Q:How does the three-phase ac motor identify the phase
What you're talking about is the traditional start of the de-stress In fact, there is a soft start and frequency converter
Q:Dc brushless motor and ac motor
Brushless dc motor stator winding is the star connection, the rotor is made of permanent magnet and a rotor position sensor to detect the rotor position feedback to the controller, the controller is dc power supply, it according to the position sensor feedback signal makes the stator winding current respectively, forming a rotating magnetic field, the mechanical properties of the brushless dc motor is harder.
Q:Dc motor power 13KW for ac motor
I don't think the power will change. The current and the voltage are going to change, but the product should not change
Q:Who knows the main difference between dc motor and ac motor
As the name suggests, dc motors use direct current as a power source. Ac motor is used as an ac power supply. According to the structure, the principle of dc motor is relatively simple, but the structure is complex and not easy to maintain. Ac motor is complex but relatively simple, and is easier to maintain than dc motor. The dc motor introduces the current to the rotor armature through the brush and the commutator, so that the rotor can force the force in the stator field. Ac motor (commonly used ac asynchronous motor, for example) is to put the ac electric flux into the stator winding, thus in the rotor creates a rotating magnetic field in air gap, rotating magnetic field in the rotor winding induced current, which make the rotor spinning force produced in the stator magnetic field. Dc motor speed regulation is simple, but use case is limited. Ac motor speed regulation is relatively complicated, but it is widely used because of ac power supply.
Q:Three phase ac synchronous motor is different from three-phase ac asynchronous motor
Structure and principle of The stator winding of synchronous motor and asynchronous motor is the same, the main difference is the structure of the rotor. The rotor of synchronous motor has dc excitation winding, so it needs to be coupled with excitation power supply to introduce current through the slide ring. The rotor of the asynchronous motor is a short-circuit winding, which generates an electric current through the electromagnetic induction. Asynchronous motor is simple, low cost, easy to install, use and maintenance. It has been widely used. Disadvantages low efficiency, low power factor of power grids. And synchronous motor with high efficiency is the capacitive load, can improve the power factor of power grid. Multi-purpose mining large not ready.
Q:What is the braking mode of ac motor? What are the characteristics
Reverse connect braking The power phase sequence of the motor stator winding is changed while the motor is cut off the normal operation power supply, and the reverse tendency of the motor is made to produce the larger brake torque
Q:The same power ac motor is more expensive than the dc
Of course, dc is expensive, dc motor is much more complicated than the three-phase squirrel-cage ac motor.
Q:How to change ac motor to dc motor
You might as well turn the direct current into an alternating current to make it easier to use the inverter to convert the dc point to ac
Q:Why does the motor need capacitance when the machine starts?
Only for single phase ac motor, because a single winding is unable to form a rotating magnetic field, the electric capacity of a rotating magnetic field is formed after phase-shifting three-phase don't need to, so it can synthesize a rotating magnetic field
Q:Why does ac motor speed control system replace dc motor speed control system?
Among them, the space vector PWM technology for the high voltage utilization and control algorithm is simple, low current harmonic, etc in the ac speed regulation system has been more and more used
