An electric motor is a rotary electric machine that converts electrical energy into mechanical energy.How does an electric motor work physics. It mainly consists of an electromagnet winding or distributed stator winding for generating a magnetic field and a rotating armature or rotor. How does an electric motor work physics.Under the action of the rotating magnetic field of the stator winding, it has a current passing through the effective side of the stator winding and is rotated by the action of the magnetic field.

According to the principle of motor reversibility, if the motor does not change its structure, the motor is used as a motor and can also be used as a generator.How does an electric motor work physics. It is a machine that converts electrical energy into mechanical energy. Usually, the work part of the motor is rotated. This type of motor is called a rotor motor.How does an electric motor work physics. It is also called a linear motor.
The most widely used of various motors is an AC asynchronous motor (also known as an induction motor).How does an electric motor work physics. It is easy to use, reliable in operation, low in price, and firm in structure, but with low power factor and difficult speed regulation. Synchronous motors are commonly used in high-capacity, low-speed power machines (see Synchronous Motors).How does an electric motor work physics. The synchronous motor not only has a high power factor, but its speed is independent of the load and is determined only by the grid frequency.

The work is more stable. DC motors are often used where wide-range speed regulation is required.How does an electric motor work physics. However, it has a commutator, which is complicated in structure, expensive, difficult to maintain, and unsuitable for harsh environments. How does an electric motor work physics.After the 1970s, with the development of power electronics technology, the speed control technology of AC motors has gradually matured, and the price of equipment has been decreasing, and it has begun to be applied.

(1) Drive gear and driven gear.  The list of gearbox manufacturing companies.The input shaft can be understood as being connected to the clutch and rotating under the driving of the engine. The gear fixed on the input shaft rotates synchronously. The gear is called the driving gear, and the gear connected to the output shaft is forced to rotate. This gear is called a driven gear.
(2) Transmission ratio i. The list of gearbox manufacturing companies.The ratio of the number of teeth of the driven gear to the number of teeth of the driving gear is defined as the gear ratio.

When the relationship between the number of teeth of the driven gear and the number of teeth of the driving gear changes, the transmission ratio i changes, and under the condition that the engine speed does not change, the output shaft speed change, that is, the wheel speed changes. The list of gearbox manufacturing companies.A pair of intermeshing gears does not change in the number of teeth used, so its gear ratio is fixed. If a plurality of gears of different numbers of teeth are mounted on the input shaft and the corresponding number of teeth on the output shaft is also a variable gear meshing, a set of stepped transmissions having different gear ratios i can be obtained.The list of gearbox manufacturing companies. The car transmission is based on this basic principle to achieve shifting shifting.
(3) Forward gear, a gear that can drive the car forward. Reverse gear, which can make the car reverse the driving position. In the neutral position, the gears in the transmission are not in the working position. The list of gearbox manufacturing companies.At this time, after the engine power is input to the input shaft, it is no longer transmitted to the output shaft.
(4) Direct file. The engine power is transmitted through any gear in the transmission, but the gear output directly through the transmission input shaft and the output shaft directly connected thereto is called direct gear.The list of gearbox manufacturing companies. The direct gear ratio is 1.

(5) Overspeed gear. That is, the output shaft speed is higher than the input shaft speed.
(6) Number of files. Refers to the number of gear positions in a stepped gear transmission. The number of gears in common gear transmissions is four to five, and the three-speed transmission is rare. The list of gearbox manufacturing companies.The more the number of gears, the better the car's adaptability to driving conditions, and the lower the fuel consumption, but the more complicated the transmission transmission mechanism and the operating mechanism, the more difficult it is to operate and the higher the cost.
(7) Low grade, high grade. In the gear position of the transmission, the small number of gears is called low gear, the smaller the gear, the larger the gear ratio, the greater the traction, and the lower the speed.The list of gearbox manufacturing companies. For example, the gear ratio of the first gear is the largest in the forward gear, the lowest speed and the highest traction. The digital gear is called high-grade, the larger the number, the smaller the gear ratio, the smaller the traction, but the higher the speed.

(8) Shifting. The shifting process of the transmission to complete the gear ratio is called shifting. The list of gearbox manufacturing companies.The shifting of the sleeve is performed by integrating with the gear, and the engaging ring ring on the flank and the engaging sleeve are engaged (or separated) to realize a gear ratio change called a sleeve shift. The synchronizer shifts and uses the synchronizer to shift gears. The list of gearbox manufacturing companies.The shifting not only has no impact and noise on the engaging teeth but also a short shifting time.
(9) Jumping. The list of gearbox manufacturing companies.During the running of the car, due to the wear and vibration of the engaging teeth, the clutch sleeve and the engaging ring gear are separated to make the transmission in a neutral state.

The difference between single stage and two stage gearbox

1, structurally different

The three-axle transmission has three shafts, and the two-shaft transmission has two shafts; the input shaft and the output shaft of the two-shaft transmission are not on the same axis, and the two shafts are the first shaft (input shaft) and the second shaft (output) axis).

The first axis is the driven shaft of the clutch, the second shaft is the main shaft of the main reducer, and the single-stage shifting is used by the car due to its small size. The difference between single stage and two stage gearbox.Unlike the two-shaft transmission, the input shaft and the output shaft of the three-shaft transmission are on the same axis, one more intermediate shaft than the two-shaft transmission, and is a two-stage shift. Due to the large torque generated, the body is large and mostly used by heavy-duty vehicles.

The lubrication system of the gearbox is very important for the normal operation of the gearbox.  The design and analysis of a two stage reduction gearbox.The large wind turbine gearbox must be equipped with a reliable forced lubrication system to inject the oil to the gear meshing area and bearings.  The design and analysis of a two stage reduction gearbox.In the cause of the failure of the gearbox, the lack of lubrication accounted for more than half.  The design and analysis of a two stage reduction gearbox.Lubricating oil temperature is related to component fatigue and overall system life. Generally speaking, the maximum oil temperature of the gearbox should not exceed 80 °C during normal operation, and the temperature difference between different bearings should not exceed 15 °C. The design and analysis of a two stage reduction gearbox.When the oil temperature is higher than 65 °C, the cooling system starts to work; when the oil temperature is lower than 10 °C, the oil should be heated to the predetermined temperature and then turned on.
