- Q: The three-phase ac motor can be divided into which classes
- Classification according to the use Different applications of the three-phase asynchronous motors can be divided into drivers and controlling power. The motive power of driving power is divided into the motive of electric motor, electrical motor and other general motors. The motor is also divided into stepper motors and servo motors. Four, according to the structure of the rotor The motor is different from the structure of the rotor, which can be divided into cage induction motor and rotor induction motor.
- Q: Brushless dc motor, is it ac motor or dc motor? Why is that?
- Dc motor, only without brush and commutator, should be inside by hall sensor to detect the rotor position, make the drive circuit commutation, turn in one direction of motor
- Q: Ac servo motor can be divided into synchronous ac servo motor and induction ac servo motor
- Synchronous ac servo motor is more complicated than induction motor, but it is simpler than dc motor. Its stator and induction motor have a symmetrical three-phase winding on the stator. The rotor is different, and the different rotor structure is divided into two types: electromagnetic and non-electromagnetic. The non-electromagnetic type is divided into hysteresis, permanent magnet and reactive type. The magnetic hysteresis and reactive synchronous motor are inefficient, low power factor and small manufacturing capacity. The permanent magnet synchronous motor is used in nc machine tool. Compared with the electromagnetic type, the permanent magnet is simple, reliable and efficient. The disadvantages are large volume and poor launch features. But the permanent magnet synchronous motor with high remanence, high coercive force of rare earth magnets, than about 1/2, small dc electric dimension quality reduce 60 ﹪, rotor inertia reduced to 1/5 of the dc motor. Compared with asynchronous motors, the efficiency is high because of the use of permanent magnet excitation, which eliminates excitation loss and related stray loss
- Q: Can two phase ac motor not be able to install governor?
- Small power can, high power (with centrifugal switch) not ok.A resistance governor can be installed
- Q: Dc brushless motor and ac motor
- The dc motor is for direct current, but the coils inside the rotor are still alternating current circuit. A dc motor with a brush is replaced by a brush. Instead of a brush motor, the dc is converted into ac by a contravariant circuit and then coiled to the coil. The common one is the 12V cooling fan. It is commonly used in computer servers. Ac motor does not need a commutator (brush). Normally no permanent magnet is needed. ... To learn more about buying an electric machine, read it
- Q: How to control ac motors with dc 24V voltage
- Weak electricity controls strong electricity, which is the basic requirement of control. The voltage of DC24V can operate the coil of the relay, and then control the motor's three-phase ac contactor. It can also be used by PLC relay output module to operate the motor's three-phase ac contactor. In the motor start-up and protection circuit, the contactor is the component that controls the engine's stop. High power motor, which can be operation by the frequency converter, passive contact with remote start frequency converter, and drive the passive contact, can also be DC24V dc intermediate relay.
- Q: Is ac servo motor power fixed
- The power of ac servo motor generally refers to the output of the rated torque at the rated speed. This power is usually given at the specified temperature. The temperature rise permitted by the motor may be different. Ac servo motor is generally working under rated speed. From rest to rated speed servo motor in constant torque output. That is, the power of the ac servo motor at the rated speed range is zero to the rated power. The servo motor has a greater torque overload capacity, which is likely to be up to four times. The maximum instantaneous power is four times the rated torque. The most important electrical parameters of servo motor selection are static torque, rated torque, rated speed, and rated power. Because the servo actuator and the servo motor are supplied, the voltage of the servo motor is generally not considered. If there is any, it should be the dc bus voltage before the driver inverses. When we select the servo drive, just notice that it's connected to 220V or 380V.
- Q: How to connect the ac motor to turn and reverse ~!
- If two sets of coil resistance Can put the capacitance end connection to the other end If only two sets of coil resistance is not the same as the turned on the motor Open the secondary coil connection from outside transpositions to adjust and reversing
- Q: Who made the world's first ac motor?
- In 1867, the Belgian character ram was made into an improved alternator. Scientists in 1886, the Croatian American origin tesla made two phase winding type ac asynchronous motor model, and in 1888 and developed the principle of the tesla coil, and in 1891 made the tesla coil's patent, which laid a foundation for alternating current (ac) of the remote transmission. It can be said that Edison and tesla, the former is not the inventor of the direct current (dc), the latter is not the inventor of the alternating current (ac), the later this misconception is that from the current war at the end of the 19th century, because two people a stick to dc, another promote communication, and let people think they are dc and ac inventor (baidu encyclopedia "tesla" entry is written).
