• Jiangmen decelerating motor: why does the motor move its shaft when it is used?

    There is a special phenomenon of rotor shaft shifting in the process of motor use. Motor rotor out of the stator core, the occurrence of axial displacement, known as the rotor shaft. Under normal conditions, both ends of the stator core and rotor core are aligned, or the rotor is slightly shorter than the stator core. When the rotor core moves out of the stator core for 5 mm or more, the three-phase no-load current of the motor will increase significantly. After loading, the stator current will exceed the rated current value, which will overheat the motor. Together, there will be an uneven but regular buzz. If the motor rotor serious shaft shifting, the motor can not drive the load operation. What is the meaning of motor shaft shifting?

  • Jiangmen reducer: what kind of problems will happen if the motor wiring is wrong?

    Asynchronous motor is the most widely used motor at present. The wiring method of its motor winding is divided into star connection y and triangle connection Δ. The following Jiangmen speed reduction motor will introduce the result of wrong wiring. For a motor with star shaped stator winding, the voltage accepted by each phase winding, i.e. phase voltage, is 1 / 3 times (0.58 times) of the additional voltage (power line voltage) of the motor. In case of wrong connection and triangle operation, the phase voltage will increase to 1.73 times of the manufacturer's regulation. For example, if the power supply voltage is 380 V, the star operation, the phase voltage is 220 V, and the phase voltage is increased to

  • The following points should be paid attention to when the deceleration motor is in normal operation

    The following points should be paid attention to in normal operation: 1) check the heating and oil leakage of the bearing frequently, and replace the lubricating oil regularly. The lubricating grease of rolling bearing should not exceed 70% of the volume of the bearing chamber. 2) the temperature of deceleration motor in normal operation shall not exceed the allowable limit. During operation, the operator on duty should always pay attention to and supervise the temperature rise of each part. 3) pay attention to keep the interior of the reduction motor clean, and do not allow water drops, oil stains and debris to fall into the interior of the motor. The air inlet of the reduction motor needs to be kept unobstructed. 4) for wound rotor reduction motor, check the

  • What industries are asynchronous motors used in?

    Asynchronous motor is a kind of AC motor. The ratio of the speed of the load to the frequency of the connected power grid is not stable. It also varies with the size of the load. The greater the load torque, the lower the rotor speed. Induction motor includes induction motor, doubly fed induction motor and AC commutator motor. Induction motor is widely used, in the case of no misunderstanding or confusion, generally can be called induction motor as asynchronous motor. The stator winding of ordinary asynchronous motor is connected with AC power grid, and the rotor winding does not need to be connected with other power sources. Therefore, it has the advantages of simple structure, convenient manufacture, application and maintenance, reliable operation, low quality and low cost

  • Selection principle of motor lubricating oil

    The general selection principles of lubricating oil are as follows: 1. Working temperature: the working temperature will affect the viscosity change and lubrication effect of lubricant. Therefore, when the working temperature is low, the lubricant with low viscosity must be used. When the working temperature is high, lubricants with high viscosity or appropriate additives must be used. The viscosity of the selected lubricant has to be changed at different ambient temperatures. For example, if the same bearing is lubricated, a lubricant with a viscosity lower than that in the South or in summer must be selected in winter. If the operating temperature changes frequently, lubricants with good viscosity temperature characteristics must be used. In other words, in order to keep the oil film thickness unchanged in a certain range

  • Jiangmen motor wholesale: the correct storage method of motor

    First, if the motor is not used for a long time, it should be placed in a monotonous and ventilated indoor environment. And the indoor environment is relatively clean, no metal dust, no acid fog, salt fog, etc. When storing, pay attention to keep the motor covered with oil / water-proof material. 2. When the motor is not used for a long time, the following treatment should be done: 1. The motor should be maintained once, remove dust and oil, measure the insulation of three-phase winding, and make records; 2. The storage environment of the motor should adhere to the monotonous air circulation, there should be no water on the ground, and wood blocks should be filled at the motor accumulation place; the motor should not be the same as chemical drugs, such as acid, alkali, battery, etc

  • The difference between reducer and gearbox

    Reducer motor mainly refers to the gear motor assembled by gear box and motor. Its main function is to increase the torque and reduce the speed. It is widely used in many factories. It is generally decelerated by means of gearbox. Reducer motor refers to the integration of reducer and motor (motor), which can also be called gear motor or gear motor. It is usually integrated and assembled by a professional reducer manufacturer and integrated with the motor. The reducer motor is a kind of power transmission mechanism, which is used in applications where high torque is required and high speed is not required. For example: Automation

  • What is the difference between asynchronous motor and synchronous motor?

    The principle of asynchronous and synchronous motors are both based on the law of electromagnetic induction. The difference is that the symmetrical three-phase windings of the asynchronous motor are connected to the AC power supply. Even if the stator does not roll, a rotating magnetic field will occur because of the AC power supply. At this moment, the current will occur in the closed winding circuit. Therefore, according to the left-hand screw rule, the effect of the force on the current carrying conductor in the rotating magnetic field can be determined that the rotor winding is subjected to a directional electromagnetic force and electromagnetic torque effect (generally clockwise), so that the rotor winding rotates with the rotating magnetic field of the stator at the speed of N; while the stator winding of synchronous motor is spatially different by 120
