    1. Products Overview

    Step motor is a motor that converts the electrical pulse signal into the corresponding angle displacement. For each of the pulse signal, the rotor rotates a certain angle accordingly, and the speed is proportional to the input pulses’ frequency. Therefore, step motor is also called pulse motor.

    The biggest difference between step motor compared to other control motors is that it receives digital control signals (pulses) and converts into angle displacement accordingly. Enter a pulse signal to get a specified position increment. Compared with the traditional DC control system, such a so-called incremental position control system, the stepper system complexity and cost are significantly reduced. The angular displacement of the stepping motor is strictly proportional to the number of input pulse, and it is synchronized with the pulse in time. Therefore, by controlling the pulse frequency and pulse quantity, the motor shaft speed, and position can be controlled precisely too.

    At the same time, Kaifull has solved many problems of traditional stepper drivers buy the latest patented technologies. There are many middle and high end customers globally, and they highly appreciate our stepper motor and drives very much.


    Although the stepper motor and its control technology are currently very mature, if not used properly, there may still be a situation of step loss, that is, position error etc. Here, we will analyze some problems and solutions.

    Losing pulses when changing direction leads to inaccurate positioning

    When changing direction, the pulse is lost, which means that it is accurate in any direction, but as soon as the direction is changed, errors accumulate, and the more times it is changed, the more biased it is.

    Solution: Generally, stepper drivers have certain requirements for direction and pulse signals. For example, the direction signal is determined a few microseconds before the first rising or falling edge of the pulse (different drivers have different requirements) arrives. Otherwise, there will be a pulse that runs in the opposite direction of the actual required direction. Finally, the problem will appear as it deviates more and more, with smaller subdivisions becoming more prominent. The main solution is to use software to change the logic of the pulse or add a delay.

    The initial speed is too high and the acceleration is too large, which sometimes causes stepping loss.

    Solution: Due to the characteristics of the stepper motor, the initial speed should not be too high, especially when the load inertia is large. It is recommended to have the initial speed below 1r/s, so that the impact is small. If the same acceleration is too large, it will also have a large impact on the system, which is simple overshoot

    Insufficient motor output torque

    Solution: Increase the motor current appropriately, increase the voltage of the progressive driver (pay attention to the optional driver), and choose a motor with higher torque.

    Environmental electromagnetic interference causes mis-operation of the controller or driver, resulting in inaccurate positioning.

    It is necessary to identify the source of disturbance and reduce its electromagnetic interference on the stepper system, such as increasing spatial distance, using shielded wires for signal lines, and ensuring good grounding of the controller or driver to block communication channels and improve its anti-interference ability.

    Solutions:

    • Replacing ordinary wires with double shielded wires, the signal lines in the system are separated from wires with high current or high voltage to reduce electromagnetic interference ability.
    • Filter out disturbance waves from the power grid using power filters, and add power filters to the input terminals of major electrical equipment under permissible conditions to reduce interference between devices within the system.
    • It is best to use photoelectric blocking devices for signal transmission between devices. If conditions permit, pulse and directional signals should be transmitted using differential methods with photoelectric blocking. In rational loads (such as electromagnetic relays, solenoid valves), a resistance capacitance absorption or fast discharge circuit is added at both ends. Rational loads can experience a peak voltage of 10-100 times in the initial moment, if the operating frequency is above 20KHZ.

    Target Applications of Kaifull PRMCAS Hybrid Stepper Motors

    Kaifull hybrid stepper motors are mainly used in digital control systems, with high accuracy and reliable operation. If position detection and speed feedback are used, closed-loop control can also be achieved. Stepper motors have been widely used in digital control systems, such as digital to analog conversion devices, CNC machine tools, computer peripherals, automatic recorders, clocks, etc. In addition, they have also been applied in industrial automation production lines, printing equipment, etc.

    The application scenarios of Kaifull stepper motors are very wide, and the following are some application examples:

    Industrial field: Stepper motors are used in automotive instrumentation, machine tool automation production equipment, robot manufacturing, inspection, and process flow.

    Security field: Used for monitoring products, such as PAN/ZOOM/TILT for security cameras.

    Medical field; Hydraulic pumps, ventilators, and blood analyzers used in medical scanners, samplers, digital oral photography.

    In the field of consumer electronics, it is used in various stages of electronic product production, such as solder paste printing, SMT placement, reflow soldering, visual inspection, production of cables with terminals, dispensing machines, screen laminating machines, 3D printers, etc.

    Precision equipment and instruments: used in ATM machines, inkjet printers, engraving machines, photo machines, spray painting equipment, computer peripherals and massive data storage devices, precision instruments, industrial control information systems, office automation, robots and other fields, especially suitable for applications with smooth operation, low noise, fast response, long service life, and high output torque.

    Textile machinery: It is widely used in textile machinery equipment such as computerized embroidery machines. These stepper motors have the characteristics of low torque retention, fast response speed, low operating noise, stable operation, good control performance, and low overall cost.

    Flat mobile devices: such as laser cutting machines, printers, scanners, etc.

    Measurement instruments: such as high-precision 3D scanners, optical measurement equipment, etc.

    Medical equipment: used for medical and surgical instruments, etc.

    Camera lens. Used for focusing and moving optical devices, etc.

    These application scenarios typically require stepper motors to have characteristics such as high precision, low noise, fast response, and long lifespan to meet the positioning, control, and performance requirements of different industries.
