Q:How to connect the AC motor?
There are two kinds of three-phase AC motorStar: the three connecting terminals are connected with three phase lines of the three-phase power supply, and the three terminals are shorted together with wires or metal pieces.
Q:Why should a single-phase AC motor start with a capacitor?
Because only the formation of a rotating magnetic field, the squirrel cage rotor will rotate, only increase the starting winding, but start winding must be shifted to start capacitor winding current advance main coil current of 90 degrees, the rotating magnetic field motor to rotate (motor power will start after the resection of the starting capacitor).
Q:Which is better, alternating current tubular motor and direct current tubular motor?
Good communication.The main difference between AC and DC motors is that the nature of the power supply is different. The AC motor uses alternating current. The generator sends out alternating current, while the direct current motor uses the direct current, and the generator sends out the DC point too
Q:What are the stator and rotor functions of an alternating current motor?
The role of the stator of an alternating current motor is:As part of the magnetic circuit of the motor and embedded stator windings. The stator core is laminated by 0.5mm thick silicon steel sheet, and the two sides of the brick and steel sheet are coated with insulating paint to insulate the sheets and sheets so as to reduce the core loss caused by the rotating magnetic field in the stator core. A plurality of same grooves are punched inside the stator core to be inserted into the stator winding.
Q:What is the maximum speed of a three-phase AC motor?
The fastest is the 2 stage motor, near 3000 revolutions per minute
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.
Q:How do I change the speed of the motor?
There are several schemes. The 1. is to change the ratio of the mechanical driving wheel and driven wheel driven by the motor. The 2. is to use mechanical transmission to change the speed of the motor. 3. is to use electronic governor to change the speed of the motor. As for which scheme to use, it depends on your environment.
Q:Is the motor in the inverter air conditioner a direct current motor?
Frequency conversion only for AC motors.The DC motor controls its voltage and changes its speed. Frequency independent. In one case, the frequency of direct current is 0. Therefore, the use of frequency conversion is simply can not control the DC motor.AC motors can vary the speed by changing their frequency, but they can not be controlled by changing the voltage. There is only one result of changing the voltage, and the motor must be destroyed.
Q:What are DC and AC servo motors? What are the characteristics?
A rotating motor with input or output as direct current energy. Simulation of speed control system it is generally consists of 2 closed loop, both speed loop and current loop, which enables the two to coordinate each other, play the role of the 2 regulators in the system set up, adjust the speed and current respectively. The 2 feedback closed loop adopts the nested structure of one ring and one ring in structure, which is called double closed loop speed regulating system. It has the advantages of fast dynamic response and strong anti-interference ability, so it has been widely applied. PI or PID circuit is usually composed of analog operational amplifier, and the signal conditioning is mainly to filter and amplify the feedback signal. Considering the mathematical model of DC motor speed control system, simulation of dynamic transfer function in the debugging process simulation of speed control system, because the parameters of the motor or load the mechanical characteristics and the theoretical value is different, often require frequent replacement of R, C and other components to change the circuit parameters, dynamic performance index to obtain the expected, do it is very troublesome, if the use of programmable analog components regulator circuit, system parameters such as gain, bandwidth and circuit structure can be modified by the software, it is very convenient for debugging.
Q:Relation of voltage, speed, voltage and torque of single phase AC motor
Motor power: P=1.732 * U * I * cos PhiMotor torque: T=9549 * P/n;Motor speed: n=60f/p, P for the motor pole count, such as four motors p=2;Note: when the frequency reaches 50Hz, the motor reaches the rated power, and then increases the frequency, the power will not increase, and will maintain the rated power.The motor torque is less than 50Hz, is proportional to the variation with frequency of F; when the frequency reaches 50Hz, the motor reaches the maximum output power is rated power; if the frequency of F in 50Hz and then continue to increase, the output torque is inversely proportional to the frequency change, because its output power is so big, you have to continue to increase the frequency of F, then the formula set in the above analysis, the torque is obviously reduced.
