Q:What are the advantages and disadvantages of the two approaches?
Hydraulic driver: The hydraulic system has a great power quality ratio, which is suitable for heavy load. Its advantages are high accuracy, high sensitivity and safety, such as the requirement for a voltage in some working area. The drawback is that it is costly and easy to leak
Q:In the instructions of the motor drive, the electrical current is cut off
B: yes. It's the same thing as an electric motor that doesn't have a brake. The step motor is the same as the normal motor once it is not controlled by the actuator. Controlled stepping motor does not rotate the rotor even if it does not rotate.
Q:Step motor drive, static current setting, what is the difference between setting ON or OFF?
OFF state can reduce electrical heating, but "brake" function is not strong, the motor rotation shaft torque under the action of outside the possibility of larger, severe cases can lead to Angle control error; ON state electrical opportunity heat, the temperature increase is permitted range. The "brake" effect is better than the former, which is suitable for high precision Angle control.
Q:What is the communication servo motor driver and how it works
Permanent magnet ac servo motor Since the 1980 s, with the integrated circuit, power electronic technology and the development of ac variable speed drive technology, permanent magnet ac servo drive technology has the prominent development, all countries well-known electrical manufacturers have launched their own ac servo motor and servo drive series products and constantly improve and update. The ac servo system has become the main development direction of the modern high performance servo system, so that the original dc servo system faces the crisis of elimination. Since the 1990s, the world's commoditized ac servo system has been powered by a full-digital sine wave motor. The ac servo actuator is developing rapidly in the field of transmission. Comparing with dc servo motor, the main advantages are: There is no brush and commutator, so the work is reliable and requires low maintenance and maintenance. It is convenient to heat the heat of the stator winding. The inertia is small and easy to improve the speed of the system. It is adapted to the high speed torque. There is a smaller volume and weight under the same power.
Q:What is the relationship between the step motor running current and the subdivision driver setting
That's a five fold increase in accuracy. And current, the stepper motor has A rated current, such as A click of the rated current of 4 A, if you are in the drive selected above is 2.25 A, then the strength of the motor can't reach the moment of it, but you set it to 5 A, while the strength, fever also become bigger, but relative to the motor current this setting needs to set up according to actual situation. Low load low speed setting small current, while high load revs require large current. There's no mathematical formula that is set by the actual situation, right
Q:What does the servo drive encoder line number 2500ppr mean
Servo driver encoder line number 2500 PPR is refers to the incremental encoder within a week, a 2500 pulse, through the principle of phase difference of 90 ° AB2 can be dividing into 10000, 360 ° is divided into 360.
Q:The difference between drive motor and frequency converter drive motor
The converter drives the motor, which drives the variable frequency motor, or the converter drives the ordinary asynchronous motor. The converter itself can control the frequency conversion motor or asynchronous motor, or it can be controlled by an external control converter (analog voltage, analog current, communication). The frequency converter is driven by the frequency conversion motor, which can be controlled by the speed control. The servo actuator which requires precise positioning control is driven by the servo actuator, which drives the frequency conversion motor with the frequency control.
Q:Is there a brush dc motor driven and no brush dc motor driven?
1. The difference between It's very different to have brushes and brushes. It's a lot easier to have a brush, and you can transfer it to a dc voltage. Brushless words power power electronic devices are needed to open and shut off voltage, and the need to according to the rhythm of the judgment of rotor position switch, control requirements are complex. To put it bluntly, brushless dc is essentially a square wave ac motor. But the control of the small brushless motor has matured, and all the fans in the computer have no brushes.
Q:Does the servo motor drive need 3C certification
Do you do servo motor drives? Can you give me a general idea of how the servo motor works? Is mainly position control loop control principle, my personal guess is a shock process, which is in the process of target location high-speed concussion, don't know right? How do you do that? Control the servo motor in the target position fast forward and back? Please don't hesitate to give me a message. Thank you very much.
Q:How do you measure the output current of the step motor driver
A series of current in one phase of the continuous running of the machine can be seen in one phase. In the phase line, the resistance of a single one in the phase line is used to see the waveform on both ends of the resistance, and the maximum on the oscilloscope is the peak current. The current, which is marked on the attachment of the appliance, or the current that the manufacturer stipulates that the attachment of the appliance can be carried by the specified conditions. Rated current of the electric equipment refers to the benchmark environment temperature, under the condition of rated voltage, fever is less than the long-term fever allowed temperature is allowed by the maximum current for a long time. Environment temperature, allows for a long time, maximum current has a great influence, due to the installation position of environmental temperature and temperature is not necessarily the same benchmark environment, generally as a rule: when the electric equipment work when the ambient temperature is higher than 40 degrees Celsius (but no higher than 60 degrees Celsius), environmental temperature, every 1 degree increase suggested that reduce the rated current 1.8%; When the temperature of the working environment is below 40 degrees, the temperature of the environment decreases by one degree, the recommended increase of 0.5 percent of the current rate, but the maximum of 20 percent of the rated current. For example, a 1mm2 copper conductor is rated at approximately 11A (30 degrees).
