- Q:What is the starting method of ac motor?
- The starting method of ac motor is mainly: direct start-up, star delta start-up, auto-de-voltage start, soft start and frequency converter start-up.
- Q:What is an ac driver? And the principle! Thank you very much!
- Motor servo ac motor drive is also called the implementation, in the automatic control system, is used as actuators, converts the received electrical signal into angular displacement or velocity of motor shaft output. Divided into two major categories of dc and ac servo motor, its main characteristic is, when the signal voltage is zero no rotation, speed decreases with the increase of torque and uniform, Servo actuator is the control part of servo motor.
- Q:What is the effect of the ac motor on the connection of direct current
- If you want to run soybean milk machine with a 48V battery, you have to use the inverter to power the UPS power supply
- Q:Which is good for dc motor and ac motor?
- According to the actual situation, dc motor needs dc power supply.I hope my answer will help you.
- Q:How do ac motor maintenance and maintenance?
- After all inspection is required, the motor can be started. Motor starts, no-load running for 30 minutes, observe whether there are abnormal phenomena, such as noise, vibration, fever found abnormal situation, should take measures to stay is eliminated, can be put into operation. When starting a linear motor, the starting rheostat should be connected to the rotor circuit. For the motor that has the brush lift mechanism, should put down the brush, and disconnect the short circuit device, close the stator circuit switch, the trigger rheostat. When the motor is close to the rated speed, the electric brush is lifted, the short circuit device is closed, and the motor is finished.
- Q:What is the difference between ac motor and dc motor?
- We know that the three-phase power supply phase phase difference is the voltage on the phase between 120 degrees, three of the three-phase asynchronous motor stator winding on the spatial orientation also sent 120 degrees, so that when zhongtong into the three-phase power supply in the stator winding, stator windings creates a rotating magnetic field, the stator windings creates a rotating magnetic field, rotor conductors (cage) will cut the lines of magnetic force of a rotating magnetic field and induced current, the current in the rotor conducting bar and interact with a rotating magnetic field to produce electromagnetic force, electromagnetic force produced by electromagnetic torque drive rotor rotating magnetic field along the direction of rotation. In general, the actual speed of the motor is below the rotational speed of the rotating field.
- Q:Why don't I have a dc 12V without a brush motor and I can connect to a third phase 12V?
- If the voltage is completely same can use frequency converter to drive the brushless dc motor, brushless dc machine is three windings of the synchronous motor, they are ultimately form a rotating magnetic field, is just the difference between the open loop and closed loop.
- Q:What are the advantages of the dc welder and ac welder? The better one?
- compared with ac arc welding machine, dc welding arc stability, not easy broken arc and small six, splash. Dc arc welding machine can weld acid and alkaline welding rod, communication can only seven alkaline welding rod, welding machine prices, see you need to how much current welder, relatively speaking, dc welder expensive eight. Very save electricity, dc arc welding machine, is the development trend in the future. Personal recommendations dc welding machine. There is one of the biggest advantages is the dc welding machine is very light, 200 a to ten catties of convenient also move '
- Q:How does the three-phase ac motor achieve constant power or constant torque output
- Is generally frequency converter to realize, in the power supply of power frequency 50 hz, motor with frequency converter to belt, the inverter output below 50 hz, the motor is constant torque output, but in the inverter output above 50 hz, the motor is constant power output.
- Q:The electric spark machine USES ac motor or dc motor!
- The upstairs talk is too absolute. The control mode of the spark machine is relatively simple, and the power of the motor is smaller, under 100W. Most electric spark machine is made of dc servo motor and electronic ruler.
