Single-phase motor is a small power single-phase asynchronous motor, generally using single-phase AC power supply (AC220V) power supply; Usually there are two phase windings on the stator, and the rotor is an ordinary squirrel cage type; Here is a simple understanding of the working principle of single-phase motors with Senli Motor.

Gridlock current is the current measured while keeping the rotor at rest, and the motor gridlock is a situation in which the motor still outputs torque when the speed is zero, which is generally mechanical or artificial. Here is a look at the locked-rotor current of the three-phase asynchronous motor with Senli Motor.

When the load has no strict requirements on the starting torque of the asynchronous motor and the motor starting current must be limited, the motor meets the 380V/Δ connection conditions, and the stator winding is connected into a triangle when the motor is running normally. Today, Senli Motor Xiaobian mainly talks about star triangle step-down starting.

Leakage protector is a more effective means to prevent electric shock, can meet the needs of safe electricity, to ensure the normal operation of equipment, but at present, many factories will choose not to install because of the increase in the cost of installing leakage protector and the deterioration of the stability of the power supply. Here is a small series of Senli motor together to understand the leakage protection of three-phase asynchronous motors.

The operating principle of the torque motor is exactly the same as that of the general squirrel-cage asynchronous motor, but there are differences in structure, such as the use of materials with higher resistivity as the guide bar and end ring of the rotor, mainly because of the difference in characteristics, the rotor resistance will be much larger than the rotor resistance of the ordinary squirrel-cage motor. Let's take a look at this picture:

Torque motor is a special motor with a large number of poles, which can achieve low speed and gridlock, in such cases the motor does not kneel to cause damage, but can provide a relatively stable torque supply to the load, of course, it can also provide a torque in the opposite direction, we call the brake torque, its shaft is not a constant power output power but a constant torque output power.

We know that the variable frequency motor can use the frequency converter for speed regulation design, then the ordinary three-phase asynchronous motor can be variable frequency speed regulation? The answer is yes, to know that the inverter is not designed for the frequency conversion motor, the following and Senli motor Xiaobian together to understand the frequency conversion speed regulation of ordinary three-phase asynchronous motors.

Want to solve the three-phase asynchronous motor and other motor products are not burned out in the production process, the more effective way is to use the frequency converter, and now the brand of frequency converter technology is more mature, the quality is guaranteed, and the price can not be too expensive, compared with the occurrence of accidents, or burned out the motor is still more cost-effective.

Because the speed of the AC asynchronous motor is less than the speed of the rotating magnetic field, so we call the asynchronous motor, it should be basically the same motor, can be divided into induction motor and AC commutator motor, which induction motor is more widely used, can be divided into single-phase asynchronous motor, AC and DC dual-purpose motor and repulsion motor.
Details >
Asynchronous motor as a kind of AC motor, is widely used in small electromechanical equipment, its load speed and the frequency ratio of the power grid is not necessarily a constant relationship, will change with the size of the load, if the load torque is larger, then the speed will be lower, below and Senli motor Xiaobian together to understand it.

Long axis torque motor products, suitable for winding and winding scenarios, can be customized for different industry scenarios, to meet the requirements of use. This product produced by Senli has the characteristics of reasonable structure, high efficiency, good characteristics and long service life.
Shengzhou Senli Motor19Old motor manufacturers, with a number of their own motor production lines, from the shell, shaft, rotor, stator are independent production, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports. From the shaft machining to the whole machine assembly are completed independently. Truly realize factory direct sales.
Senli motor products are used180°High temperature resistance all copper coil material, torque motor products can be used with different rotors (ordinary rotors/Steel rotor), rotor of different motor characteristics are different, we from the shell, shaft, rotor, stator are produced by the independent, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports.
