an integrated servo motor, the servo motor (1) is connected with the servo driver through the cooling device, The cooling device comprises a cooling jacket, a servo motor (1) is sleeved in the cooling jacket, a housing (2) of the servo driver is connected with the cooling jacket, and a cooling channel is arranged in the wall of the cooling jacket; The shell (2) of the servo driver is a shell made of metal heat-conducting material with a closed cavity inside, and a fan (11) is installed inside; The electric junction box (16) is located in the cooling jacket, and the encoder (17) is connected to one end of the central shaft of the servo motor (1) close to the electric junction box (16); The servo driver is provided with a shockproof device for protecting the electronic component (12) installed therein. After adopting this structure, the heat dissipation effect is good, the cooling effect is better, and the maintenance is convenient

after removing the DC power supply, verify as follows: 1 Observe the U-phase signal of the encoder and the back EMF waveform of the motor with an oscilloscope; 2. rotate the motor shaft, the rising edge of the U-phase signal of the encoder coincides with the zero crossing point of the UV line back EMF waveform of the motor from low to high, and the z-signal of the encoder also appears at this zero crossing point. The above verification method can also be used as the alignment method. It should be noted that at this time, the phase zero of the U-phase signal of the incremental encoder is aligned with the phase zero of the UV line back EMF of the motor. Since the U-phase back EMF of the motor is 30 degrees different from the UV line back EMF, after such alignment, the phase zero of the U-phase signal of the incremental encoder is aligned with the -30 degree phase point of the U-phase back EMF of the motor, and the electrical angle phase of the motor is consistent with the phase of the U-phase back EMF waveform, Therefore, the phase zero of the U-phase signal of the incremental encoder is aligned with the -30 degree point of the electrical angle phase of the motor. Some servo enterprises are used to directly align the zero point of U-phase signal for expanding the production range of encoder as soon as possible with the zero point of electrical angle of motor

a servo motor test platform, including a base, a speed change device, a load and a distance measuring device; A test seat for fixing the servo motor to be tested and a fixed seat for fixing the speed change device are formed on the base; The speed change device has an input shaft and an output lifting rod, the servo motor to be tested can be connected with the input shaft, and the load is installed on the top of the lifting rod; Wherein, the servo motor to be tested drives the speed change device through the input shaft, the speed change device drives the load to move up or down through the lifting rod, and the distance measuring device measures the displacement of the load. The displacement of the load driven by the servo motor to be tested can be measured with high precision, and the whole test platform can fully simulate the actual working conditions of the up and down transfer mechanism of the printing equipment, making the test results more reliable and accurate.

the main motor control frequency converter displays the Per1 fault code. Cause analysis of maintenance of Komori printing press: main motor tachometer (PG) failure. Maintenance results of Komori printing machine: after reinstalling the new PG and completing the self-tuning, the machine returned to normal operation. AC servo motors are widely used in China, but after the servo motors run to a certain period, various faults will occur. If we can timely judge the cause of the fault and do some simple fault treatment at the first time, it will help prevent the expansion of the fault. We have summarized some fault causes and fault treatment in the servo motor maintenance work, For the reference of AC servo motor users: the motor can not rotate after power on, but there is no abnormal sound, odor and smoke. In the Siemens CNC system configured for CNC machine tools, the drive motor is divided into spindle motor and servo motor. When the motor stator, rotor and bearing are faulty or the built-in encoder of the motor is damaged, we need to disassemble the encoder for repair or replacement

an oil-cooled servo motor with brake for rapier loom, which comprises an oil-cooled servo motor (1) and a brake (2). The oil-cooled servo motor (1) is provided with a brake (2). The invention adopts an oil-cooled servo motor with a brake to directly drive the loom, and adopts an oil-cooled servo motor with a brake to directly drive the loom. When stopping, the main motor stops at the same time to reduce energy consumption; Eliminating the clutch and slow transmission part makes the structure simple, the transmission chain is reduced, it is convenient for maintenance and adjustment, the efficiency is high, and the speed change is convenient and fast. At the same time, the host speed realizes panel input adjustment, and strengthens the man-machine dialogue function; It is directly driven by oil cooled servo motor with brake. If the braking time is short and high, the weight reduction effect is especially outstanding. The braking at the speed end has small torque and is easy to control; When the loom stops with broken yarn, the stop angle can be accurately determined, which is convenient for maintenance and eliminates the starting gear

for the spindle motor, if the encoder is replaced or installed, it can be commissioned as long as it is installed in the corresponding position with a special tool, and it is not necessary to adjust the angle and position of the motor shaft or encoder. However, for the servo motor, the feedback value of the displacement sensor must be measured in strict accordance with the installation requirements of the encoder. As long as there is a little error in the installation process, there will be an alarm in the encoder and the machine tool cannot be started or a runaway occurs, resulting in scrapping of the motor or damage to the mechanical parts. Therefore, proper installation is very important. The following is a summary of the common alarm phenomena we encountered during the maintenance of Esther servo motor. We hope it can be helpful to users using Esther servo motor. Esther servo motor maintenance - overload alarm a the wiring of the servo motor is wrong or there is leakage in the wiring (1) the U, V and W phase lines of the motor are connected incorrectly (2) whether the connector on the side of the servo motor is inserted improperly. The servo driver does not match the model of the motor. Check the driver model and motor model. The mechanical load of the matched driver or motor greatly exceeds the rated motor, but it is regrettable that the torque
