Geared motorsIt's called a gear motor.
They are all modular, and the output torque becomes larger at the same time, 6 poles (output synchronous speed 1000rpm), 8 poles (output synchronous speed 750rpm), so it is through the gear mechanism or other mechanisms (such as cycloid.
The speed of the motor is reduced, and the output speed or torque of the motor can not meet the actual requirements, of which the 4-pole motor is the most commonly used, because the speed of the equipment is generally small, the motor, the more advanced the number of poles, the more expensive it is, the common motor is 4 poles (output synchronous speed 1500rpm), which is a combination of the reducer and the motor.
The reducer is a transmission.
The principle is to mesh the large gear on the output shaft through the gears with fewer teeth on the input shaft of the reducer to achieve the purpose of deceleration; The ratio of the number of teeth of the large and small gears is the transmission ratio.
The reducer is an independent component composed of gear transmission, worm transmission and gear-worm transmission enclosed in a rigid shell, and is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery. The reducer can be divided into single-stage and multi-stage reducer according to the number of transmission stages, and the shape of the factory wheel can be divided into cylindrical gear reducer, bevel gear reducer and conical cylindrical tooth guide wheel reducer; According to the arrangement of the transmission, it can be divided into type, shunt type and co-shaft reducer.

The geared motor is the combination of the reducer and the motor. There is a square or other shape of iron bump at the end of the output shaft of the motor, which is the reducer. This kind of motor is suitable for the situation where the motor does not need to rotate forward and reverse frequently, and the load speed is low and the torque is large.
This is done to reduce the capacity of the motor and save costs.

The main difference between a geared motor and a drive motor is in terms of function, the former has both the function of deceleration and the ability to drive, while the latter only has the function of driving and no deceleration.
1. Geared motor.
Geared motor refers to the integration of reducer and motor (motor), which can also be called gear motor or gear motor or reduction gearbox; Usually by the reducer manufacturer, after the integration and assembly, and the motor is supplied as a complete set (for example, Zhaowei Electromechanical focuses on the production of geared motors); The main function is to reduce the speed, inertia, and increase the torque of mechanical transmission products, including ordinary motors; According to the transmission structure, the geared motor is divided into gear reducer, planetary reducer, DC reducer, worm gear reducer and other products.
2. a drive motor.
Electric machinery (commonly known as "motor") refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. In the circuit, it is represented by the letter M (formerly D).
Its main function is to generate transmission torque, as a power source for electrical appliances or various machinery. Generators are denoted by the letter G in the circuit. Its main role is to utilize electrical energy to convert into mechanical energy.
The motor is the power source, which is purchased by the reducer manufacturer, and is usually used with the reducer to form a combined geared motor, which is used in all walks of life; The motor can be used in different industries according to the use, power and size, such as small to electronic locks, to the steel and mining industries.

The differences are as follows: 1. The principle is different, the geared motor is the integration of the reducer and the motor (motor). The drive motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction.
2. The main role of the geared motor is to reduce the speed, inertia, and increase the torque of mechanical transmission products; The main function of the drive motor is to convert electrical energy into mechanical energy.

Not a concept.
The reduction ratio, that is, the transmission ratio of the deceleration device, is a kind of transmission ratio, which refers to the ratio of the instantaneous input speed to the output speed in the deceleration mechanism, with symbols"i"Denote.
1. Define the calculation method: reduction ratio = input speed output speed. Reduction ratio.
2. General calculation method: reduction ratio = use torque 9550 motor power motor power input speed use coefficient.
3. Gear train calculation method: reduction ratio = number of driven gear teeth number of driving gear teeth (if it is a multi-stage gear reduction, then the number of driven gear teeth of a pair of gear sets that are meshed together The number of driving gear teeth, and then multiply the results obtained.
4. Calculation method of reduction ratio of belt, chain and friction wheel: reduction ratio = diameter of driven wheel and diameter of driving wheel.
Compared with ordinary motors, high-temperature motors adopt advanced design technology, made of high-temperature resistant insulating materials, it can ensure the safe operation of the motor in a high-temperature environment, no aging, no burning, although there are not many domestic enterprises producing high-temperature motors, but the application range of high-temperature motors is wide, and the market prospect is promising. Its motor performance is designed according to the characteristics of fan pump loads, which can save energy and insulate structure. The use of reinforced insulation, can be long-term in the high temperature and high humidity wood precipitation water vapor atmosphere environment continuous forward and reverse cycle operation, so as to ensure reliable insulation and improve the service life, the motor adopts keyway type and threaded type, which is convenient for the loading and unloading of fan impellers; In order to improve its own waterproof steam and wood dust resistance. >>>More
