Q:Difference between energy consumption braking of DC motor and AC motor
When the motor is operated in an electric state, if the armature voltage U is suddenly dropped to zero, the armature is connected with an additional resistor R. The two ends of the armature are disconnected from the power grid and are quickly connected to an appropriate resistor. The motor is in the running state of the generator, converting the kinetic energy of the rotating part into electric energy and consuming the resistance. With the kinetic energy consumption, the speed decline, braking torque is also becoming smaller and smaller, so this brake method is still relatively high in speed, braking role is relatively large, with the decline in speed, braking effect also decreases.
Q:How can I change the alternating current welding machine into a DC welder?
This is: ZXG series silicon rectifier (dead silicon) arc welding machine, AC arc welding machine itself power factor is lower, plus rectifier loss will be lower. The power consumption is too large and uneconomical. It has belonged to the sort of our welder.
Q:What are the advantages of AC motors?
The coverage of AC motor power greatly, from a few watts to several 101000 watts, even millions of kilowatts. In the early 1980s, the largest turbo generator reached 1 million 500 thousand kilowatts.
Q:What is AC induction motor?
Three phase motors must be cut off at the same time when the 3 phase motor is switched off. You can't just cut off 1 or 2 of them. This will burn the motor. Usually, the electrician calls it "eating a single phase"".
Q:The actual power consumed by a three-phase AC motor is equal to line voltage * line current. How do you explain that?
For the three-phase motor whether delta or star connection, is the P= root 3*380v*I line *COS, line voltage 380V means, the other is right, you do not know where it comes from the formula. If you do not take the appropriate 3, that is the single phase load.
Q:How to synchronize two ordinary AC motors?
Frequency converter is one of the motors, one to two motors synchronous operation, can use frequency converter input control terminal function, to achieve the two frequency converter frequency settings. That is, using the command and deceleration commands at the end of the increase, the use of buttons on and off signals to increase or decrease the set frequency. In order to connect the inverter, when the growth rate of the button is closed, the command signal growth end, increase the output frequency of the inverter according to the acceleration time, growth button to keep the inverter output frequency is turned off; when the deceleration button closed, deceleration command end signal, the output frequency of the frequency converter to reduce the deceleration time, deceleration button keep the output frequency of the inverter is disconnected. By using the method mentioned above, the system can be tuned and fine tuned with the relay, so that the synchronous control of multiple motors can be achieved.
Q:What is the maximum speed of a three-phase AC motor?
This motor is divided into pole number, 2 pole motor synchronous speed 3000RPM; 4 pole motor synchronous speed 1500RPM; go down and so on
Q:The difference between a DC motor and an AC motor for a garbage collector
Of course, alternating current is good. Because the AC motor is more stable than the direct current motor, the performance is stable, the heating is low and the efficiency is high.
Q:How do ordinary AC motors brake?
Reverse brakingWhen the motor cuts off the normal power supply, the power phase sequence of the motor stator winding is changed so that a reverse braking torque is generated.
Q:What are the advantages of a DC motor and an AC motor?
Direct current motor (D.C.machine) is a kind of motor that realizes the conversion between DC energy and mechanical energy. When it is used as an electric motor, it is a DC motor. It converts the electric energy into mechanical energy. When the generator is running, it is a DC generator and converts mechanical energy into electrical energy.
