The phenomenon of interturn short circuit in three-phase asynchronous motor may be caused by insulation aging or moisture, so how to determine whether the motor is really interturn short circuit? Today, Senli Motor Xiaobian will take you to understand.
Details >
There are many reasons for the short-circuit of the winding of the three-phase asynchronous motor, such as overload, too much current, single-phase operation, production or maintenance process will cause its short-circuit fault; Today, Senli Motor Xiaobian will take you to understand the treatment method of short circuit in motor winding.
Details >
Under normal circumstances, the selected three-phase asynchronous motor is run by extra speed, but if the speed is low, then the slip will increase, the current induced in the rotor increases, the current in the stator will also increase, which will cause the motor overheating phenomenon, which is one of the reasons why the motor can not start.

The motor winding short-circuit fault is a short-circuit phenomenon formed between winding turns or an insulation damage between different winding. After this phenomenon occurs in the three-phase asynchronous motor, the three-phase current unbalance, noise and vibration will occur. Senli Motor Xiaobian will take you to understand the inspection method of short circuit fault in the lower winding.

In the production process, the three-phase asynchronous motor bearing heating phenomenon will be encountered, but if the analysis is not clear or the treatment is not timely, the adoption of measures is not appropriate, it is easy to eat the bearing burn accident; Overheating can be said to be the culprit of bearing failure. Senli Motor Xiaobian will take you to a simple understanding of the reasons for bearing overtemperature.

Bearing overtemperature and dust and pollution also have a great relationship, in some products such as three-phase asynchronous motors in the use of environmental requirements of the equipment, if the air dust particles into the bearing, will produce a variety of hazards, lubrication is also one of the conditions to ensure the normal operation of the bearing, today's three-phase asynchronous motor manufacturers Senli motor will take you to a simple understanding.

Some of the common heating causes of the motor talk a lot, such as the air gap is too large, the power supply voltage is high, the rotor dynamic balance is not good, the bearing is lack of lubricity and other reasons, will cause the torque motor and other products to heat during operation, these are because of the phenomenon caused by the electrical failure of the machine. Today, Senli Motor Xiaobian will take you to understand the causes of heat caused by non-machine electrical faults.

When selecting three-phase asynchronous motors, torque motors, brake motors, etc., it is important to consider the torque required by the load; For example, some mechanical equipment is no-load start, but some are load start, then the demand torque of the latter will be much larger; The following Senli motor Xiaobian will take you to understand the next.

In the selection of motors, a question often asked by motor manufacturers is: how many stages are needed, or how much speed? So what's the connection between the two? Today, Senli Motor, a three-phase asynchronous motor manufacturer, will take you to understand the motor series.
Details >
There are many reasons for the motor to heat, but almost more than half of the motor heat and burn are caused by the motor's lack of phase operation, half of the three-phase asynchronous motors and torque motors that have a lack of phase can not run or the speed is slow after starting, or the rotation is weak, and the current increases will make a "buzz" sound.

Long axis torque motor products, suitable for winding and winding scenarios, can be customized for different industry scenarios, to meet the requirements of use. This product produced by Senli has the characteristics of reasonable structure, high efficiency, good characteristics and long service life.
Shengzhou Senli Motor19Old motor manufacturers, with a number of their own motor production lines, from the shell, shaft, rotor, stator are independent production, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports. From the shaft machining to the whole machine assembly are completed independently. Truly realize factory direct sales.
Senli motor products are used180°High temperature resistance all copper coil material, torque motor products can be used with different rotors (ordinary rotors/Steel rotor), rotor of different motor characteristics are different, we from the shell, shaft, rotor, stator are produced by the independent, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports.
