• 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

  • 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
