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:Three phase ac synchronous motor is different from three-phase ac asynchronous motor
use Synchronous motors are used mostly in large generators, while asynchronous motors are used almost exclusively in motor situations. The synchronous motor can adjust the power factor by the excitation. The power factor of asynchronous motor is adjustable, so in some large factories, application of asynchronous motor is large, can be added a synchronous motor for condenser, used to adjust the plant and the power factor of power network interface. However, due to the synchronous motor of high cost, maintenance workload is big, now commonly used capacitance compensation power factor. Synchronous machine with exciting winding and the slip ring, need the operator had a higher level to control excitation, in addition, compared with those of asynchronous machine maintenance free maintenance workload is bigger; So, as an electric motor, most current asynchronous motors are chosen.
Q:How to control ac motor speed
Ac motor is synchronous and asynchronous. The synchronous motor is at the same speed as n = 60f1 / p; If the speed adjustment words can only be tuned. The speed of asynchronous motors is n = 60f1 (1-s)/p; There are three ways to speed adjustment: A. Variable pole (p) speed adjustment. 2. Frequency conversion (f1) speed adjustment. 3. Change the differential rate s speed adjustment. There are four different kinds of changes: This is the variable stator voltage. The rotor resistance of a winding asynchronous motor is adjusted. The electromagnetic clutch speed adjustment. The double feed speed and cascade speed control of the wire wound asynchronous motor.
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 power of ac motor
Three-phase ac motor, three phase ac motor rated power = square root of 3 x x x rated current x rated voltage power factor efficiency.
Q:Can ac motors be used to speed control?
Hello, the question is first to determine what is your use and how to speed it up.I hope my answer will help you.
Q:The power consumption of a three-phase ac motor is equal to the line voltage cross current. How do you explain?
The calculation formula of three-phase symmetric load; The power P is equal to the square root of 3 U line I cosine phi is 3I2R. The line voltage refers to the parallel voltage between the two phase lines (a-b a-c b-c), and the phase voltage refers to the parallel voltage of the relative zero (a-0, b-0, c-0). In a power distribution system that is directly grounded in three phase four lines; Line voltage is equal to phase voltage square root of 3, phase voltage is equal to line voltage over square root of 3, line current equals phase current.
Q:Why is a single phase ac motor that can be adjusted by voltage
In simple terms, if the voltage is reduced and the rotor spins at the same speed, the stator gets a small current. Electromagnetic torque is reduced, in under the action of load torque, the same slip increase led to the decrease of the rotational speed, speed fall in reflection impedance decreases, and according to the size form again low impedance of the rotational speed of voltage and current of balance, and maintain at a low speed.
Q:Why do elevator door motors use dc instead of ac?
Because the dc voltage is more stable.Dc voltage reliability and stability are high.
Q:Is the servo motor a dc motor or ac motor?
What is a step motor? A step motor is an actuator that converts electrical impulses into angular displacement. Popular point: when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle (and the step Angle). You can control the amount of angular displacement by controlling the number of pulses, so that the target is accurate. At the same time, you can control the speed and acceleration of the motor by controlling the pulse frequency. There are three types of steps: permanent magnetic (PM), reactive (VR) and hybrid (HB). The permanent magnet step is generally two phases, the torque and volume are small, the step Angle is usually 7.5 degrees or 15 degrees. The reaction type step is generally three-phase, can realize the big torque output, the step Angle usually is 1.5 degrees, but the noise and vibration are very large. Developed countries such as the United States and Europe were eliminated in the 1980s. Hybrid step refers to the advantage of mixing permanent magnet and reactive type. It is divided into two phases and five phases: the Angle of two phases is 1.8 degrees and the Angle is 0.72 degrees. This step is the most widely used.
