- Q:Dc motor input direct current, after the commutator, does it change to alternating current?
- Generally speaking, dc brushless motor is a kind of ac motor, which is consistent in principle. But the alternating current is a positive, and the direct current is a trapezoidal wave. If you would have a ac electric flux to the dc motor, the first thing to remove the dc motor commutator, and want to ensure that the correct wiring, but also the size of the control current, prevent motor burn out.
- Q:Why does a single motor have a series of capacitors
- In a three-phase current, the current in each phase of the phase is in itself a phase difference. The capacitor induction motor has two winding, namely the starting winding and the running winding. The two windings vary by 90 degrees in space. String on the startup winding capacity of a large capacitor, when running and start the windings by single alternating current (ac), because of capacitor in the startup winding current on time than the running winding current advance Angle of 90 degrees, to reach the maximum value. In time and space form two of the same pulse magnetic field, make the air gap between the stator and the rotor produces a rotating magnetic field, under the effect of rotating magnetic field, the induced current in the motor rotor, current and rotating magnetic field interact to produce electromagnetic torque, motor rotation. This is why uniphase motors are connected to capacitors.
- Q:What is the normal current of the three-phase motor of 3KW
- Normal ac motor, including FM motor, is not allowed to be plugged. By the external characteristic curve of ac motor, the ac motor will generate a "subversive current" burning machine when plugging. At this time the converter, if the vector is controlled, the motor is plugged and the torque current is not controllable. I've done this experiment. If the speed of more than 5 hz, can control the torque current (size can be smooth adjustment), and, using the encoder feedback is better than not using encoder feedback.
- Q:Any 220V ac motor can be reversed?
- Theoretically yes. Now there are only three lines of single phase motor. This type of motor is made by the manufacturer, which connects the starting winding and the main winding to the interior directly. This motor cannot be turned upside down by an external method if it is not modified.
- Q:Is the motor for general electric tools ac motor or dc motor?
- In general, it is a series of motor, so it is ac motor. Dc motor is used to drive the charging tool using dc motor. And the three-phase machine, like the concrete vibrator, is a three-phase machine. If it is a direct current supply, there must be a rectifier power supply, because the power supply is 220V, which must be fully dc to be used. The commutator, it is recommended that you baidu, because this is involved in the electric road map and so on, and some basic knowledge of the motor, which is not difficult to do.
- Q:Which is good for dc motor and ac motor?
- The ac motor is simple, efficient, inexpensive and convenient to maintain, so it is widely used, but it is not easy to adjust. Dc motor is convenient, so dc motors are used in places where speed adjustment is higher. Now, the variable frequency regulation develops rapidly, the performance is very good, the trend that replaces dc motor greatly. The energy storage of the hydraulic disc spring mechanism and the energy storage of the electric spring mechanism do not need to be adjusted, so the use of ac motor is ok. Domestic electric motors are completely satisfied.
- 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:Single phase capacitor ac motor speed regulation why does not have corresponding frequency converter
- Single-phase ac motor from principle is converted by the three-phase ac motor, is just one of the phase is generated by capacitance mobile phase 90 degrees, if meet with frequency conversion governor drive the work by the capacitance of the problem. The variable frequency governor has the input single phase 220v, the output three-phase 220v variety, only choose star/Angle 380v / 220v three phase motor to work.
- Q:What is the difference between ac motor and dc motor?
- The dc motor is the magnetic field, which is moving in the field. Ac motor is magnetic rotation motion, and conductor motionless. Dc motor are divided into stator winding and rotor winding. The stator winding magnetic field is produced. When general dc. The stator winding is fixed polarity of the magnetic field generated. The rotor flux direct current in the magnetic field force. The rotor in the magnetic field force then spin. Direct current institutions to build complex. Cost is high. Ac motor stator winding and rotor conductors. Shaped like a squirrel cage rotor conductors between conductors and conductors with silicon steel sheet. Also have some ac motor rotor windings. The spinning principle of three-phase asynchronous motor Three-phase asynchronous motor to spin the prerequisite is to have a rotating magnetic field, three-phase asynchronous motor stator winding is used to produce a rotating magnetic field
- 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
