- Q: There are several methods for alternating current motor
- There are two ways of alternating current motor: 1, power brake, reverse connect braking - will the three-phase power supply cord of the motor exchange of two lines, make access to the motor phase sequence, on the other hand, a rotating magnetic field inversion (in contrast to the rotor turning), the electromagnetic torque is a braking torque, motor soon stopped, must stop the motor when power off, otherwise the motor start to reverse. 2, reverse connect braking pull - motor work normally, the load torque pulling reverse rotation, at this time of the electromagnetic torque is a braking torque, the braking torque motor reverse speed is not fast, but they will not stop the motor
- Q: Comparison between ac motor and dc motor
- The advantages of a dc motor The dc motor has good starting characteristics and speed regulating characteristics The torque of dc motors is greater It's cheaper to repair. Dc motor is more energy-efficient than communication.
- Q: What is dc and ac servo motor?? What are the features?
- Input or output a rotating motor for direct current energy. Its simulation speed control system is generally composed of two closed-loop, speed closed-loop and current closed-loop already, in order to make the two can coordinate with each other, play a role, set up two controller in the system, adjusting the rotational speed and current respectively. Two feedback closed loop on structure by using a nested structure of ring set of a ring, this is the so-called double closed loop speed regulation system, it has the advantages of quick dynamic response, strong anti-interference ability, thus is widely used. Usually consists of a PI or PID circuit by analog transport. Signal conditioning is mainly used to filter and enlarge the feedback signal. Considering the mathematical model of the dc motor, the simulation speed control system dynamic transfer function relationship in the process of simulation of the speed regulation system debugging, due to the parameters of the motor or load mechanical characteristics have a great difference with the theoretical value, often require frequent replacement R, C and other components to change circuit parameters, in order to obtain the desired dynamic performance indicators, very trouble to do so, if applied by programmable analog device controller circuit, system parameters such as gain, bandwidth, and even circuit structure can be modified by the software, debugging is very convenient
- Q: How to eliminate the electromotive force of ac motor
- You have a fundamental error in this question. There must be an anti-electromotive force in the motor running as an electric motor. If you want to run the motor, you don't have a countercurrent, so the motor is running as a generator.
- Q: What is the difference between asynchronous and synchronous in the three-phase motor?
- The asynchronous motor is induced by induction. The principle is that, after the stator winding plus the three-phase voltage, the rotational magnetic field is formed, and the conductors on the rotor are cut off the magnetic force line, so the electric potential is generated. And because the bars are connected, the current is generated. At this point, we think of what we learned in junior high school -- "a charged conductor can produce motion in a magnetic field." So, such an electric motor is called "induction motor". For asynchronous or induction motors, the number of the rotor's rotor is automatic induction stator. You can also say that the rotor has no polar number. (this is an example of an armature winding on a stator.) The asynchronous motor does not have a pivot/turn field. The main difference between the two main differences is that there is no work, no work can be made, and it can be absorbed. Asynchronous motors can only absorb no work. Synchronous motor is synchronous with the power grid, and the asynchronous motor speed is slightly lower than the speed of the grid. Synchronous motor speed is synchronous with ac frequency 50Hz power supply, i.e., the two pole motors are 3, 000, 4, 1500, 6, 1000, etc., and the speed of the asynchronous motor is slightly lagging, which is 2, 2880, 4, 1440, 6, 960, etc.
- Q: The ac motor with more than one kilowatt will be activated by the launcher
- This there is no hard and fast rules, basically see your lines and transformers, as well as the requirement for the quality of power supply, and the line protection fixed value setting, general motor impact current when starting for the normal 8 and 13 times that of the large capacity motor can cause voltage fluctuations, for high precision processing equipment production can say deadly, so considering comprehensive factors above, a lot of places can choose soft start way start or frequency converter drive, I have seen more than 200 kw, 100 kw motor USES the soft start, specific also depends on the enterprise itself situation, generally more than eighty kw adopt soft start more.
- Q: What is the braking mode of ac motor? What are the characteristics
- Energy consumption braking Motor to cut off the ac power at the same time, for any two of the stator winding of additive has been flow power, to produce a static magnetic field, rely on the inertia of the rotor rotating cutting the static magnetic field to produce braking torque
- Q: Common problems with ac motor
- Prevention: (1) remove the pulsating flux and the power supply harmonic (such as the ac reactor in the output side of the converter); (2) when the motor is designed, the bearing seats and the base of the sliding bearings are insulated, and the outer and end of the rolling bearings are insulated. 2, why can't the general motors be used for plateau areas? At altitude, the commutation of the electric motor, the electric corona (high voltage motor) and the dc motor are adversely affected. The following three aspects should be noted: (1) high elevation, the larger the motor, the smaller the output power. But when the temperature rises with elevation, it is sufficient to compensate for the effect of elevation The rated output power of the motor is constant.
- Q: 380v's ac motor operates under 330v voltage
- It is normal to be able to be driven, the difference is a few dozen volts different, it is only to calculate to be able to discover, the surface is not visible to the naked eye.
- Q: What is the connection of ac motor
- Triangle: the above three terminals to answer the three phase line of three-phase power supply, the following three should pay attention to connect the terminals, U that U2 with wires and V at the end of phase head end V1 nipple, V phase V2 with wires and W at the end of phase head end W1 nipple, W phase W2 with wires and U at the end of phase head end U1 short answer.
