we should pay attention to some problems when choosing the motor, otherwise it will be too late to regret, how should we choose when choosing? Let's take a look at the introduction of Xiaobian. 1. The choice of the type of our factory motor type, on the one hand, according to the requirements of consumer machinery for the mechanical characteristics of the motor, starter energy, speed regulation performance, braking preparation, overload ability, etc.; In addition, on the one hand, it is also necessary to reduce the initial investment, reduce operating expenses and other economic aspects of comprehensive differentiation. Under the condition that there is no extraordinary request for performance such as starting and reading speed, the three-phase asynchronous cage motor is preferred. 2. Power selection When selecting the power of the motor, the sel

Ultra-high efficiency three-phase asynchronous motor is the main product of our Shandong Kaiyuan Motor Co., LTD., because of its excellent use effect has been recognized and welcomed by the majority of customers, recently there are customers to consult us to turn to how to change the way, we now tell you in detail, together to understand. Kaiyuan told everyone that the newly made motor, when the winding phase sequence U, V, W and the phase sequence of the power supply A, B, C are the same, after the power is turned on, the motor should be turned clockwise by the motor shaft extension. If the motor steering is opposite to the direction required by the drive, as long as any two-phase power line is replaced, the rotation of the magnetic field will be reversed, and the motor steering will be changed. What is to be discussed here is whether it is possible to change the winding joint to change the steering of the motor? The answer is yes.

The use of three-phase asynchronous motor should be familiar to everyone, we will use its power speed calculation method when we use it, which will improve our work efficiency, but some users are not very clear, we as a professional manufacturer to tell you now, take a look. The motor is an ordinary three-phase asynchronous motor, Y-type connection. Rated voltage -380V, rated power 7.5KW, rated current 15.2A. Through experience, the total power of the three-phase motor is equal to 3 times the power of each phase, that is, p=3*u*i, where: p is the total power of the three-phase motor, unit watt u is the phase voltage, unit volt i is the phase current, unit amperage note: It is also known that the line voltage is equal to 1.732 times the phase voltage, and the line current is equal to the phase current, that is, p=3* (U/1.732) *I

The use of the motor is an essential product in the machine, we can also make full use of its advantages when using, and the price is not cheap, so we need to maintain its life when using, then what can we do to extend its life? Xiaobian organized the relevant information, let's have a look. 1, Kaiyuan told you to first clean the high voltage motor. Remove the dust and sludge from the outside of the high voltage motor frame in time. If the use of environmental dust more, it is best to clean once a day. 2, check and clean the high-voltage motor terminal. Check whether the wiring screws of the junction box are loose or burned. 3, check the fixed part of the screws, including anchor screws, end cap screws, bearing cap screws, etc. Tighten the loose nut. 4, check the transmission device, check the pulley

The use of three-phase asynchronous motor believe that everyone is no stranger, we should pay attention to check the lubrication when using, so that it will not affect our use, then how to check the lubrication will not make mistakes? Xiaobian collated the relevant information, everyone to understand. Three-phase asynchronous motor maintenance Check the appearance of the motor for cracks, whether the fastening screws and parts are complete, and whether the fixed situation is good. Turn the motor shaft to check whether the rotor can rotate freely and whether there is noise when rotating. According to the data shown, such as voltage, power, frequency, connection, speed, etc. are consistent with the power supply and load. Check whether the work of the motor transmission mechanism is reliable. High voltage motor maintenance needs to check whether the ventilation of the motor and bearing lubrication is normal.

Three-phase asynchronous motor in the use of is very convenient, it also because of its own advantages have been recognized by everyone, but the machine in the use of a long time after the failure, so it will affect our use, then in this case how do we fault? Xiaobian collated the relevant information, a look. Winding is a part of the motor, aging, moisture, heat, erosion, foreign body intrusion, external impact will cause damage to the winding, motor overload, undervoltage, overvoltage, lack of phase operation can also cause winding failure. Winding fault is generally divided into winding grounding, short circuit, open circuit, wiring error. The fault phenomena, causes and inspection methods are described respectively. Winding grounding refers to the winding and the core or the shell insulation damage caused by

Electric motor, a device that converts electrical energy into mechanical energy. The old commonly known as Motor, is the transliteration of motor. The circuit is represented by the letter "M" (the old standard was "D"). [1] In 1821, Faraday invented the first electric motor, the first device to use current to move objects, relatively simple. In 1873, the Belgian Gram invented the high-power motor, and the motor began to be used in large-scale industrial production. The prototype of the DC motor appeared in the 1830s. Due to the inherent shortcomings of the DC motor itself (mainly the commutation problem, especially in the case of high voltage), after the 1880s, AC motors have been rapidly developed. The production of electric motors in China began in 1917. The concept of the motor motor: according to the law of electromagnetic induction to achieve the conversion or transmission of electrical energy an electromagnetic device

Motor: also known as motor (commonly known as motor), refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main role is to produce driving torque, as a power source for electrical appliances or various machinery. The impetus for the widespread use of electric motors comes from the advent of the direct current motor, which was invented by Belgian engineer Gram in 1870 and produced in large quantities, and then continued to improve the efficiency of the motor. Siemens of Germany, another research unit in electric motors, is also working hard. At about the same time as Gram's success, Siemens introduced the electric locomotive, which does not burn oil, to much acclaim at the Berlin Industrial exhibition. The invention of the AC motor was completed by the American inventor Tesla, the earliest AC electric
