The reducer is an independent component composed of a gear drive, a worm drive, and a gear-worm drive enclosed in a rigid housing. It is often used as a deceleration drive between the prime mover and the working machine. It plays a role in matching the speed and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.The reducer is an independent component composed of a gear drive, a worm drive, and a gear-worm drive enclosed in a rigid housing.

- Q:Why does dc motor reduce the voltage regulating ac motor?
- The rotational speed of the ac motor is determined by the rotational speed of the rotating field, while the rotational speed of the rotating field is only related to the frequency and the magnetic poles. The frequency is fixed, and the magnetic poles are determined by the structure of the motor, which cannot be changed in the course of operation, so it is quite difficult to adjust the speed of the ac motor. The variable speed of dc motor can be obtained from the hardness of its mechanical properties, which is the relationship between the torque of the motor and the rotational speed. Beta = dM/dn. Type in the beta is hardness, it is the differential ratio of torque and rotational speed, beta is hard characteristics, on the other hand is soft features, need speed can be as long as the soft characteristics of dc motor, series motor, when the load increases, its speed will come down.
- Q:What is the power of ac motor
- Two phase 380V ac motor: the rated power of the two phase 380V ac motor is the rated voltage by the rated voltage (s)
- Q:How to implement the start-stop of three-phase ac motor with the contactor?
- The contactor is divided into AC contactor (voltage AC) and DC contactor (DC), which is applied to power, distribution and electricity. A contactor is a term that refers to a magnetic field that is used by an industrial electrical current to generate a magnetic field, which makes the contact close to the control load.
- Q:Does ac motor use the upper hall sensor
- There are temperature sensors that can monitor winding temperature and avoid burning coils; There is a near switch or other sensor switch that can monitor the number of revolutions, or block the protection.
- Q:Direct current motor and ac motor, which is large, good, who invented
- The auster motor USES the principle of the magnetic effect of the current, and the principle is invented by the Danish physicist oster. He was born on August 14, 1777, in a family of pharmacists in rudjoin, langlang island. He was admitted to the university of Copenhagen in 1794 and a doctorate in 1799. He visited Germany and France in 1801-1803 and met many physicists and chemists. He was a professor of physics at the university of Copenhagen in 1806 and became executive secretary of the Danish royal society since 1815. In 1820, the royal society received the royal society award for the remarkable discovery of the magnetoelectric effect. In 1829, he was President of the Copenhagen institute of technology. He died in Copenhagen on March 9, 1851. He has studied physics, chemistry and philosophy too much. Due to the influence of Kant's philosophy and the natural philosophy of schelling, it is believed that natural forces can be transformed from one another, and the relationship between electricity and magnetism has been explored for a long time. In April 1820, the effect of the current on a magnetic needle, the magnetic effect of the current, was finally discovered. On July 21, the same year, he published his findings on the subject of an experiment on electroconflict in magnetic needles. This short paper to make Europe has had the enormous vibration physics, led to the emergence of a large number of experimental results, which has opened up a new field of physics ─ ─ electromagnetism. In 1934, the unit of strength of the magnetic field was named after "oster". In 1937 the American association of physics teachers set up the oster medal to reward physics teachers who contributed to physical teaching.
- Q:What is the effect of the ac motor on the connection of direct current
- In the home soybean milk machine circuit has a rectifier circuit, the motor is not a pure ac motor. The 48-v inverter means the conversion of 48V direct current to 220V ac. It's just that your inverter is driven by the emotional load, which is more than double the nominal power. Because domestic soybean milk machine work time is very short (beating), generally within 3 minutes, so the motor temperature rise is higher, can give it a try 2 48 v battery series up to 96 v try, however, for the first time must be careful have a look at the rise of temperature of the motor.
- Q:How does ac servo motor change direction?
- Change the servo motor parameters, such as the mitsubishi j3-a column, the PA_14 parameter
- Q:What is the difference between a brushless ac motor and a brushless dc motor?
- Single-phase ac motors and dc motors: the difference between rotor and stator single-phase dc motor is a permanent magnet (or equivalent of a permanent magnet, namely: fixed polarity does not change), and the single phase ac motor rotor is a magnet, also do not need electricity normally (cage). If a single phase ac is connected to a brushless dc machine, no power transfer is required. Other: no brush, brush the difference: the brushless motor is a special kind of dc motor, it USES built-in sensors electronic commutation on the method of the electronic commutator, brushless motor is mainly in order to eliminate the wear and tear of the brush, and brush contact generated noise. A brushless motor, coil and the commutator rotating, magnetic steel and carbon brush don't turn, is the direction of the coil current changes with the motor rotation phase switcher and brush. A brush motor has a carbon brush, a brushless motor without a carbon brush
- Q:According to the power of motor, how to select the contactor and switch?
- Must first determine the breaking current, the general low voltage bus bar breaking capacity above 500 kva transformer with 50 kA switches, small transformer low voltage busbar can use 12.5 kA and the breaking capacity of the switch. Secondly according to the current power calculation, and generally current = power/voltage/power factor, if the three-phase motor is divided by 1.732 (because of calculation is single-phase current), choose the rated current higher levels of switch and the contactor. Then select the corresponding tripping characteristics depending on the type of load switch (including tripping accessories), feeder switch will generally choose electromagnetic, should choose the thermomagnetic motor switch type, high perceptual load should choose high grade tripping characteristics of the switch.
- Q:Three-phase ac motor star row and delta connection?
- Three-phase squirrel-cage asynchronous motor adopts - delta Y step-down starting advantage: Y connection of the stator winding, the starting voltage for direct using delta connection, a third of the 1/3 of the starting current to delta connection, thus features good starting current, the circuit is simple, less investment. The drawback is that the torque is reduced to a third of the triangular method, and the torque characteristics are poor. So the line is suitable for light or no-load start. In addition, note that the consistency of the rotation direction should be noted when the y-delta joins
