Q:The working principle of AC motor!
The prerequisite of the three-phase asynchronous motor to rotate is to have a rotating magnetic field, and the stator winding of the three-phase asynchronous motor is used to generate a rotating magnetic field. As we know, but the voltage phase power phase between the difference of 120 degrees in phase three, a stator winding of the three-phase induction motor in the spatial direction is 120 degrees, so when in the stator windings in three-phase power, the stator winding will produce a rotating magnetic field, as shown in Figure 1 in the process of its generation. The graph is divided into four moments to describe the generation of the rotating magnetic field. In each period of the current, the rotating magnetic field rotates in space for a week, i.e., the rotation speed of the rotating magnetic field is synchronous with the change of the current. The rotation speed of rotating magnetic field is: n=60f/P, f is power frequency, P is magnetic pole, logarithm and N unit is: revolutions per minute. According to this formula, we know that the speed of the motor is related to the number of poles and the frequency of the power supply. To this end, there are two ways to control the speed of the alternating current motor: 1, change the magnetic pole method; 2, frequency conversion method. In the past, the first method was used, and now the variable speed control of AC motor is realized by frequency conversion technology.
Q:Can the welding line of AC welding machine be dead?
Electric welder no-load voltage in 50V ~ 90V, and the highest level of safety voltage 42V, no-load voltage is higher than the safe voltage, this is not the main safety factors of two lines; in addition, the general electric welding arc ignition, working voltage 16V ~ 35V needed to maintain the arc, although in a safe voltage range but, in the bad environment such as welding on metal structures, metal containers, pipes or under water and wet locations for welding, welding if the poor body condition, body resistance is very low, may cause electric shock, safe voltage is not absolutely safe.
Q:In the main circuit of AC motor, fuse can be used as short circuit protection, can it play the role of overload protection at the same time, why?
If the current of the motor is working normally is 10A, if there is a fuse that can work stably in the case of 10A, the case of 11A will be blown. So because the motor load for a short period of time (a few seconds) suddenly become larger, up to 12A, and then returned to normal, it is not to endanger the safety of the motor (motor temperature rise, not what) without the need for protection, but the fuse has melted. That's what we don't want to see.
Q:Is permanent magnet synchronous motor AC servo motor?
First of all, the classification of motor: servo motor is divided into AC servo and DC servo, in which AC servo and synchronous and asynchronous points. Permanent magnet synchronous motor (PMSM) is a kind of synchronous AC servo motor.
Q:Brushless DC motor is AC motor or DC motor, why?
Brushless motor is a direct current motor.Adopt DC work, adjust pulse speed by adjusting pulse width.AC motor works by alternating current and adopts frequency converter to adjust speed.
Q:Is the 380V single-phase AC motor the same as that of the 220V AC motor?
The single-phase motor has two windings, that is, the starting winding and the running winding. The two windings are 90 degrees apart in space. On a starting winding connected in series with a large capacity capacitor, when running and starting winding winding by single-phase alternating current, because the capacitor make the starting current in the winding in time than the current running winding advance angle of 90 degrees, the first to reach the maximum.
Q:How to distinguish AC and DC machines
This also increases the manufacturing cost of DC motors to a certain extent. The alternator is concerned, it can realize direct energy feedback to the grid (but must ensure 4 conditions: the same voltage amplitude, phase and phase sequence of the same, the same frequency); but DC generator power needs to convert AC inverter (DC rectification process called, the direct current into alternating current the process that the inverter can be feedback to the power grid). So it also needs to increase the power of the inverter.
Q:Causes of insulation breakdown in AC motor voltage withstand test
In the withstand test, the test voltage is too high and exceeds the specified value.
Q:Can AC motors use direct current?
AC motors use direct current, because the motor will not rotate, it will burn the coil in a short time.
Q:How many kW or more AC Motors should be started with the starter?
Starting of an electric motorArticle 2.3.1 when starting an electric motor, its terminal voltage shall be able to guarantee the starting torque required by the machine, and the voltage fluctuation caused in the distribution system shall not interfere with the work of other electrical equipment.Article 2.3.2 when starting an alternating current motor, the voltage on the distribution bus shall comply with the following requirements:First, in general circumstances, when the motor starts frequently, it should not be less than 90% of the rated voltage. When the motor is not started frequently, it should not be less than 85% of the rated voltage.Two, the distribution of buses on the lighting or other voltage fluctuations are more sensitive to the load, and when the motor is not frequently started, shall not be less than 80% of the rated voltage.Three, the distribution of buses on the other electrical equipment, can be guaranteed to start the motor torque conditions; for low voltage motors, but also to ensure that the contactor coil voltage is not less than the release voltage. Article 2.3.3 the choice of starting modes for cage motors and synchronous motors shall comply with the following provisions:When the following conditions are met, the motor shall be started with full pressure:1 when the motor starts, the voltage of the distribution bus meets the requirements of clause 2.3.2 of this specification:2 、 mechanical energy can bear the impact torque when the motor is started at full pressure;3. The manufacturer has no special rules for the starting mode of motors.Two, when not meet the full pressure starting conditions, the motor should buck start, or choose other appropriate starting method. Three, when the speed control requirements, the motor should start with speed regulation.
