Three-phase asynchronous motorThe prerequisite for rotation is a rotating magnetic field, and the stator winding is used to generate the rotating magnetic field. The stators are usually separated by three Spaces120°When the stator winding passes through the three-phase power supply, it creates a rotating magnetic field, which is Three-phase asynchronous motor的基本工作原理。

Usually in the process of production and use, is there any situation in which the torque motor runs unsmoothly? When the operation is not smooth and the regulation is poor, we generally think of pressure regulation, then what are the commonly used pressure regulation methods? Here is a simple understanding with Senli Motor Xiaobian.

Three-phase asynchronous motor technology in China has been very mature, due to the market segmentation of products, motor performance gradually formed differences, such as torque motor, brake motor, deceleration motor and other products; It is said that the motor industry is "one point of price, one point of goods", but because there are many motor manufacturers, the quality price is also different. If you want to find products with excellent performance and stable quality, you must choose a guaranteed manufacturer.

There are many types of single-phase motors, which can be divided into two categories according to different starting methods. One is the covered pole motor, which can be divided into two types: the salient pole cover pole and the hidden pole cover pole resistance phase splitting type; The other type is the split-phase motor, which can be divided into capacitive split-phase and inductive split-phase.

When the brake motor is energized, the electromagnetic brake behind the motor is energized and suctioned. When the motor is energized, the direct current of the coil creates a suction force to separate the two friction surfaces at the tail, and the motor freely rotates.

Single-phase double-capacitor motor is called single-phase double-value capacitor asynchronous motor, which is a single-phase asynchronous motor based on the principle of capacitor phase separation. Unlike single-phase single-value capacitors, the circuit of this motor is respectively connected with a starting capacitor and a running capacitor, and the positive and negative rotation is achieved by replacing the main and secondary windings of the motor.

Is it found that after the three-phase asynchronous motor is used for a long time, the surface will form rust spots, and there will not be a lot of rust at the beginning, but gradually increase and increase? This is because there is no timely maintenance treatment, and if the time is longer, the rust area will increase, and in serious cases, it will affect the normal use of the motor.

Induction motor winding is made up of many coils (turns) of wire, if the insulation is not good, the superimposed between the coils will be short-circuited, so that a part of the coil is directly short-circuited off does not work. If the asynchronous motor has a short circuit between turns, then the vibration will increase, the current will increase, and the output will be relatively reduced.

The distribution of two-phase windings on the stator of small power single-phase asynchronous motors and the difference in power supply can produce different starting characteristics and operating characteristics. The following is the content of the working principle of single-phase asynchronous motors organized by Senli Motor. Let's understand it together!

Three-phase asynchronous motor is divided into fixed frequency and frequency conversion, ordinary three-phase asynchronous motor, that is, fixed-frequency motor, then there are many small partners will have questions, can the fixed-frequency motor be used as a frequency conversion motor? Here is a simple understanding with Senli Motor Xiaobian.
