Q:What's the function of carbon brushes for AC motors?
AC motor brush: brush effect can be used for DC motor or AC motor commutator or slip ring, as sliding contact body import and export current, its thermal conductivity, and good lubrication performance, and has certain mechanical strength and direction of the spark of instinct. Almost all motors use carbon brush, which is an important component of the motor
Q:Which is better, alternating current tubular motor and direct current tubular motor?
The alternator is concerned, it can realize the direct energy feedback to the grid (but must ensure 4 conditions: the same voltage amplitude, phase and phase sequence of the same, the same frequency); but the DC generator power is required to process the alternating current into the inverter (DC said rectifier, the DC the process that converts the AC inverter), to feedback to the grid. So it also needs to increase the power of the inverter.
Q:Alternating current motor commutation
A sinusoidal voltage with a lead of 90 degrees or a phase of 90 degrees after a large capacitor is generatedAnd the original voltage can form a set of voltage difference of 90 degrees phase,.2 group voltage together can control its directionIf it's 90 degrees ahead, it's turning right. Then it will be reversed after 90 degrees
Q:What are the classifications of AC motors?
According to the different rotor structure, three-phase asynchronous motor can be divided into two major categories, squirrel cage and winding. Among them, squirrel cage is the most widely used.
Q:How does the PLC control the speed of the motor?
See what you choose the motor, the general AC motor does not need PLC, you can use the frequency converter speed, how much speed you can change the frequency of inverter output current. If it is a stepping motor or a private server, a drive is needed, and a PLC is used to send a pulse control drive to drive the motor. PLC each sends a pulse, the motor turns an angle.
Q:Can AC motors be controlled by frequency converter?
Yes, three-phase induction motors are available
Q:What is the difference between stepping motor and servo motor and three-phase asynchronous motor? What are the advantages of their differences?
Servo motor servo motor principle: also known as the executive motor, DC and AC servo motor is divided into two categories, servo motor rotor is permanent magnet drive control of the U/V/W three-phase power electromagnetic fields, the rotation of the rotor in the magnetic field, at the same time with the motor encoder feedback signal to the drive, the drive according to the feedback value compared with the target value, the rotor rotation angle adjustment. The accuracy of the servo motor is determined by the accuracy of the encoder (line number).Advantages: as servo motor with motor encoder to form an internal closed loop, the control accuracy is very high, so that it can operate normally at high speed. The drive can communicate directly with the host computer.Disadvantages: high price, long supply cycle of imported goods, high maintenance costs.
Q:Comparison of AC motor and direct current motor
Disadvantages of AC motor1. the starting and regulating speed of AC motor is poorAlternating current motor can be divided into synchronous motor and asynchronous motor according to speed.
Q:What is brushless motor, no and brush what is the difference?
The difference between a brush motor and a brushless motor is whether it is equipped with a conventional brush commutator. The commutation of the brush DC motor is always achieved by touching the graphite brush with the ring commutator mounted on the rotor.The brushless motor will feedback the rotor position back to the control circuit through the Holzer sensor, so that it can learn the accurate time of the motor phase commutation. Most brushless motor manufacturers produce motors with three Holzer effect positioning sensors. Since brushless motor has no brush, it has no relevant interface, so it is cleaner and less noisy. In fact, it needs no maintenance and longer service life.
Q:The working principle of AC motor!
At present, there are two kinds of AC motors commonly used: 1 and three-phase asynchronous motors. 2 、 single-phase AC motor. The first type is widely used in industry, while the second is used in civil electric appliances.
