The reducer is a kind of independent component which is composed of the gear drive, worm drive and gear - worm drive enclosed in the rigid shell. It is often used as the reducer transmission device between the original moving parts and the working machine.Reducer is a lot of national economy in the field of mechanical transmission device, industry involving product categories include all kinds of gear reducer, planetary gear reducer, worm reducer, also includes a variety of special transmission device, such as growth device, speed regulating device, and including flexible transmission device, all kinds of compound gear, etc.The products and services include metallurgy, nonferrous metals, coal, building materials, ships, water conservancy, electric power, construction machinery and petrochemical industries.
China's reducer industry development history has been nearly 40 years, in the national economy and national defense industry in various fields, reducer products have a wide range of applications.Food light industry, electric machinery, construction machinery, metallurgy machinery, cement machinery, environmental protection machinery, electrical and electronic equipment, road building machinery, water conservancy machinery, chemical machinery, mining machinery, conveying machinery, building materials machinery, rubber machinery, petroleum machinery and other industries have a strong demand for reducer products.
Huge potential market has given rise to competition in the industry, in the cruel market competition, the reducer industry enterprises must speed up eliminating backward production capacity, to develop the high efficiency and energy saving products, make full use of the national energy-saving products huimin engineering policy opportunities, increase the intensity of product updates, adjust product structure, pay close attention to national industrial policies, to cope with the complex economic environment, maintain a good momentum of development.
- Q:MATLAB for ac asynchronous motor simulation, speed signal and torque signal when the result is negative?
- This shows that the parameters of the asynchronous motor have a problem, such as the rotor resistance and reactance of the motor. The load torque of the electric motor is too big, the machine can't bring up, so it shows that the speed is always going in the negative direction. You can modify the motor parameters, or reduce load torque
- Q:The ac motor is not positive and negative, so how do you achieve positive and reverse?
- Three-phase motor fixed wiring to produce a circular rotating magnetic field, single phase motors through a secondary coil series capacitor formed an elliptic rotating magnetic field, as long as the connection method is fixed, the above two is fixed in the direction of the field Change the wiring method, can change the rotation method of the magnetic field, realize positive and backward turn
- Q:What does ac motor have to do with a carbon brush
- Ac motor carbon brush: carbon brush can be used in dc motor or ac motor commutator or slip rings as export import current sliding contact, its conductive, thermal conductivity and good lubrication performance, and has certain mechanical strength and commutation spark instincts. Almost all electric motors use a carbon brush, which is an important component of an electric machine.
- Q:Please communicate the motor. It is possible to speed the speed with a governor
- Many household electric fans using bidirectional thyristor phase shift control of motor speed, this kind of speed is actually reduce the input current make motor with fixed running quickly and can only reduce the speed. Like dimming lamps, they are forced to regulate.
- Q:What is the difference between a dc motor and a servo motor?
- Servo motors are widely used in various kinds of control system, can convert the input voltage signal to the motor shaft mechanical output, drag the control element, so as to achieve the control purpose.
- Q:What is the difference between alternating current motors and dc motors?
- Upstairs is a little irrelevant answer, the first people ask is the difference, again is the motor, not the generator! How it works: Dc motor installed a constant magnetic field, after the stator coil zhongtong current is generated electromagnetic force, so they will move, but the direction of the electric current to change, so will generally use brush, contact with the terminal. So the cost is higher. It is commonly used in servo motor, measuring motor and excitation motor. The ac motor has only one winding and the rotor is squirrel-cage. When a single-phase sinusoidal current in the stator winding, the motor can produce an alternating magnetic field, the magnetic field strength and direction interplanting sine law of change at any time, but is fixed on the spatial orientation, say again so the magnetic field is alternation pulse magnetic field. This alternation pulse magnetic field can be decomposed into two at the same speed and direction of rotation are instead of a rotating magnetic field, when the rotor static, the two rotating magnetic field generated in the rotor torque of two equal and opposite, making synthetic torque is zero, so the motor can't rotate.
- Q:What are the similarities and differences between the dc brushless and the ac brushless motor?
- So-called no brush, brushless, is also is this kind of motor does not rely on brush to change the polarity of the armature current, and usually by position detection device, such as hall, the light code disc detection such as location, and then in accordance with a certain control method, according to the position signal to change the polarity of the armature current.
- Q:How does the three-phase ac motor achieve constant power or constant torque output
- Three phase asynchronous motors running on motor. Three-phase asynchronous motor rotor speed is lower than the speed of the rotating magnetic field, rotor winding due to there is relative motion between magnetic field and induced electromotive force and the current, electromagnetic torque and interact with the magnetic field, the realization of energy conversion. Compared with the single-phase asynchronous motor, the three-phase asynchronous motor performs well and saves all kinds of materials. According to the structure of rotor, three-phase asynchronous motors can be divided into caged and winding type. The asynchronous motor structure of the cage rotor is simple, reliable, lightweight and inexpensive, and is widely used. The main drawback is the difficulty of regulating speed. The rotor and stator of a winding type three-phase asynchronous motor also set up a three-phase winding, which is connected by a slide ring, a brush and an external rheostat. Adjusting rheostat resistance can improve the starting performance of the motor and adjust the speed of the motor.
- Q:Ac motor speed control method
- The most common method is to add a matching frequency converter You can also use a gearbox
- 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.
