Temperature protection refers to the overheating phenomenon of three-phase asynchronous motor when the current does not exceed the rated value, because of environmental factors, frequent startup times and other reasons. In this case, neither overcurrent protection nor overload protection can solve the problem, so thermal protectors that reflect temperature changes are needed.

Phase off protection refers to the three-phase asynchronous motor in normal operation, any power supply suddenly disconnected, at this time the motor is in phase off operation. Today, Senli Motor Xiaobian will understand the phase break protection of the next three-phase asynchronous motor with you.

The rotor part of the motor product is supported by two sets of bearings, and the torque motor rotor is positioned in radial and axial direction relative to the stator. Today, Senli Motor Xiaobian will discuss with you the small knowledge about bearing maintenance.

Shengzhou Senli Motor is a torque motor manufacturer, our products from 63 stand to 112 stand, according to different running speed requirements, made of 2,4,6,8,10 poles, forming a variety of torque motor series products, up to 20N.m torque. What are the effects of different pole choices on device applications? Today we will understand together!

The frequency conversion energy-saving motor products produced by Senli motor reduce energy efficiency by 5%. According to customer requirements to provide more energy-saving inverter motor, DC motor, energy efficiency motor. Today, follow the three-phase asynchronous motor manufacturers to understand whether the three-phase asynchronous variable frequency motor can really save electricity? For the speed range is relatively large, if the frequency conversion motor is used, the inverter can indeed save power. Because the frequency converter technology is used to drive, the speed can be adjusted within a certain range, and the frequency can be automatically changed, so that the electric frequency can be reduced.

In production, the three-phase asynchronous motor will be damp due to environmental factors, resulting in a decrease in insulation resistance, affecting the normal operation. Today, Senli Motor Xiaobian will take you to look at the drying treatment method of squirrel-cage three-phase asynchronous motor.

Shengzhou Senli motor mainly produces DC motor, torque motor, three-phase asynchronous motor and other products, own engraving machine, wire cutting machine, can provide rapid proofing services, each batch of products can provide a complete test report. In order to meet the needs of customers, we provide a customized, multi-to-one service.

If the current is too high in the motor, in addition to the power supply, load and other problems, there is also a certain relationship with the three-phase torque motor itself, today, Senli Motor Xiaobian will take you to understand the reason why the current is too high because of the motor itself.

Senli three-phase asynchronous motor manufacturers remind that the ordinary three-phase asynchronous motor is designed according to constant power, constant frequency, constant torque, if the operating frequency does not match the rated power, then it will cause the motor heat, weakness and other phenomena, thus affecting normal production.

Three-phase squirrel-cage asynchronous motor, that is, three-phase asynchronous motor, its connection method can be divided into Y-type connection and triangle connection, the advantages of different wiring methods will be different, today, Senli motor editor will take you to understand about its connection method.
