    1. Products Overview

    Step motor is an executive agency that converts electrical pulses into corner displacement. You can control the angle displacement by controlling the number of pulses to achieve the purpose of accurate positioning. At the same time, you can control the speed and acceleration of the motor rotation by controlling the pulse frequency to achieve the purpose of the speed regulation.

    The hybrid step motor is currently the most widely used step motor, and everyone is familiar with the stepper motor. Here, we briefly introduce how to choose the right step motor for our applications.


    How to choose the right step motor for our applications?

    The choice of stepping motor torque

    The torque of the stepping motor is similar to the "power" of traditional motors. Of course, there is an essential difference. The physical structure of the stepping motor is completely different from AC and DC motors and the output power can be variable.

    Generally, we select the motor size according to the torque need in operation. For example, if the torque needed is less than 0.8N.M, frame size 20/28/35/39/42mm stepper motors are suitable. If the required torque is about 1N.M, select 57mm motor. When the required torque is several N.M or even more, usually selected stepping motors with frame size 86/110/130mm or bigger.

    The stepping motor speed selection

    Special consideration should be taken for the speed of the target stepper motor. Because the output torque of the motor is inversely proportional to the speed. That is to say, when the stepper motor speed is low (500-600 rpm or lower speed per minute), its output torque is larger. When the motor speed is increasing, the motor toque will be decreasing and especially when with the speed of 1000rpm and above.

    Sometimes when high-speed motors are needed, the coil resistance, inductance and other indicators of the stepped motor must be considered carefully. Choose a motor with a slightly less inductance is better, as the output torque is normally higher. However, if want low speed and big torque, a stepper motor with inductance no less than 10mH is better.

    Selection of no-load-starting frequency

    This is a more important indicator for buying motors. If it is required to start and stop frequently within a short time, and the speed is about 1000 rpm (or higher), it is usually necessary to "accelerated startup", i.e need a motor with high no-load-starting frequency.

    Phase selection

    Regarding to the choice of the number of step motor phases, many customers do not pay enough attention. In fact, the performance of stepper motors with different phases are different. The more phases, the smaller the steps can be done, and the vibration at work is smaller. In most occasions, two-phase motors are enough. However, if higher performances needed, especially for precision or smoothness, 3-phase or 5-phase can be better.

    Select the protection level

    There are special step motors, such as water-proof and oil-proof, dust-proof for some special occasions. For example, underwater robots, or fountain etc. need waterproof motors.

    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.
