Q:How does the brush motor control the positive and backward rotation?: Usually have a brush motor circuit with dc power supply, as long as change the brush across the electrodes at the ends of the power supply, change the direction of the input current, can change the motor and reversing.

Q:How does the communication motor work?: We know that the current is going to generate force in the magnetic field, and the wire is going to generate an electromotive force in the changing magnetic field. Ac motor plus ac voltage to the stator coil produces a rotating magnetic field, some of which is 1500 revolutions per minute

Q:Why does the motor need capacitance when the machine starts?: Only for single phase ac motor, because a single winding is unable to form a rotating magnetic field, the electric capacity of a rotating magnetic field is formed after phase-shifting three-phase don't need to, so it can synthesize a rotating magnetic field

Q:Who made the world's first ac motor?: Correct to say that they are both a master of power system, invented the dc transmission and alternating current (ac) transmission system, respectively, to promote the wide application of these two kinds of power system, due to the belong to different companies and the fierce competition. A competition eventually after a series of alternating current (ac) is found that the benefits of ac over dc, tesla also be regarded as the inventor of the alternating current (ac) in the history. Alternating current (ac) is not a tesla's invention is, actually, but tesla also have their own original invention, and many of them are super era, so this condition on tesla historical position as a great scientist.

Q:Ac frequency conversion air conditioning compressor is synchronous motor and asynchronous motor: The starting capacity is used on a single phase ac, the most common home air conditioning, which is used to activate the capacitor. Dc frequency conversion technology is new, I also in research recently, in principle, should be to turn ac to dc, dc into a square wave power supply, to the dc stepper motor, by controlling the square wave frequency to achieve the effect of frequency conversion, otherwise, the direct current (dc) itself is no frequency said.

Q:What is the difference between the excitation winding of ac motor and the armature winding?: Motor learning definition "armature" as the "main power circuit", as long as you think about the power of the stator loop or rotor circuit of large power, the big is the armature. The power is the voltage X current. Only the synchronous generator and the synchronous motor have excitation winding and armature winding. The general ac asynchronous motor is not excitation winding. Squirrel-cage asynchronous motor points and winding type two kinds big, the same stator winding structure, the squirrel-cage rotor cage bar, wound rotor rotor coil is an external device (can change the rotor impedance to realize variable speed). The "armature winding" is the "main power circuit" of the motor. Which power of the rotor and stator coil is "armature", needless to say, most stator coils are "armature winding".

Q:Ac servo motor can be divided into synchronous ac servo motor and induction ac servo motor: On the control strategy, based on the motor voltage and frequency control method and the mathematic model of steady state open loop flux trajectory control method can achieve good servo characteristic, the current widely used is based on the mathematical model of permanent magnet motor dynamic decoupling vector control method, which is the core of modern servo system control method. Although people in order to further improve the control characteristics and stability, and puts forward the feedback linearization control and sliding mode variable structure control, adaptive control theory, and does not rely on mathematical model of fuzzy control and neural network control method, but mostly on the basis of vector control additional application of these control methods. High-performance servo Control and must rely on high precision of rotor position feedback, people always wanted to cancel the link, the development without position sensor technology (Sensorless Control). Up to now, in the commercialization of the products, the sensorless technology can only achieve about 1:100 of speed ratio, can be used in some low for position and speed servo control situations of accuracy is not high, such as pure pursuit of quick start stop sewing machine servo control and braking, high performance processing for this technology is still a long way to go.

Q:Ac motor speed control method: Disadvantages: During the process of speed adjustment, the transfer loss is increased, which makes the rotor hot and less efficient. The range of speed adjustment is small; It is required to adopt high torque motor, such as special design torque motor, so the characteristic is softer, and a section is suitable for asynchronous motors under 55kW. (6) the electromagnetic variation clutch speed adjustment Advantages: The structure is simple, the control device is small and the value is cheap. Reliable operation and easy maintenance. No harmonic interference.

Q:Why does ac power connect capacitor: A large start current is provided to enable the motor to start successfully.Use the capacitance to change the Angle of the electric phase, causing the electrical Angle to leak 90 degrees.

Q:Is the brushless dc motor a synchronous motor or asynchronous machine? Thank you very much!: No brushless dc motor is dc motor, no asynchronous, synchronous problem. Only ac motor can be divided into synchronous motor and asynchronous motor. The so-called brushless dc, just use the switch instead of brush commutation function, ensure that motor armature always receive appropriate dc power supply to ensure their normal operation.
