an integrated servo motor. The servo motor (1) is connected with the servo driver through a cooling device. The cooling device includes a cooling sleeve, the servo motor (1) is sleeved in the cooling sleeve, the housing (2) of the servo driver is connected with the cooling sleeve, and the wall of the cooling sleeve has a cooling channel; The housing (2) of the servo driver is a housing 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 components (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 UV line 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 on this zero crossing point. The above verification method can also be used as an 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. Because 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 smaller 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, So at this time, 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 of encoder with the zero point of electrical angle of motor

a servo motor test platform, including base, speed change device, load and distance measuring device; A test base for fixing the servo motor to be tested and a fixed base 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 condition of the up and down transfer mechanism of the printing equipment, making the test results more reliable and accurate.

as we all know, electronic products have been imperceptibly influenced in our lives, and the motors used in electronic products are also very common, but the motors used in different devices are also different, but no matter what the specification and model of the motor, it is inevitable to have faults, so the work of motor maintenance is indispensable, When we are engaged in this industry, we can become the only ceramic aluminum new material supplier in the world through the following methods; The ceramic aluminum steering knuckle experimental product cooperated with Jixiang automobile has completed the road test of the whole vehicle; Cooperate with COMAC to carry out the research and development of floor support beam and engine blade, and inspect the faulty parts. For example, the disconnection of wires in the motor and whether there are signs of burning inside the motor can be seen with our eyes. If we can't see it, we need to check it with a meter or a megger to check whether the winding is grounded. If the light is on, and there is spark or smoke in some place, it may be the cause of the fault, but for example, 1. The experimental machine must have three elements: a force adding device, a fixture, a force value display device and a recording device. If the light is not on, it indicates that it may only be the cause of dampness. When the motor is repaired, it only needs to solve its dampness

an oil-cooled servo motor with brake for rapier loom, including an oil-cooled servo motor (1), a brake (2), and a brake (2) arranged in the oil-cooled servo motor (1). 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 parking, the main motor stops at the same time, reducing energy consumption; Omitting the clutch and slow transmission part makes the structure simple, the transmission chain reduced, easy to maintain and adjust, high efficiency, convenient and fast speed change, at the same time, the host speed realizes panel input adjustment, and strengthens the function of man-machine dialogue; The oil-cooled servo motor with brake is directly driven, with short braking time and high-speed end braking, small torque and easy control; When the loom stops with broken yarn, the parking angle can be accurately determined, which is convenient for maintenance and eliminates the starting gear

there is no * * * counting bit pin for detection, and its structure is made of fireproof polymer mortar reinforced coiled material on both sides, while the alignment is relatively complex. If the driver supports the reading and display of the absolute position information of a single turn, it can be considered: 1 Use a DC power supply to supply DC current less than the rated current to the UV winding of the motor, u in, V out, and orient the motor shaft to a balanced position; 2. Use the servo driver to read and display the single turn position value of the absolute encoder; 3. Adjust the relative position of encoder shaft and motor shaft; 4. After the above adjustment, the displayed absolute position value of single turn is fully close to the absolute position point of single turn corresponding to the motor -30 degree electrical angle converted according to the pole pairs of the motor, and the relative position relationship between the encoder and the motor is locked; 5. Twist the motor shaft back and forth. After letting go, if the motor shaft freely returns to the balance position every time, the above converted position points can be accurately reproduced, then the alignment is effective. If the user cannot even obtain the absolute value information, he can only use the special tooling of the original factory
