The motor model is a code that is convenient for use

The motor model is a code that is convenient for use, design, manufacturing and other departments to conduct business contacts and simplify the description of product names, specifications, types, etc. in technical documents. The following introduces the meaning of the motor model and other information. 1. The composition and meaning of the motor model are composed of four sub-sequences, including the motor type code, motor characteristic code, design serial number, and excitation mode code. 1. The type code is a Chinese pinyin letter used to characterize various types of motors. For example: asynchronous motor Y synchronous motor T synchronous generator TF DC motor Z DC generator ZF2, the characteristic code is to characterize the performance, structure or use of the motor, and it is also expressed in Chinese Pinyin. For example: B is used for flameproof type, YT is used for YB axis flow fan, electromagnetic brake type, YEJ variable frequency speed control type, YVP, variable pole multi-speed type, YD crane, YZD, etc. 3. The design serial number refers to the order of the design of the motor product, which is represented by Arabic numerals. The design serial number is not marked for the first designed product, and the products derived from the series are marked in the order of design.


For example: Y2, YB24, and excitation code are represented by letters, S is the third harmonic, J is the thyristor, and X is the phase complex excitation. For example: Y2 160 M1 \u0026 ndash; 8 Y: Model, indicating asynchronous motor 2: design serial number, '2' represents the first time to improve the design of the product 160: center height, is the height from the axis center to the plane of the base M1: machine For the seat length specification, M is a medium size, of which the footnote '2' is the second specification of the M-type iron core, and the '2' type is longer than the '1' iron core. 8: Number of poles, '8' means an 8-pole motor. For example: Y 630-10 / 1180 Y means asynchronous motor 630 means power 630KW 10 pole, stator core outer diameter 1180MM. Second, the specification code mainly uses center height, machine base The length, core length, and number of poles are used to indicate the height of the center from the motor shaft to the bottom corner of the machine base. The motor can be divided into four types: large, medium, small, and miniature. The center height is H. 45mm ~ 71mm belongs to micro motor H 80mm ~ 315mm belongs to small motor H 355mm ~ 630mm belongs to medium-sized motor H 630mm or more belongs to large motor. 2. The length of the base is indicated by international universal letters: S--short Base M--Medium base L--Long base 3, the length of the iron core is represented by the Arabic numerals 1, 2, 3, and 4 from long to short. 4, the number of poles is divided into 2 poles, 4 poles, 6 poles, 8 poles Etc. III. The special environment code has the following provisions:


The special environment code is 'high' with the original G barge ('sea' with H) and 'outside' with W chemical to prevent 'corrosion' with F tropical with T wet tropical Use TH Dry heating belt TA. The supplementary code is only applicable to motors with supplementary requirements. Example: The motor code of the product model YB2-132S-4 H means: Y: product type code, indicating asynchronous motor B: product feature code , Indicates explosion-proof type 2: product design serial number, indicates the second design 132: motor center height, indicates that the distance from the axis to the ground is 132 fan motor mm S: length of the motor frame, expressed as a short frame 4: number of poles, indicates 4-pole motor H: special environmental code, which means a marine motor. Through the detailed introduction of the motor model above, I believe that we can know the type, characteristics, design serial number, motor specifications and the motor used by seeing the product model in the future. Environmental information.

The factory parameters of the motor generally include the parameters of the take-off frequency

If you still feel stuck or lost steps, adjust the acceleration and other parameters according to steps 10, 11, and 12. Generally, considering the drive capability of stepper motors, the friction of mechanical assembly, and the bearing capacity of mechanical parts, the high speeds of each axis can be modified in the manufacturer parameters to limit the high speeds of the three axes when the machine tool user actually uses them. Generally, for a machine tool consisting of a stepper motor system, the value is between 400 and 1000, and for a servo motor system, it can be set between 1000 and 5000. Reasonable selection of this parameter can improve processing efficiency and avoid low-speed sections with poor motion characteristics of stepper motors; however, if this parameter is selected too large, it will cause stuffiness, so be sure to leave margin. The unit is mm / s square. Take-off speed: This parameter corresponds to the take-off frequency of the stepper motor. Set the automatic fueling parameters (set smaller, Range hood motor factory such as refueling every 5 seconds) and observe whether the automatic fueling is correct. Generally speaking, for the users of mold machines, the pulse equivalent is 0.


