describe
The commonly used stepper motors now include reactive stepper motors (VR), permanent magnet stepper motors (PM), hybrid stepper motors (HB), and single-phase stepper motors
Input motor, etc.
The reactive stepper motor uses high magnetic conductivity materials to form a toothed rotor and stator, with a simple structure, low production cost, and a relatively small step angle
It is three-phase and can achieve high torque output, with a step angle of generally 1.5 degrees, but with noise
And the vibration is very high. The rotor magnet of a reactive stepper motor is made of soft magnetic material, and there are multiphase excitation windings on the stator, which generate torque by utilizing changes in magnetic conductivity
The dynamic performance is relatively poor.
The rotor of a permanent magnet stepper motor adopts a cylindrical permanent magnet with multiple magnetic poles, and is equipped with a toothed stator on the outer side. Generate by the attraction and repulsion forces between the rotor and stator.
Rotating, it has high output and good dynamic performance, but the step angle is generally relatively high
Big. It is generally two-phase, with small torque and volume, and a step angle of 7.5 degrees or 15 degrees.
Hybrid stepper motor refers to a hybrid of permanent magnet and reactive advantages. It is further divided into two phases and five phases: the two phase step angle is generally 1.8 degrees, while the five phase step angle
It is generally 0.72 degrees. This type of stepper motor is the most widely used, which is PM and
The composite product of VR uses a toothed dilute ten permanent magnet material as the rotor, and a toothed protrusion structure as the stator. This type of motor combines both reactive and permanent magnet types
Advantages: small step angle, high output, good dynamic performance, making it one of the best
Class stepper motors are commonly used in computer related equipment.
PLC
(1)The development from on-off control to sequential control and computational processing is from bottom to top.
(2)Logic control,timing control,counting control,step(sequence)control,continuous PID control,data control-PLC has multiple functions such as data processing ability,communication,and networking.
(3)A single PC can be used as the master station,and multiple PLCs of the same type can be used as slaves.
(4)It is also possible to have one PLC as the master station and multiple PLCs of the same type as the slave stations,forming a PLC network.The convenience of using a PC as the main station is that when users program,they do not need to know the communication protocol,as long as they write it in the format specified in the manual.
(5)The PLC network can serve as both an independent DCS/TDCS and a subsystem of DCS/TDCS.
(6)Mainly used for sequential control in industrial processes,the new PLC also has closed-loop control function.
DCS Distributed Control System DCS and Distributed Control System TDCS are monitoring technologies that integrate 4C (Communication, Computer, Control, CRT) technology, and are the fourth generation process control systems. It has the advantages of advanced control formulas, high accuracy, and fast response speed in computer control systems, as well as the requirements for safe, reliable, and convenient maintenance of instrument control systems.
