1. How to choose the servo motor and stepper motor correctly?
Mainly depending on the specific application, it is simple to determine: the nature of the load (such as horizontal or vertical load), torque, inertia, speed, accuracy, acceleration and deceleration requirements, upper control requirements (such as port interface and communication Aspect requirements), the main control method is position, torque or speed mode. Whether the power supply is DC or AC, or battery powered, voltage range. This is used to determine the model of the motor and the associated drive or controller.
2, how to use stepper motor driver
Depending on the current of the motor, a driver greater than or equal to this current is used. A subdivided drive can be used if low vibration or high precision is required. For high torque motors, use high voltage drives as much as possible to achieve good high speed performance.
What is the difference between 3, 2 phase and 5 phase stepper motors? How to choose?
The 2-phase motor has a low cost, but the vibration is high at low speeds and the torque at high speed is fast. The 5-phase motor has less vibration and high-speed performance, which is 30~50% higher than that of the 2-phase motor. It can replace the servo motor in some occasions.
4. I want to directly control the servo motor by means of communication. Is it OK?
Yes, it is more convenient, just a speed issue, for applications that require less response speed. If fast response control parameters are required, it is best to use a servo motion control card. Generally, it has a DSP and a high-speed logic processing circuit to achieve high-speed and high-precision motion control. Such as S acceleration, multi-axis interpolation, and so on.
5. Is it good to supply the stepping and DC motor system with a switching power supply?
Generally, it is best not to use a large torque motor, unless a switching power supply that is more than twice as large as the required power is used. Because the motor works as a large inductive load, it will form an instantaneous high voltage on the power supply end. The overload performance of the switching power supply is not good, it will protect the shutdown, and its precision voltage regulation performance is not needed, and sometimes it may cause damage to the switching power supply and the driver. A DC power supply that can be transformed with a conventional toroidal or R-type transformer.
6. Can the servo motor's code disc part be disassembled?
It is forbidden to disassemble, because the quartz plate in the code wheel is easy to break, and after entering the dust, the life and accuracy will not be guaranteed, and professional maintenance is required.
7. Can the stepper motor and servo motor be disassembled for repair or modification?
No, it is best to let the manufacturer do it. After disassembling, there is no professional equipment and it is difficult to install it back to the original. The gap between the stator and the stator of the motor cannot be guaranteed. The performance of the magnetic steel material is destroyed, and even the loss of magnetism, the motor torque is greatly reduced.
8. Can I use a domestic drive or motor with a foreign high-quality motor or driver?
In principle, it is ok, but it is necessary to understand the technical parameters of the motor before it can be used. Otherwise, it will greatly reduce the effect and even affect the long-term operation and longevity. It is best to consult with the supplier before deciding.
9. Is it safe to drive the motor with a DC supply voltage greater than the rated voltage?
Normally this is not a problem as long as the motor is running within the set speed and current limits. Since the motor speed is proportional to the motor line voltage, selecting a power supply voltage does not cause overspeed, but a driver failure may occur.
In addition, it must be ensured that the motor meets the minimum inductance requirements of the drive and that the set current limit is less than or equal to the rated current of the motor. In fact, it is good if you can make the motor run slower (lower than the rated voltage) in the device you are designing. Operating at a lower voltage (and therefore a lower speed) will result in less brush bounce, and less wear on the brush commutator, lower current consumption and longer motor life. On the other hand, if the motor size and performance requirements require additional torque and speed, over-driving the motor is also possible, but at the expense of the product's useful life.
10. Why can't the reducer match the motor exactly at the standard torque point?
If the maximum continuous torque through the reducer generated by the motor is taken into account, many reduction ratios will far exceed the torque level of the reducer.
If we are designing each reducer to match the full torque, there will be too many combinations of internal gears (larger and more material). This will make the product price high and violate the "high performance, small size" principle of the product.
11, how do I choose to use a planetary reducer or a spur gear reducer?
Planetary reducers are generally used when high torque is required in a limited space, ie small volume and large torque, and its reliability and life are better than spur gear reducers. Spur gear reducers are used for lower current consumption, low noise and high efficiency and low cost applications.
12, What is the duty cycle?
The duty cycle is the ratio of the working time / working time + non-working time of the motor during each working cycle. If the load rate is low, the motor is allowed to run at 3 times continuous current for a short period of time, resulting in more force than rated continuous operation.
13. Can the drive circuit of a standard rotating motor be used for a linear motor?
Generally it is ok. You can use linear motors as rotating motors, such as linear stepper motors, brushed, brushless, and AC linear motors. Please consult the supplier for details.
14. Can the linear motor be installed vertically and do the up and down movement?
can. According to the user's request, we can add the slider slide balancing device or the rail brake brake when installing vertically.
15. What are the advantages of using a linear motor with a linear motor for a ball screw?
Since there is no mechanical connection between the stator and the mover, the backlash, wear, and jamming problems are eliminated, and the motion is smoother. It highlights the features of higher precision, high speed, high acceleration, fast response, smooth motion, high control precision, good reliability, compact size, low profile, long life and maintenance-free.
16, how to choose electric cylinders, slides, precision platform products? How is the cost calculated?
The key to selecting actuators is to see what kind of requirements you have for the motion parameters. You can determine the technical conditions such as specific motion parameters according to the application you need. These parameters should meet your actual needs, and must meet the application requirements. Leave room for it, and don't raise it too high, otherwise its cost may be several times that of a standard product. For example, if the 0.1mm accuracy is sufficient, do not choose a parameter of 0.01mm. Others such as load capacity, speed, etc. are also true.
Another selection recommendation for the user is that if it is not necessary, the three main parameters of push-pull or load-bearing, speed, and positioning accuracy are not required at the same time because the actuator is a high-precision and high-tech mechatronic product. In design and manufacture, we need to consider and select the corresponding motor, drive controller and feedback device from various aspects such as mechanical structure, electrical performance, material properties, materials and processing methods, as well as guide rails, screw rods and supports of different precision grades. The seat and other mechanical systems, to achieve the required overall motion parameters, can be described as a product that launches the whole body. Of course, if you have a demanding product, we can still meet it, but the cost will increase accordingly.