If there is deviation, please check the type of pulse signal received by the stepper driver, and check whether the indirect line between the terminal board and the driver is wrong. 3. If the movement direction is correct, continue to return, otherwise stop, reset the direction of returning to the machine origin in the manufacturer parameters until all axes can return to the machine origin. You can use an intuitive method: use a sharp knife to point a point on the workpiece blank, set the point as the work origin, raise the Z axis, and then set the Z axis coordinate to 0; repeatedly move the machine tool, such as empty tool running A typical machining program (including three-axis linkage) can be paused or stopped during machining, and then returned to the workpiece origin, and the Z axis is slowly lowered to see if the tool tip matches the point on the blank. The larger this value is, the less time is spent in the acceleration and deceleration during the movement, and the higher the efficiency. For a two-phase stepping motor, the pulse equivalent calculation method is as follows: Pulse equivalent = lead screw pitch \u0026 divide; divide number \u0026 divide; 200. Determine if there are missing pulses. You can make a mark on any axis of the machine tool, set the coordinate of this point as the working zero point in the software, use the direct input command, jog or handwheel to make the axis travel a fixed distance, and use vernier calipers to measure the actual distance Whether it is related to the coordinate display distance in the software. The factory parameters of the motor generally include the parameters of the take-off frequency. Therefore, the setting parameter is better to refer to the factory parameters of the motor and then determine the actual measurement.


If abnormal conditions are found, lower the value and leave a 50% to 100% insurance margin. However, if the number of subdivisions is too high, it will affect the high feed rate. The so-called take-off frequency is the high frequency at which the stepping motor can start directly without acceleration. Verify that the setting values ​​of the electronic gear and pulse equivalent match. According to the installation positions of the three axis zero point sensors, set the parameters of returning to the machine origin in the manufacturer parameters. 7. In the setting process, start to set a little smaller, run for a period of time, repeat various typical exercises, pay attention to observation, if there is no abnormal situation, then gradually increase. The larger this value is, the greater the allowable speed of the machine when making circular motion.0005mm / P (at this time, the maximum feed speed is 4800mm / min); For users with low accuracy requirements, the pulse equivalent can be set larger, such as 0. 8. If abnormal conditions are found, lower the value and leave a 50% to 100% insurance margin. 4. In the setting process, start to set a little smaller, run for a period of time, repeat various typical linkage movements, pay attention to observation, if there is no abnormal situation, then gradually increase.001mm / P (at this time, the maximum feed speed is 9600mm / min) or 0. 5. If it is correct, set the automatic fueling parameters to the actual parameters.[Tag: title]

  1. Generally, the higher the number of subdivisions, the higher the control resolution. Single-axis acceleration: It is used to describe the acceleration and deceleration ability of a single feed axis, and the unit is mm / s square. It determines the high speed of the machine when making circular motions. When the settings are correct, you can run 'Back to Machine Origin' in the 'Operation' menu. Set the number of subdivisions of the stepper driver. Perform single axis return first. 2. However, after the machine tool is assembled, the value may change, and it will generally decrease, especially when doing load movement. For servo motor systems, it can be set between 400 and 1200. For heavy machines, this value is smaller. This index is determined by the physical characteristics of the machine, such as the mass of the moving part, the torque, resistance, and cutting load of the feed motor. 6. Generally, for stepping motors, the value is between 100 and 500. Curve acceleration: It is used to describe the acceleration and deceleration ability when multiple feed axes are linked. .002mm / P (at this time, the maximum feed rate is 19200mm / min) or 0
