What industries are asynchronous motors used in?
2020-07-06 1122
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 1043
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 1121
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 1182
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
