    1. Product Overview

    Step motor is a motor that converts the electrical pulse signal into the corresponding angle displacement or the line displacement. It can use the quantity and frequency of the pulse to control the rotation (rotation angle, rotation speed) in automation applications. For each of the pulse, the motor rotor rotates a angle or forward, and its output angle shift or line displacement is proportional to the input pulse, and the speed is proportional to the pulse frequency. Therefore, step motor is also called pulse motor.

    In the case of non-overload, the speed of the motor and the stop position depends only on the frequency and number of the pulsed input, without being affected by the load change. That is to say, add a pulse signal to the motor, and the motor turns a step distance. The advantage of this linear relationship between pulse and angle rotation, plus that a step motor only has periodic errors without cumulative errors, make step motor widely used in automation speed, position and other control fields easily.

    With the development of product research and development of technology, the performance of the step system has been even more improved. If the stepper system is not overloaded, there will be no step loss mostly nowadays, and life time very long, almost no need maintenance, which makes steppers popular and widely used in many kinds of industrial automation motion control applications.


    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.

    The 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:
