  • Manufacturing method of stepping motor control device for electric drying rack

    September 12, 2020

    Background technique: The electric drying racks on the market have a short air outlet and a fixed direction, so the drying efficiency is low; the electric drying racks have a small blowing range, and the wind direction blown by the fan may not completely blow to the clothes, causing waste. Technical realization elements: The new technical problem is to provide an electric drying rack stepping motor control device applied to the air outlet of the electric drying rack, which can make the wind blown by the fan of the electric drying rack completely blow toward the clothes and improve the drying efficiency. The new type of electric drying rack stepping motor control device includes an electric drying rack body and a connecting rod, a fan, and a signal module for receiving remote control signals, and controlling the fan to turn on according to the remote control signal, and at the same time controlling the stepping motor to rotate and set the angle, Make the cut surface of the fan windshield just tangent to the MCU controller on the edge of the conjoined drying rod; the fan windshield is a double-open windshield, including a left windshield and a right windshield, and is set in the direction of the clothes dryer body The central position on one side of the connecting rod. The stepping motor of the electric drying rack controls the rotation of the wind deflector of the fan through a gear set to control the opening angle of the air guide opening of the fan; the gear set includes a first driving wheel and a second driving wheel that are engaged with each other. The meshing first driven wheel and the second driven wheel meshing with the second driving wheel; the center of the first drivin

  • Technical principle and test method of high-speed dome camera

    September 12, 2020

    The structure and principle of high-speed dome camera The high-speed dome camera is a highly integrated product that integrates the pan-tilt system, communication system, and camera system. The pan-tilt system refers to the driving part of the rotation, and the communication system refers to the control of the motor and the image and signal In the processing part, the camera system refers to the all-in-one movement. Between several major systems, the main control core CPU and power supply are connected horizontally. The power supply part is powered by the major systems. In many places, diodes, triodes and other micro-current power supply are used, and the core CPU is the basis for the normal operation of all functions. The principle of the high-speed dome camera is roughly what is mentioned above, and specifically, the high-speed dome camera adopts "precision differential high-speed dome camera stepping motor" to realize the fast and accurate positioning and rotation of the high-speed dome. All of this is achieved through instructions issued by the CPU. Then write the image of the camera and the functions of the camera into the CPU of the high-speed dome. When controlling the PTZ, the image can be transmitted, and many functions of the camera, such as white balance, shutter, aperture, zoom, and focus, can be transferred. And other functions can be controlled at the same time. General high-speed dome cameras are divided into the center part, the shell part and the accessories part. Any manufacturer`s high-speed dome has a sphere center part that uses a frame to unify the package all-in-one machine core, control decoding motherboard and motor pan/tilt system, and then the sphere center part and the shell are connected with screws or other methods. The center of the sphere is the

  • Summary of commonly used calculation formulas for stepper motors

    September 12, 2020

    1. Step angle: Each time the stator winding of the stepper motor changes its power state, the angle at which the rotor turns is called the step angle. The more the number of rotor teeth, the smaller the step angle; the more the stator phases, the smaller the step angle; the more the beat of the energization mode, the smaller the step angle. Step angle θ=360°/(number of rotor teeth×number of running beats). The step angle of the motor indicates the angle of rotation of the motor every time the control system sends a pulse signal. In other words, the angle that the rotor rotates for each input pulse electric signal is called the step angle, which is represented by θ. Take a conventional two-phase and four-phase motor with a 50-tooth rotor as an example. The step angle is θ=360 degrees/(50×4)=1.8 degrees (commonly known as full step) in four-beat operation, and the step angle is θ=360 degrees/(50×8)=0.9 degrees in eight-beat operation. Half step). Extended information The stepping motor has a fixed resolution. For example, a stepping motor with a resolution of 24 steps per revolution has a step angle of 15°. The advantages of using a small step angle to complete a certain incremental movement in several steps are: the amount of overshoot during operation is small, the oscillation is not obvious, and the accuracy is high. When selecting, the accuracy and speed requirements of the system should be weighed. The common ones are 3°/1.5°, 1.5°/0.75°, 3.6°/1.8°. For example, for a stepping motor (small motor) with a step angle of 1.8 degrees, the number of pulse

  • What are the characteristics of stepper motors?

    September 12, 2020

    (1) When the stepper motor is in operation, pulse signals are applied to the windings of each phase in turn in a certain order (the ring distributor in the drive controls the winding on and off). (2) Even if it is the same stepping motor, when using different drive schemes, its torque-frequency characteristics are quite different. (3) The highest temperature allowed on the surface of the stepper motor: If the temperature of the stepper motor is too high, it will demagnetize the magnetic material of the motor, and then cause the torque to drop and even lose step. Therefore, the highest temperature allowed on the surface of the motor should depend on the different magnetic materials of the motor. Generally speaking, the demagnetization point of magnetic materials is above 130 degrees Celsius, and some even up to 200 degrees Celsius, so the surface temperature of the stepper motor is completely normal at 80-90 degrees Celsius. (4) The stepper motor has no stacking errors: the accuracy of the general stepper motor is three to five percent of the actual step angle, and it does not accumulate. (5) The torque of the stepper motor will decrease with the increase of the speed: when the stepper motor rolls, the inductance of each phase winding of the motor will form a back electromotive force; the higher the frequency, the greater the back electromotive force. Under its effect, the phase current of the motor decreases as the frequency (or speed) increases, and then the torque decreases. (6) The stepper motor is different from other motors. Its nominal extra voltage and extra current are only reference values; and because the stepper motor is powered by a pulse method, the power supply voltage is its highest voltage, not the average voltage. The incoming motor can work beyond its rated value range. But the selection should not violate the rated value too far. (7) When the offline signal F
