- Q:What is the difference between a frequency converter and a regular motor
- The converter is a power control device that transforms the power supply into another frequency by using the power semiconductor device. We now use the frequency converter mainly adopts cross - straight - to pay way (VVVF inverter or vector control frequency conversion), the power frequency ac power first through the rectifier converts dc power supply, and then to convert the dc power supply frequency, voltage control of the ac power supply electric motor. The circuit of the converter is composed of rectifying, intermediate, inverter and control. Rectifying section for the three-phase bridge controlled rectifier, inverter part for IGBT three-phase bridge type inverter, and the output of PWM waveform, intermediate dc link for filtering, dc energy storage and buffer reactive power. Frequency changer: When selecting the frequency converter, make sure the following points: 1) the purpose of conversion; Constant pressure control or constant flow control. The type of load of the converter; The performance curve, such as a vane pump or a volumetric pump, is a special attention to the performance curve of the load, which determines the method of the application.
- Q:What is the difference between the two class motors and the four-stage motors?
- But, in fact, if the rotor is as large as four pole rotor between, each of the four pole rotor pole, relative only half of the poles, so Br also approximately half, almost the whole torque.
- Q:Can variable frequency control motor be used as a general motor?
- It depends on what kind of structure it is! If it's a three-phase asynchronous motor, you can
- Q:How does the heat of dc motor control
- 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 Some. When there is no failure, it is normally warm. Of course, the normal heat won't be too hot. Normal fever: One, the coil has the resistance, the current flows through the loss power; The magnetic field of the iron core has a "hysteresis loop". The iron core and the vortex, the magnetic energy that turns the electric energy into a part of the magnetic energy that becomes electric current and then becomes heat energy; There is friction between the mechanical rotating parts, and a part of the kinetic energy of the transition continues to change to heat energy.
- Q:The difference between servo motor and general motor?
- The insulation level, which is usually F or higher, strengthens the insulation strength of the ground and turns, especially considering the ability of insulation to withstand shock voltage. 2) to the problem of vibration and noise of the motor, the motor should be fully considered component and overall rigidity, trying to improve its natural frequency, in order to avoid and every force wave resonance phenomenon. 3) cooling mode: the general adoption of forced ventilation cooling, the main motor cooling fan is driven by an independent motor. To prevent shaft current measures, the bearing insulation measures should be applied to the capacity exceeding 160KW motors. Mainly produces magnetic circuit asymmetry, also can produce shaft current, while the rest of the high frequency component generated by the current role in combination, shaft current will increase greatly, which can lead to bearing damage, so often insulation measures. For constant power frequency converter motor, the special lubricating grease should be used to compensate the temperature of the bearings when the speed is over 3000 / min.
- Q:The difference between brushless dc motor and plain dc motor, where is its advantage
- If the simplest commutation circuit is taken, there is no difference between controlling and dc motors. The difference is that there is no such thing as a brush In other words, replace the commutation with electric electronics Other advantages are due to the absence of brushes
- Q:What is the difference between a single phase motor and a two-phase machine?
- Typically, the single phase motor is an electric motor, commonly used in small devices that start torque, such as electric fans and other small household appliances. In this motor, a small single-stage rotating hidden copper coil generates a rotating magnetic field. Each pole is surrounded by copper wire or copper bands; In order to prevent the current in the coil change (lenz's law) can produce induced current in the copper strip, so that every cycle maximum field strength across the surface, to produce a large enough lower rotating magnetic field to drive the rotor and the load on it. As the rotor increases its torque to the maximum, the field of the original (fixed rotation) will rotate as the rotor turns. These motors are hard to reverse unless the internal structure changes.
- Q:What is the difference between an energy-saving motor and a general motor
- Contrast with the normal Y series: losses of 15% to 25% and efficiency up 2.5% to 4%. 4. With the improved ventilation systems using highly efficient energy-saving fan of energy-saving motor air gap, the flux density distribution of reasonable design, make the motor efficiency index reaches more than GB18613-2006 grade 2 energy efficiency standard. Our energy-saving motors have outstanding features: 1. Efficient energy efficiency, lower running costs, and allow the final customer to recoup their investment costs within 9-15 months. Reliable performance is high, making the supporting equipment running smoothly, the failure rate is low, the maintenance cost decreases. Adopting imported high-grade bearing, manufacturing process is exquisite, once used, benefited from many years. Can be equipped with various accessories, the installation method is suitable for many situations. The product standard we adopt is at the cutting edge, the insulation and insulation are extremely abundant, the structure design takes care of and satisfies different customers
- Q:Is the servo motor more than the general motors? Why is that?
- The average injection machine can also save energy, whether it's a servo or a frequency converter, which can be used to save energy, but the difference is as follows: If you use a converter, the cost is low, (the converter cost is about 500 to 600 yuan per KW, and the servo is about 1,200 ~ 1500 yuan per KW). The frequency conversion of the frequency converter is lower than the servo, (the frequency of the frequency converter is 20% ~ 50%, and the servo is usually 30% ~ 70%). 3. The frequency converter with low maintenance cost, frequency converter by the localization of more than 10 years of history, has become increasingly stable, many occasions can be comparable with imported, while the servo is not very mature, average life is not too long, once out of the problem, the cost is very high. It depends on your financial situation and going to the statement, the company also produces servo, not in the fight against others, but after so many years of experience, the company's injection molding machine frequency conversion electric saving is very stable, like some big enterprises such as byd, unified group and other large enterprises are successfully used for years
- Q:What is a hydraulic motor
- Hydraulic motor is hydraulic motor, hydraulic motor is also known as the oil motor, mainly used in injection molding machinery, ships, Yang machine, engineering machinery, construction machinery, coal machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical industry, port machinery, etc.
