It is necessary to find out and find out the causes in time to eliminate them

Motor incineration is very common in daily life. The most effective preventive measure to prevent motor incineration is proper technical protection. The main protection methods are as follows: 1. Always keep the motor clean. When the motor is moving, it is necessary to always keep the air inlet clean. There should be no dust, water stains, oil stains and other sundries within at least 3m around the air inlet to prevent being sucked into the motor. If these dust, oil, and water are sucked into the motor, it will form a short-circuit medium, damage the wire insulation layer, form a turn-to-turn short circuit, increase the current, and increase the temperature to burn the motor. Therefore, it is necessary to ensure that the motor has sufficient insulation resistance and an outstanding ventilation and cooling environment, so as to keep the motor in a safe and stable condition during a long time operation. 2. Operation under extra load The main reason for motor overload operation is that the drag load is too large, the voltage is too low, or the driven waterproof motor factory machinery is stuck. When the motor moves under an overload condition, the speed of the motor will decrease, the current will increase, the temperature will rise, and the winding coil will overheat.

If the motor is overloaded for a long period of time, the insulation at the high temperature will fail and burn, which is the main reason for the motor to burn. Therefore, when the motor is in motion, pay attention to always check whether the operation of the transmission equipment is sensitive and reliable. Check the adjustment of the tightness of the transmission belt and the coaxiality of the coupling at any time. If there is a stuck phenomenon, stop it immediately to find out the cause and remove the fault. Then work again. 3. Three-phase current must be balanced. For three-phase asynchronous motors, the difference between the average value of any one-phase current and the other two-phase currents in the three-phase current is not allowed to exceed 10% in order to ensure the safe and normal operation of the motor. . If the current value of the single phase and the average value of the other two phases exceed the specified limit, it indicates that the motor is faulty. It is necessary to find out the cause and continue the operation after the fault is eliminated, otherwise the motor burnt out will occur. 4. Maintain normal temperature Always check whether the temperature of the bearing, stator, housing and other parts of the motor is abnormal. Especially for motors without voltage, current and frequency supervision facilities and without overload protection facilities, the supervision of temperature rise is particularly important. If the temperature rise near the bearing is found to be too high, stop the machine immediately to check whether the bearing is damaged or lack of oil. If the bearing is damaged, replace it with a new one before operating.

If the bearing is short of oil, increase the grease. Otherwise, the bearing will be further damaged, causing the frame to collapse, causing the chamber to be burned and the motor to be burned. 5. Investigate whether there is oscillation, noise and abnormal odor. If the motor oscillates, it will cause different shafts of the connected equipment to increase, which will increase the motor load, increase the current, and increase the temperature and burn the motor. Therefore, in the operation of the motor, you must often check whether the anchor bolts, motor end covers, bearing glands, etc. are loose, and whether the connecting equipment is reliable. If problems are found, you must deal with them in time. Noise and odor are the precursors of abnormal motor operation and faults. It is necessary to find out and find out the causes in time to eliminate them, otherwise the opportunities will be delayed, the faults will be expanded, and the major events of burning motors will be caused. 6. Ensure the normal operation of the starting equipment The technical condition of the starting equipment of the motor has a decisive effect on the normal starting of the motor. Otherwise, it is simple to burn the motor before it has entered normal operating conditions. Practice has proved that most of the reasons for burning motors are on the starting equipment. The protection of starting equipment is mainly cleaning and tightening. Contactor contacts that are not clean will increase the contact resistance, cause heat to burn the contacts, form a phase loss and burn the motor. Corrosion and dust accumulation of the core of the contactor sucking the coil will make the coil suck less tightly, and make fierce noise, increase the coil current, burn the coil and cause problems. Electrical control equipment should be placed in a boring, ventilated and easy-to-operate position, and regular dust removal should be performed. Tighten each wiring screw, check whether the contactor contacts are firmly in contact, and whether the mechanical parts are sensitive and accurate. Then make sure it starts smoothly without burning the motor.

Click-to-magnitude are inseparable from the processing and control of the motor.

The functional diversity of high-speed dome cameras means that product functions will be more powerful, applicable to different environments, and better compatible. Motion parameters, such as high-speed scanning of preset points, low-speed capture at large magnifications, cruise queues, pattern scanning, automatic tracking, and click-to-magnitude are inseparable from the processing and control of the motor. 2, simpler, More flexible installation methods. The indicators of the performance of the stepper motor are the low-speed control level and preset point accuracy, as well as stability. With the development of the economy, The speed of urban construction is constantly accelerating, the urban population is becoming denser, and the population mobility is increasing, which has caused urban security management issues such as transportation, social security, and increased difficulty in preventing key areas. The advantage has become one of the products that has developed rapidly in the security market in recent years, so it can be said that 'the construction of a safe city has promoted the rapid growth of high-speed ball and speed balls.

The third key component of the high-speed dome camera is the brush. The quality of the motor determines all of the high-speed ball. Better concealment. Effectively reduce the overall machine cost. With the increasing number and complexity of emergencies in social order, people ’s requirements for public safety protection are becoming higher and higher. The intelligence is mainly reflected in the intelligent recognition (Facebook recognition alarm, abnormal recognition alarm, license plate recognition, etc. 4. In short, the technical development of high-speed dome and the market need are a process of mutual influence and mutual promotion. On the one hand, there is a market demand to promote the further development of technology and better application to products; on the other hand, the development of technology will stimulate more market demand. There was a comprehensive and meticulous consideration at the beginning of planning. Differential pulse technology is used to control the rotation angle and speed, so that the high-speed ball can be accurate. The integrated high-speed smart ball has won the favor of consumers with its own advantages, especially With the development of urban public security monitoring, the high-speed ball has attracted attention. The diversity of functions, networking and intelligence can be said to be the main trend of current dome product development.

At present, high-speed domes generally use a dial switch or menu to select the protocol, and the machine is right. Of course, the specific implementation of this work is still not difficult. Humanization and generalization of operation Design will be an increasingly important factor affecting product marketing. The degree of image jitter during low speed control can reflect the performance of the high-speed ball; the accuracy of the preset point also depends on the precision of the mechanical structure and the performance and control level of the stepper motor. The indicators that show the performance of the stepper motor are the low-speed control level and pre- The placement accuracy and stability of the high-speed ball have a short history, but it has won the favor of users for its exquisite appearance, flexible control, and intelligence. 7. 5.
