Ac servo motor in the process of use，To ensure safe and stable operation，Note the following safety precautions：one、Check before use and prepare for connection check：Before use，All connections of the servo motor should be carefully checked for tightness and correct wiring，Power cord included、Control line，Prevent motor damage or safety accidents caused by poor contact or wrong wiring。Environmental inspection：Check whether the installation environment of the motor meets the requirements，Ensure good ventilation、No corrosive gases and inflammable and explosive materials，To prevent dangerous situations such as overheating or explosion of the motor。Parameter setting：According to equipment requirements and motor performance，Set the servo drive reasonably
Servo motor heating is a common phenomenon，However, too high a temperature will affect the performance and life of the motor。In order to reduce the problem of servo motor heating，The following solutions are possible：one、Optimized heat dissipation structure using efficient heat dissipation materials：Servo motor shell can choose aluminum alloy and other good thermal conductivity materials，To improve heat dissipation efficiency。Increase heat dissipation area：By increasing the area of the radiator，Such as using a large area of heat sink or heat pipe radiator，It accelerates heat dissipation。Replace the high efficiency fan：Select higher speed、A fan with more air，Or use a fan with intelligent controls，The fan is automatically adjusted according to the temperature of the servo motor
The offset detection and adjustment of motor and coupling is an important step to ensure the stable operation of mechanical equipment。The following is a detailed detection adjustment method：one、Offset detection method Traditional method：Tool measurement：The different concentricity of the coupling can be measured using a knife rule and a piston rule，The non-parallelism of the end face of the coupling is measured by wedge gap rail or feeler ruler。This method is suitable for low speed elastic joints、Equipment with low precision requirements。But be warned，This approach may be limited by the field environment and equipment complexity。Wire winding method：Wrap two pieces of wire around the two couplings，Adjust the distance between the wires，And rotate the axis all the way around，observe
In industrial laser cutting machines，Linear guide rail and ball screw are the key components of its high-precision motion system。Each of them performs an important function，Together to ensure the laser cutting machine high precision、High stability and efficiency。Linear guide The linear guide is mainly used to support and guide the moving parts of the laser cutting machine，Enables it to move in a straight line with high precision in a predetermined direction。Linear guide has the following characteristics：High precision：Linear guide rail through precision machining and installation，Ensures high precision positioning of moving parts during movement，Meet the strict requirements of laser cutting accuracy。High rigidity：Linear guide mining
Servo motors play an important role in industrial automation，However, some problems are often encountered during its operation。The following are some common problems of servo motors and their brief descriptions：one、The power supply is faulty：Including voltage instability、The power line is aging or in poor contact，The motor may not start or run stably。Encoder fault：Encoder is an important part of servo motor，Used to feedback motor position and speed information。Encoder failure may result in inaccurate position control、Speed fluctuations or motor failure。Driver failure：Driver is the key equipment to control the operation of servo motor，Its failure possibility table
The selection steps and installation fixing method of ball screw are detailed as follows：The selection step of ball screw positioning accuracy requirements：The first thing to consider is the requirement of bearing positioning accuracy。Whether its processing equipment or industrial robots，It is necessary to ensure that the bearing can meet the accuracy requirements of the mechanical system。Definite lead：The lead of the lead screw bearing is determined according to the motor speed and linear speed。Under normal circumstances，The lead of the lead screw multiplied by the motor speed is greater than or equal to the required linear speed。Determine itinerary and related data：Determine the travel of the lead screw bearing、Relevant axial end data, etc。The length of the bearing should meet the actual working stroke、Nut length、Safety margin、Installation length
Large ball screw clearance is a common problem，It can be caused by a number of factors，And it will have an adverse effect on the operating accuracy and stability of the equipment。The following is a detailed analysis of the problems that lead to large ball screw clearance and how to deal with them：one、Lead to large ball screw clearance problem No preload or insufficient preload When the ball screw is not preload or insufficient preload，Due to its own weight or external load，There is a relative slide between the screw and the nut，This causes the gap to increase。This is particularly evident in vertically mounted lead screws。The torsion displacement is too large if the ball screw slenderness ratio（The ratio of length to diameter）oversize，Lead screw
Ac servo motor may encounter many kinds of faults during operation，These faults can usually be caused by machinery、Electrical and environmental aspects of the analysis。The following are several common AC servo motor failure reasons：one、Mechanical failure bearing wear：Excessive clearance after bearing wear leads to coaxial error between the center of the motor rotor and the center of the lead screw，Cause the mechanical system to jitter。Serious wear of bearing roller and cage will increase friction，Lead to“locked-rotor”，This in turn increases the response time of the servo system and produces vibration。Motor rotor unbalance：The dynamic balance of the motor rotor has defects in manufacture or becomes worse after use，formability
Planetary reducer and cycloidal pinwheel reducer are common reduction devices in the field of industrial transmission，They are different in several ways。Here are the main differences between them：one、Structural difference planetary reducer：Driven by planet gear、The sun gear and the inner tooth ring are composed。The structure is characterized by an internal tooth ring tightly coupled to the tooth box housing，At the center of the ring tooth is a solar gear driven by external power，In between is a set of planetary gears，The group of planetary gears relies on output shafts、The inner ring and solar teeth support floating during the period。When the force side drives the solar teeth，Can drive the planetary gear rotation，And follow the inner teeth
Stepper motor driver when in use，The following key issues need attention to ensure its normal operation and extend its service life：one、Power supply and electrical connection Power supply voltage and stability：Ensure that the power supply voltage matches the voltage required by the driver，Avoid drive damage due to overvoltage or undervoltage。Check power quality，Including ripple size and common mode interference suppression ability，To ensure the drive performance and subdivision accuracy。The driver is best supplied with unregulated DC power supply，The power supply current output capacity should be greater than the driver set current60%Or drive operating current100%（Choose according to the specific situation）。Electrical connection：According to
