Panasonic DC servo A4 series of products in the market for many years, and now A5 product out, will replace the A4 series, vigorously cooperation with Matsushita Electric, Matsushita Electric has overall responsibility for A5, A4 series products in China, sales and technical services for China automation industry to make its own contribution. Automatic control device is used to perform micro-motor components. Also known as the implementation of an electric motor. Its function is to convert electrical signals into angular displacement or angular velocity of the shaft. Servo motor points of AC and DC types. AC servo motor works with the same AC induction motor. There are two phases in the stator spatially shifted 90 ° electrical angle of the field winding and the control winding WcoWf Wf connected a constant AC voltage, the use of AC voltage or phase change on Wc applied to achieve the purpose of controlling the motor operation. AC servo motor with a stable, controllable, fast response, high sensitivity and mechanical properties and regulation characteristics of the nonlinear index stringent (requirements were less than 10% to 15% and less than 15% to 25%) and so on. DC servo motor works with the same general DC motor. Motor rotational speed n as where E is an armature counter electromotive force; K is a constant; j is the flux per pole; Ua, Ia is the armature voltage and armature current; Ra is the armature resistance. Ua change or alter φ, can control DC servo motor speed, but the general method of controlling the armature voltage. In the permanent magnet DC servo motor, the field winding is replaced by permanent magnet flux φ constant. DC servo motor has good linear regulation characteristics and fast response time. Servo Motor Servo: from the Greek word "slave" means. People want "servos" When a handy tool to tame obedience control requirements and operating signal. Before the signal came, the rotor is stationary; after the signal came, rotor immediately; when the signal disappears, the rotor can immediately own stall. Because of its "servo" performance, hence the name. DC servo motors are generally divided into AC servo for servo and DC servo motor Advantages: accurate speed control, torque-speed characteristics hard, the principle is simple, easy to use, the price advantage Disadvantages: brush commutation, speed limits, additional resistance, generate wear particles (for clean room) for AC servo motor Pros: good speed control characteristics throughout the region to achieve a smooth speed control, almost no oscillation; high efficiency, more than 90%, no heat; high-speed control; high precision Position control (depending on what kind of encoder); rated operating area, achieve constant torque; low noise; no brushes to wear, maintenance-free; no wear particles, no spark, suitable for clean rooms, easy to violent environment inertia low; Panasonic MINAS A4 SERIES Panasonic digital AC servo system Panasonic AC servo AC servo motor output power is generally 0.1-100 W, the power frequency 50Hz, 400Hz and other.

Miniaturization design 1) miniaturized, compared with the past, by volume 75%, by weight of the drive optimum thermal analysis 80% 2 ) using thin steel mold punching new technology to significantly reduce iron loss, shortening the length of the motor (in the past 70%) reduction drive model, easy stocking and maintenance using current classification method, a variety of motor drive adapter, automatic identification increasing the motor type, adapt more occasions a) increasing the speed of ultra-small inertia motors, servo motors to adapt more occasions 2) for the Chinese OEM customers, an increase of low inertia motor power increases Wire-saving incremental encoder 5 lines; Absolute Power Line 7 ability to adapt to China to improve the main circuit design reference China Power Grid, the specially designed single-phase 200V, single / three-phase 200V drives use a simple, high performance comes with the operator panel, convenient parameter adjustment, status monitoring, and troubleshooting tips analysis, automatic adjustment function enables intelligent and powerful professional manner, complex debugging process is easy to complete high speed and high speed response frequency response up to 1kHz; high-performance mechanical adaptability can receive up to 2Mpps pulse command built-instantaneous speed observer, fast high resolution detection of ultra-low vibration motor speed 1) adaptive filter, can automatically adjust the notch filter frequency depending on the mechanical resonance frequency 2) two manual notch filter to suppress mechanical resonance 3) two-channel vibration suppression filters, mechanical distal vibration suppression corresponding global