- Q: What's the difference between an excited motor and an ordinary motor?
- Exciter and excitation generator is important equipment of power plants, it is produced by coaxial prime mover rotational dc, for excitation voltage to establish a magnetic field to the rotor of the generator
- Q: What is the difference between a step motor and an ordinary motor
- Stepper motor and the general difference is mainly lies in the form of the pulse drive (send a pulse control system, can give in a rotary Angle of motor), because of the characteristics of step motor can be combined with modern digital control technology (particularly suitable for mechanical and electrical integration products). However, it is inferior to the traditional closed-loop dc servo motor in the accuracy, speed range and low speed performance of the step motor. It is possible to use stepping motor in an environment where precision is not particularly high, and the step motor can be characterized by simple structure, high reliability and low cost. When used properly, it can even be compared to the performance of dc servo motors.
- Q: How is the servo motor parameter chosen
- There is a general maintenance manual, you see the motor model and then you have a number in the back, which is the motor parameter.
- Q: Direct drive motor control mode
- The control board is the same as the general permanent magnet motor. The problem is you is to point to the need to control the motor start-stop, or to control the torque (your this kind of motor is primarily a torque motor), and you need to control analog or digital control. After certain, the circuit design is convenient. Need your motor driven load characteristics, work environment, such as the control response speed, accuracy, voltage, power, etc., and whether the high temperature, high humidity, high dust, high electromagnetic interference, etc., all of these have an effect on circuit design.
- Q: How do you solve the problem of stepping motor jitter
- It is usually possible to set the current value on a finalizer, and try it on a smaller scale. Note that too small a current can cause jitter, but the noise is low, not obvious. Also, the current is too small, high-speed rotation may need longer acceleration time, highest speed will be limited, need to find a balance between the two.
- Q: If the speed of a normal motor is adjusted by the frequency converter, the speed can exceed the rated speed, and if the current power is above the rated speed, what is the change in current power
- General motor frequency control of motor speed can exceed the rated speed, with the increase of the frequency of the motor voltage is reduced, this is the V/F converter control function, so it won't burn motor! But it depends on whether your load is matched by the power of the motor, because no matter how much the motor speed increases the power of the motor is inconvenient! Can change big motor to solve problem! The best frequency of a general frequency converter is 400HZ motor frequency to 100HZ, which is no problem. It will only accelerate the wear and tear of the motor and the equipment without any benefit!
- Q: The problem of speed regulating motor and general motors
- Frequency conversion for speed adjustment, speed regulating motor is frequency conversion motor, which is integration with frequency converter, ordinary motor optimization design, of course, but with general motor and frequency converter not too big difference, no single common motor speed control function. By tuning the pump if the requirements for precision of speed is not very high (not less than 0.5%) is no problem, just ordinary motor and frequency converter in the installation and operation, as well as reading is more troublesome, and must choose the appropriate power inverter (is greater than the power of the motor). The life of the ordinary motor and frequency converter generally does not reduce back, of course is related to the frequency and the number
- Q: What is the cause of the overheating of the servo motor
- 4: the inner hole of the bearing is eccentric, and the shaft is wiped. : 5: the motor ends or the bearing cover are not flat; 6: there is no calibration of the coupling between the motor and the load, or the belt is too tight; 7: the bearing clearance is too large or too small; The motor shaft bends.
- Q: The amount of the machine is doubled, all the other motors are unchanged, the rated torque and the speed change.
- The core thickness of the motor is doubled, and for the ideal click, you can think: Both the load and the rated speed are the same as the original 1/2. Both the rated torque and the torque torque are twice as large.
- Q: What is the difference between the decelerating step motor and the normal step motor?
- The decelerating step motor is a gearbox installed in front of the step motor. Lower the speed of the step motor to increase torque.
