Jiangmen decelerating motor: why does the motor move its shaft when it is used?
2020-07-06 863
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

The following points should be paid attention to when the deceleration motor is in normal operation
2020-07-06 841
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)

Jiangmen reducer: what kind of problems will happen if the motor wiring is wrong?
2020-07-06 749
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, t

The difference between reducer and gearbox
2020-07-06 780
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 tr

What industries are asynchronous motors used in?
2020-07-06 767
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 ordin

Selection principle of motor lubricating oil
2020-07-06 721
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 th

Jiangmen motor wholesale: the correct storage method of motor
2020-07-06 772
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 mak

What is the difference between asynchronous motor and synchronous motor?
2020-07-06 793
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 carry
