Q: In the ac motor, he is excited, excited, and excited. What is the difference between: He wound, is that the rotor is a set of power supply, the stator excitation coil is another power supply, two sets of power supply is independent and not directly on the electric contact, unless the closed-loop control of the motor in general mechanical and electrical properties are hard, and is adjustable speed and torque. That features more hard!

Q: Ac motor speed control method: Disadvantages: The maximum speed of the output shaft is 80% ~ 90% of the synchronous speed of the motor. The transition difference power of the speed adjustment process is converted into thermal energy and low efficiency. (7) the rotor resistance speed adjustment Advantages: The technical requirements are low and easy to master; The cost of equipment is low; No electromagnetic harmonic interference.

Q: How does ac motor winding be classified?: There are many kinds of ac motor winding, which are divided by phase and single phase and three-phase winding. It has a single layer winding and a two-layer winding. The single layer winding is the same type, single chain, cross chain and cross. Double layer winding and wave winding; The number of slots in each phase of each phase is an integer or a fraction, and there are two forms of slot and fraction. But the principles of the winding are consistent.

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: Can ac motors be used to speed control?: Only the frequency converter motor can be used to adjust the speed of the transducer, and the ordinary motor can not be adjusted by the transducer. But it's ok to start ac motors with a frequency converter. Because when the speed is low, the ventilation of the electric motors deteriorates, and the fever is severe enough to keep working.

Q: The calculation method of the weight of copper wire used for ac motor: It is often surrounded by a center, which has a high insulation layer. The cable has the characteristics of internal electricity and outer insulation.

Q: What happens to the ac motor plus dc: The fans of different manufacturers use different motors. If you use a series of exciting or shunt motor, dc or ac. If you're using an asynchronous motor, and you're not falling, it's going to burn, and you're not braking. If you use the permanent magnet synchronous motor, it will brake, and the electrical opportunity will be positioned in a fixed Angle. Of course, you can't add full voltage. Remember, motor coil inductance is a big, in the absence of rotating against potential offset voltage, it to direct current (dc) is equivalent to short circuit, if not, step-down will burn.

Q: What is the speed of the general motors: The speed of the motor is also the rated speed of the motor. The speed of the motor at the rated power. The speed of the motor, which is full load, is also called full load speed. Use the symbol "n" to indicate the unit is "RPM". Two, different purpose and type of motor, different speed. Three, motor speed calculation of synchronous speed = 60 * the logarithmic frequency/poles (n = 60 * f/p) n -- -- -- -- -- -- -- -- motor speed (numble), unit: revolutions per minute (RPM) F -- -alternating current frequency (frequency), unit: Hz P - - the magnetic pole logarithm (pair), unit: right (p). 8 extreme: 60 * 50/4 = 750 RPM, and asynchronous RPM is slightly reduced by about 735 RPM.

Q: What is the normal current of the three-phase motor of 3KW: So, for common communicators, the open loop control and the motor plug are not able to control the torque. If the servo ac motor is adopted, the closed-loop speed control, Angle control and position control can be blocked. For ordinary motor, you can consider, mechanical lock or jammed, mandatory locked-rotor, has completed the user's technical requirements, and then let go of mechanical plugging turn institutions, for the next process control. Ac motors are easily burned if plugged or missing. Must first understand the motor winding dc resistance of the dc resistance is under 15 Ω (motor dc resistance is smaller, the greater the power from less than 1 Ω), if the blocked or lacks when the motor has lost its ac impedance, so only under 15 Ω loop resistance of the motor, then the current can want to how much (380 v, 0.35 KW, for example: 380 present 15 = 25, 25 A was greater than the motor coil current over-current value). Often lack of phase, so the motor over-current protection (by the hand of my circuits are lack of phase, over-current protection), the first one but problems is that the current changes, this will protect the motor.

Q: What is the difference between a three-phase synchronous motor and a three-phase asynchronous motor search: The principle of asynchronous motor is mainly to enter three phase alternating current in the stator, which produces a rotating magnetic field, which is n0, which is synchronous speed. Different magnetic poles, p, at the same frequency f = 50Hz, will produce different n0, n0 = 60f/p. Here's how it works: Symmetrical three phase winding ventilation with symmetrical three phase current, to produce a rotating magnetic field, magnetic field line cutting rotor winding, according to the principle of electromagnetic induction, rotor winding of e and I, rotor winding by the effect of electromagnetic force in the magnetic field, electromagnetic torque, which make the rotor rotation, the rotor output mechanical energy, drive the mechanical load. Rotor speed n < n0, so called asynchronous motor. S = (n0-n)/n0, which is called the slip rate, is an important parameter to the asynchronous (motion) machine. SN is the rated slip.
