- Q: If the value of the capacitor on a motor is smaller, it can also be installed in other motors
- Don't keep using it. The capacity will continue to decrease until it is completely invalidated and has no value.
- Q: How does the motor stop
- Emergency stop switch: just for a switch, usually use red or yellow mushroom head button, plays the role of the emergency stop in control circuit, so that the emergency stop switch The first method, which is also the usual addition, sets a closed contact switch in tandem with the motor's contactor coil circuit. It is possible to power the contactor in the job, so that the electric motor that runs through the contactor is lost to the purpose of the emergency stop. Method 2: there are also some three phase power switch (motor power) with control contact. Use the emergency stop switch to control the three-phase power switch. The electric motors that are run by the contactor are lost to the purpose of an emergency stop. The first is gm, the second is more expensive. Supplement: Is three motor, there is a knife, and later began to work, I have a red emergency stop switch, I'd like to know more things, so pick up to press the machine stop? You can buy another contactor. Follow the first method.
- Q: What is the difference between a servo motor and a direct drive motor?
- These two are not a concept Servo motor means that this motor is driven by high frequency pulse driven by servo actuator, which can achieve fixed Angle, fixed speed and fixed torque output. He's talking about the type of motor. A direct drive motor is a direct and rigid connection between the motor and load, without any transmission or coupling in the middle. He's talking about how the motor is used. The servo motor can be connected directly to the load or through the transmission device load. The dc motor can be a servo motor or other motor.
- Q: The difference between capacitor motor and general motor
- It is. Capacitor start motor, because of its running winding is, reverse phase winding set, so as long as the switch, and start running winding winding concatenated direction, can be convenient for motor inverse, along the direction of motion.
- Q: A 2.2 KW motor will require a lot of electricity a day
- It is not accurate to calculate simply because you are not considering the load rate of the motor, and the load rate of the pump is less than 75%. The most accurate method is to install the meter.
- Q: How does the heat of dc motor control
- There are several reasons for the fever of dc motors: The current of the actuator is larger than that of the motor The speed of the motor is too fast The inertia of the motor and the torque of the positioning torque are high, so even the medium speed can be hot, but it does not affect the life of the motor. Motor demagnetization points in 130-200 ℃, so in 70-90 ℃ belongs to the normal phenomenon, as long as less than 130 ℃, generally do not have what problem, if you really feel overheated, the drive current set the speed of the motor about 70% of the rated current or reduce one
- Q: What are the characteristics of plateau motors? Why can't the general motors be used for plateau areas
- General motor's normal use of the environment temperature is 5 to 40 degrees, at an altitude of 1000 meters the following, the motor structure design and only meet the needs of the geographical climate conditions, so general motors can not adapt to the plateau region of bad environment.
- Q: Can you use a transducer to control the general motors? Recently, the factory has to renovate two 150 kw electric motors, which were previously controlled by the star delta, and now change the frequency converter, the electric motor is near the stove, the ambient temperature is higher. Please give me your opinion, thank you
- First introduce the frequency conversion motor: look from the appearance, the most obvious is characterized by frequency conversion motor have a single cooling fan, and a cooling fan has a special connection box. The cooling fan needs to be connected to the power supply alone, so that no matter how often the motor works, it will not affect the heat dissipation of the motor. Second, the frequency conversion machine manufactured by the regular manufacturer will be adjusted internally, and it will also strengthen insulation. If there is a problem with ordinary asynchronous motor, it should be analyzed according to the situation. For example, the motor is working in low-frequency areas, and the motor may be damaged by heat dissipation. If the motor is working in the medium-high frequency area, the ordinary motor can also use the frequency converter. Also, it is the insulation problem of ordinary electric motor, the proposal is to install output reactor. Of course, it's not necessary.
- Q: What is induction motor? What is the difference between ordinary motors? What is the price of a small induction motor? Is there a inductive dc motor?
- Induction motor is the use of electromagnetic induction to rotate the rotor, and the difference between ordinary motor is a coil is the stator, rotor and ordinary motor coil is usually, and brush.
- Q: The difference between a two-speed motor and a regular motor
- The difference between a two-speed motor and an ordinary motor: Double speed motor Belong to the speed regulating pole asynchronous motor variant, it is by changing the connection of the stator winding method to change the stator rotating magnetic field pole logarithm, which changes the speed of the motor. The speed of the motor changes the way the winding is connected, which is to change the magnetic poles of the magnetic field to change its speed. Two-speed motor (fan), low speed at ordinary times, sometimes fan on high speed turning, mainly through the following external control circuit switch to change the way the motor coil winding connection.
