- Q:What is an ac driver? And the principle! Thank you very much!
- Speed response performance is different It takes between 200 and 400 milliseconds for a step motor to accelerate from rest to a working speed (usually a few hundred revolutions per minute). Better acceleration performance of the ac servo system, a panasonic MSMA 400 w ac servo motor as an example, from static accelerated to the rated speed 3000 RPM it takes only a few milliseconds, can be used for quick start-stop control occasions. To sum up, the ac servo system is superior to stepping motor in many performance aspects. But you can also use stepping motors to do the motor on a less demanding occasion. Therefore, in the design of the control system, the factors such as controlling requirements and cost, etc., should be taken into consideration.
- Q:Why does ac motor speed control system replace dc motor speed control system?
- The PWM control is the control core of the ac speed control system, and the final implementation of any control algorithm is almost done in various PWM controls. Has been put forward and the PWM control scheme of practical application to more than a dozen, articles about PWM control technology in many famous electric power international conference, such as PESC, IECON, EPE has formed at the annual meeting
- Q:How does the communication motor work?
- Tesla coil to form a rotating magnetic field, rotating magnetic field in the cage of alternating flux change, squirrel cage induction electromotive force formation, formation of induced current, induced current in the magnetic field force, produce with rotation, when balance, motor steady work.
- Q:What is the ac motor made up of?
- Car electric has two key components, one is a generator, and the car is powered by the car. The other is the motivation to start the car. The motor has a magnetic field and the armature and rectifying element, but the former is to convert mechanical energy into electrical energy, which converts electrical energy into mechanical energy, and the structure of the two is have very big difference. Previous auto generator is a dc generator, commutator rectifying, since the 1970 s have been phased out, now auto generator is mostly alternator, with semiconductor rectifier. It has the advantages of small size, large power, long life, low failure and low speed charging performance.
- Q:Comparison between ac motor and dc motor
- Such high-pressure transport means that smaller wires can be used to save costs. search And because of that, the exchange of these frequencies, 50HZ 60HZ, is less expensive. So it suits our national conditions better However, ultra-high voltage, long-distance transmission, for example, these provinces, are dc transmission, dc transmission can be more efficient use of effective area of the wire, the main is pure in impedance and affect the efficiency of ac. But dc power normally just at a distance, such as China, so in general can be more cost savings, but need to build on both ends of the rectifier and inverter equipment will ac to dc and dc to ac grid. So if it's a distance transmission, the cost is too high. Only for long-distance transmission.
- Q:If the motor through reducer drive the load, the load moment of inertia is to convert to the motor shaft, namely, divided by the square of reduction ratio, and, after conversion of moment of inertia of the moment of inertia/motor = inertia ratio?
- In general use ordinary ac asynchronous motor, need not calculate inertia, the characteristics of ac motor is that he didn't have enough output moment of inertia, which is driven too heavy, though the steady-state torque is enough, but the transient inertia is too large, then the motor started to be rated speed, the motor will slow fast first, slowly speed, eventually reach the rated speed, so the driver is not shivering, the control effect is not big. But due to choosing a servo motor, servo motor is depend on the encoder feedback control, so its startup is very rigid, must achieve speed and position of the target, at this time if the amount of inertia to withstand more than motor, the motor will be shaking. So when calculate with servo motor as a power source must fully consider the inertial factor, need to compute movement eventually convert to the motor shaft of inertia, through the torque, moment of inertia calculation start time M = J x B, J is the moment of inertia, B for the angular acceleration, the calculation of the torque M less than the start torque of the motor to achieve smooth start.
- Q:Question about the general motors?
- Alternating current general motors with stator coils and rotors are series of exciting! Its commutation needs to change the head and tail of the stator winding and the direction of the rotor commutator! As long as the connection is set! The connection is a turning point! In other words, you're turning the dc backwards! If there is no other electronic control element inside it will not burn!
- 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:Is it that all ac motors are bi-directional
- In addition to changing the power supply, some motors change the direction of the winding or the rotor direction
- Q:What is the difference between dc motor and ac motor?
- The dc motor is the magnetic field, which is moving in the field. Ac motor is a magnetic field rotating motion, while the conductor does not move. Dc motor are divided into stator winding and rotor winding. The stator winding magnetic field is produced. When general dc. The stator winding is fixed polarity of the magnetic field generated. The rotor flux direct current in the magnetic field force. The rotor in the magnetic field force then spin. Direct current institutions to build complex. Cost is high. Ac motor stator winding and rotor conductors. Shaped like a squirrel cage rotor conductors between conductors and conductors with silicon steel sheet. Also have some ac motor rotor windings.
