- Q: Does the step motor belong to ac motor or dc motor?
- Step motor should be ac motor, and stepper motor is an actuator which converts electrical pulse 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.
- Q: The rated current of a single phase ac motor is several times that of an empty current.
- A small single-phase motor, which is rated at about twice the amount of an empty current
- Q: The difference between dc motor and ac motor
- Different speed control accuracy: Dc speed control does not change the load properties of the motor, and ac speed change the property of load. In other words, the frequency of the alternator is different. The resistance of the dc motor is constant while the voltage is different. Ac speed adjustment, due to unstable, it is difficult to realize fine speed adjustment. Dc speed adjustment, due to stability, it is easy to achieve fine speed adjustment, and several millivolt speed can be resolved.
- Q: How does the current transformer in ac motor work?
- The electromagnetic current transformer is widely used in the electric system, and its working principle is similar to the transformer. The wiring of the current transformer, as shown in the left. The characteristics of the current transformer is: (1) a coil in series in the circuit, and as a result, the number of turns in a coil current depends on the load current of the circuit under test. And has nothing to do with the secondary current; (2) current transformer secondary coil of the current meter and relay to the coil impedance is very small, so under normal circumstances, current transformer run in to a short-circuit condition. The ratio of a current transformer to a second rated current is called the rated mutual inductance of a current transformer Because the current I1n is standardized, the secondary coil rated current I2n is uniformly 5 (1 or 0.5), so the mutual inductance ratio of current transformer is also standardized. The kn can also be approximated as the number of turns for the transformer one and the second coils, which is the number of turns in the kn = N1 / N2 type, the number of turns for one or two coils. Current transformer is used to measure large current.
- Q: What are the advantages and disadvantages of synchronous motor and asynchronous motor?
- Asynchronous motor application: motor, its power range from several to tens of thousands of kilowatts, is in the industries of national economy and People's Daily life, the most widely used motor power for a variety of mechanical equipment and household appliances. For example, the machine tool, small and medium rolling steel equipment, fan, pump, light industrial machinery, metallurgy and mining machinery, mostly adopt three-phase Asynchronous Motor (Asynchronous Motor). Electric fans, washing machines, refrigerators, air-conditioners and other household appliances are widely used in single-phase asynchronous motors. Asynchronous motors can also be used as generators for wind farms and small hydroelectric plants.
- Q: Is it still a communication welder
- Of course the ac welder was used in sales; And it's not too small; But today's ac welders are mainly concentrated in high-power welders;
- Q: Dc motor and ac motor, which is better for mechanical hands?
- DC power amplification, but not to control steering servo DC signal, and is adjustable wide pulse signal, so as to obtain the high precision control. Pure DC signal can also control the rudder Angle, but control may be too long, for example, if you need to 31 degrees from left 30 degrees to the left, with DC signal may need to 1 second, and using PWM pulse may need only 0.1 seconds
- Q: How do ac motors keep moving in the same direction?
- Typically by capacitance phase out another phase Angle difference of alternating current (ac) effect on the secondary coil and main coil integrated into a rotating magnetic field up to cut off the secondary coil. As for the synchronous motor, the principle of some trouble, basic is asynchronous motor rotor into a rotor as dc motor. When it starts to become asynchronous start, starts in electricity, the rotor into sync, ha ha, also forgot to tell you that a speed ratio of the motor is rotating magnetic field of low speed asynchronous motor, the same is called synchronous motor, the speed of the rotating magnetic field is the synchronous speed.
- Q: What is the speed of the general motors
- There are many different speeds of the motor, the synchronous motor is n = 60f/p, and the asynchronous motor can be changed at the same speed, which is related to the synchronous speed
- Q: What's the total number of ac motor governor? The most common, each principle, the detailed point, the master thank you Please be more careful, the principle means thank you
- Ac motor speed governor generally refers to the electromagnetic speed regulating motor controller. Now the gear speed machine, also called ac motor speed, the best you know that will you use it first.
