Motor products are common in the production of electrical equipment, its main role is to convert electrical energy into mechanical energy; Among them, squirrel-cage three-phase asynchronous motor is widely used in modern industrial production, mainly because of its simple structure and convenient start. Small size, easy to maintain and repair, and reliable work.
Details >
For the newly installed or deactivated three-phase asynchronous motor products for more than 3 months, we need to do a check before we can start, the following Shengzhou Senli Motor Xiaobian will share with you, how to check the newly installed asynchronous motor before starting.
Details >
In the previous article, we said that the mechanical failure of the three-phase asynchronous motor is mainly a problem of sweeping, vibration, bearing overheating, etc., has talked about the content of sweeping failure, then the following Senli motor Xiaobian will briefly tell you the next step of motor vibration and bearing failure.

Temperature rise is an important indicator of the motor in the design and operation, marking the degree of heat of the motor, when the heat and heat dissipation of the three-phase asynchronous motor are equal, to reach an equilibrium state, the temperature is no longer rising but stable at a level; However, if the heat of the asynchronous motor increases but the heat dissipation decreases, the balance between the two will be destroyed, and the temperature will rise.
Details >
The last part of Senli motor Xiaobian simply tells you about the insulation materials and temperature rise of the three-phase asynchronous motor, the impact of temperature rise on the life of the asynchronous motor, today we will talk about the impact of environmental temperature and other factors, will cause what kind of damage to the motor.
Details >
Temperature rise is a very important performance index of motor products, the current Senli motor commonly used insulation materials are E, B, H, F, etc., can be customized according to demand, the limit working temperature is 120℃, 130℃, 180℃, 155℃, the limit working temperature of the insulation material refers to the three-phase asynchronous motor product in the design life expectancy, The corresponding temperature value of the hot spot in the winding insulation during operation.
Details >
When we select motor products such as three-phase asynchronous motors and torque motors, motor manufacturers will ask the required speed requirements, this is because the rated speed of the motor should be selected according to the requirements of the equipped production machinery. Today, Senli Motor Xiaobian will take you to understand the choice of motor speed.
Details >
Asynchronous motor overload protection can prevent because the load is too large, resulting in increased equipment damage to a protector, three-phase asynchronous motors have a running power, we call is rated power, if the actual power used in a certain situation exceeds the rated power we are also called overload.
Details >
Overload and short circuit are often mentioned in production, one of the differences between the two is that the overload current will flow through the load, but the short circuit current will not flow through the load, and today the torque motor manufacturer will take you to understand some of the differences between the two
Details >
Protection measures are an indispensable part of the automatic control system, the use of reasonable protection measures can ensure the long-term normal operation of the motor, can avoid some damage caused by failure, and ensure personal safety; So today, Senli Motor Xiaobian will take you to understand what protection measures the next motor has!
Details >
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.