environmental concerns ROHS directive, the use of lead-free solder. Edit this paragraph 1.SERVO works mainly on the pulse to locate, basically can be understood, the servo motor receives a pulse, will be rotated an angle corresponding to the pulse, in order to achieve displacement, because, pulsing the servo motor itself has the function of each of the servo motor so that a rotation angle corresponding to the number of pulses will be issued, so that the servo motor, and a pulse forming acceptable echo, or called closed loop, this way, the system will know how many pulses sent to the servo motor, while the number of pulses received back, so that we can very accurately control the rotation of the motor in order to achieve accurate positioning can be achieved 0.001mm. 2. AC servo motor is a brushless motor, divided into synchronous and asynchronous motors, the current motion control generally use synchronous motors, large power range it can do a lot of power. Large inertia, the maximum rotational speed is low, and with the power increases rapidly decreased. Therefore suitable for low speed applications running smoothly. 3. The servo motor is a permanent magnet rotor inside the drive control U / V / W three-phase power to form an electromagnetic field, the rotor rotates in the role of the magnetic field, while the motor comes with encoder feedback signal to the drive, the drive based on feedback is compared with a target value, adjusting the angle of rotation of the rotor. Depends on the accuracy of the servo motor encoder accuracy (number of lines). Edit the main advantages of this paragraph since the 1980s, along with integrated circuits, power electronics and variable speed AC drive technology development, permanent magnet AC servo drive technology has outstanding development, countries famous electrical manufacturers have launched their own exchange servo motor and servo drive products and continue to improve and update. AC servo system has become the main direction of development of contemporary high-performance servo system, so that the original DC servo be forced out of the crisis. 90 years later, the world has been commercialized AC servo motor servo system is the use of digital control sine wave drive. AC servo drive the rapid development in the field of transmission. Permanent magnet AC servo motor with DC servo motor comparison, the main advantages are: ⑴ without brush and commutator, so reliable, low-maintenance and maintenance requirements. ⑵ stator windings heat more convenient. ⑶ inertia is small, easy to improve the system fast. ⑷ adapted to high-speed high torque working condition. Smaller size and weight ⑸ under the same power. Edit this paragraph since the history of the German MANNESMANN Rexroth Indramat's division at the 1978 Hanover Trade Fair officially launched MAC permanent magnet AC servo motor and drive system, which marks this new generation of AC servo technology has entered the practical stage. To the late 1980s, companies already have a complete range of products. Entire servo market have turned the AC system. Early simulation system deficiencies such as zero-drift, interference, reliability, accuracy and flexibility, etc., still can not fully meet the requirements of motion control in recent years with the microprocessor, the new digital signal processor (DSP) applications the emergence of the digital control system, the control section can be completely carried out by the software, called 摪 hazy or Tuan Jing 瘮 only fresh coarse hempen fabric, valiant only 瘮 of permanent magnet AC servo system. So far, the performance of the electric servo system mostly uses a permanent magnet synchronous AC servo motor control driver use more quickly and accurately locate the position of all-digital servo system. Typical manufacturers such as Siemens of Germany, the United States and Japan, Kollmorgen companies such as Panasonic and Yaskawa. Japan's Matsushita Electric Works has launched a small AC servo motors and drives, including large inertia series for CNC machine tools, the inertia of the series for the robot (maximum speed of 3000r / min, the torque of 0.016 ~ 0.16Nm). Also launched a series of small inertia. 1990s, has launched a new series of A4 and A5 series. Drive from the old series of rectangular wave, sine 8051 control to drive, 80C, 154CPU and gate array chip control, torque ripple from 24% down to 7%, and increased reliability. Thus, only the formation of the eight series (power range of 0.05 ~ 6kW) more complete system with a few years to meet the working machinery, transportation agencies, welding robots, assembly robots, electronic components, machine tools, printing presses, high-speed winding machine, winding machine different needs.
