In order to enhance everyone's understanding of motor, let more people understand the relevant technical principles. This paper will introduce the micro control motor and the full disc motor.

1、 Micro control motor

Micro control motor is a kind of small power rotary motor with specific functions.
 
The control motor is used as executive element, detecting element and calculating element in control system. From the working principle, there is no essential difference between micro control motor and ordinary motor, but the function is different. The common motor has high power, which focuses on the starting, running and braking performance indexes of the motor, while the output power of the control motor is small, which focuses on the control accuracy, response speed and operation reliability of the motor. At present, there are many kinds of micro controlled motors produced at home and abroad,
 
The following describes the basic working principle and use characteristics of several commonly used micro controlled motors.
 
Single phase asynchronous motor is a kind of motor powered by 220 V single-phase AC power supply. It is suitable for small industrial equipment and household appliances with only single-phase power.
 
Tachogenerator is a kind of micro generator for measuring speed. It transforms the input mechanical speed into voltage signal output, and requires that the output voltage signal is proportional to the speed. Tachogenerator is divided into DC tachogenerator and AC tachogenerator.
 
The function of servo motor is to convert the input voltage signal into angular displacement or angular velocity output on the shaft, and its speed and direction change with the size and direction of input voltage signal. In the servo system, it is also called the motor control element. For example, in a CNC lathe, the cutter is driven by a servo motor, and he will drag the cutter to cut the device according to the shape of the given target. In the early stage, the output power of servo motor was small, and the power range was generally 0.1-100 watts. However, at present, the development of servo technology is very fast, and several thousand watt high-power servo motors appear one after another.
 
The stepper converts the pulse signal into angular displacement or linear displacement. Main requirements: sensitive, accurate, light weight, small size, reliable operation, low power consumption, etc.
 
The synchro is used for angle transmission, indication or transformation in automatic control system. Usually, two or more same synchros are used together. There are two types of synchro, control type and torque type, which have different uses. Torque type synchro is used for remote angle indication, while controlled synchro can convert angle into electrical signal.
 
The structure of synchro is divided into two parts: stator and rotor, stator, rotor, damping winding, brush, terminal and slip ring.
 
In order to remove the brush, the armature of Brushless DC motor is placed on the stator, and the rotor is made into permanent magnet. This structure is just the opposite of the ordinary DC motor. However, even if this change is not enough, because the armature on the stator can only produce constant magnetic field after DC, the motor still can not rotate. In order to make the motor rotate, it is necessary to make the stator armature windings of each phase change continuously. In this way, the stator magnetic field can be constantly changed with the position of the rotor, so that the stator magnetic field and the permanent magnetic field of the rotor always keep a left-right space angle, and produce torque to drive the rotor to rotate.

2、 Full disc motor

Full plate motor refers to a long-life, high torque motor, which can meet any complex road conditions. The motor combines the driving wheel and motor into a whole, which not only has a beautiful appearance, but also has a torque of more than three times that of the ordinary brushless motor, and its service life is more than twice that of the ordinary brushless motor. It is the best choice for consumers who pursue fashion and power.
 
Full disk motor uses new permanent magnet material, which is the largest magnetic energy per unit volume among all magnetic materials. It has a magnetic flux of 320, 7 driving channels, 12 transmission combinations, 56 magnetic energy series and 3 CPV energy-saving control modules. The torque of the motor is increased by 30%, the energy consumption is reduced by 10%, and the continuous mileage is increased by 1 / 3, so that the power is stronger and the driving range is longer, It realizes the perfect combination of super power and ultra-low energy consumption of magnetic energy motor, and solves the technical problems of large power and short mileage of traditional magnetic energy motor.
