1. Pay attention to cleanliness Ensuring the cleanliness is very necessary to ensure cleanliness in use. 2. Pay attention to lubrication Different seasons and operating temperatures have different requirements for lubricating oil. Pay attention to meeting the viscosity of lubricating oil to reduce equipment wear. 3. Pay attention to maintenance Attention should be paid to maintenance, maintenance requirements, and replacement of worn parts to ensure their effectiveness in use and to meet functional stability.

It may be that the subdivision is small or large, and the foot will be large with a small step. When the working voltage of your data signal is too low or too high, it is also possible that the photocoupler in the drive will not digest well. Too short a time between the start and end rate to the maximum rate or the interaction rate between the maximum rate and stillness can also cause tremors.

When choosing a motor, please be careful not to work in the vibration zone from the beginning. With high vibration and noise, the failure rate will also increase. If the vibrator must work, it is recommended to change the voltage, current or add damping to solve it.

The angular displacement output by the motor is proportional to the number of input pulses, and the speed is proportional to the pulse frequency. Change the sequence of energizing the windings and the motor will reverse. Therefore, the number of pulses, frequency, and the energization sequence of each phase winding of the motor can be used to control the rotation of the stepper motor. By controlling the number of pulses and pulse frequency, the angular displacement of the motor and the speed of the motor are controlled to achieve open-loop control. In addition, there is always a corresponding error between the angle of each step of the stepper motor and the theoretical step distance. From a certain step to any step, there will always be a corresponding error. However, the number of steps per revolution of the stepper motor Similarly, under the condition of not losing a step, the step error will not accumulate for a long time.

1. Voltage The power supply voltage of the hybrid stepping voltage driver is generally a wide range, and the power supply voltage is usually selected according to the working speed and response requirements of the motor. If the motor has a high working speed or a fast response requirement, then the voltage value is also high, but note that the ripple of the power supply voltage cannot exceed the maximum input voltage of the drive, otherwise the drive may be damaged. 2. Current The current of the power supply is generally determined according to the output phase current I of the driver. If a linear power supply is used, the power supply current can generally be 1.1-1.3 times I; if a switching power supply is used, the power supply current can generally be 1.5-2.0 times I.

Hybrid stepping motors are divided into two-phase, three-phase and five-phase: the two-phase stepping angle is generally degrees and the five-phase stepping angle is generally degrees. As the number of phases increases, the stepping angle decreases. It is small, the accuracy is improved, and the application is very wide.

In a high-power brushless DC motor, the optocoupler circuit and the control circuit can be integrated separately. The optocoupler circuit outputs the rated power, the synchronous motor of the drive motor is wound, and can be controlled in the control loop. The optocoupler circuit has changed from a large linear shape to a pulse width modulated power switch, and the relative power circuit composition has also changed from a discrete circuit of a transistor to a modular design integrated circuit chip.

The stepper motor converts the differential signal into angular velocity or linear offset. It is a special motor for operation. The tachometer motor converts the speed into a voltage and transmits it to the input terminal as a feedback signal. The tachometer motor is an auxiliary motor, installed at the end of the ordinary DC motor, and the voltage generated by the tachometer motor is fed back to the DC power supply to achieve the purpose of controlling the speed.

The stepping motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. The input of the control pulse of the stepper motor does not depend on the position of the rotor, but rather sends out its control pulse according to a fixed law. The stepper motor only relies on this series of established pulses to work. This control method is due to the uniqueness of the stepper motor. It is more suitable for controlling stepper motors.

1. The user's improper operation method. 2. Excessive development of applications. When the hybrid stepping motor is used in low-speed gears, the speed ratio per minute should not exceed 1000 rpm, preferably between 1000-3000PPS. It can be used in this way according to the speed reduction equipment. At this time, the motor has a high working efficiency, Low noise.

The stator motor rotor of the stepper motor is a very important component, but the stator motor rotor will rust, so which rust inhibitor can prevent rust? The stator motor rotor of the stepping motor adopts water-soluble resin soft film anti-rust agent, or water-replaceable storage anti-rust agent, which can prevent rust. The water-replaceable storage anti-rust agent penetrates well and has low viscosity, which is more suitable for the surface structure of the motor rotor. In addition, the water-replaceable storage rust inhibitor can also avoid the corrosion of fingerprints and hand sweat.

Stepper motors have a variety of design specifications, such as 20mm, 28mm, 35mm, 42mm, 57mm, these. In fact, on the whole, stepper motors with the above diameters can be counted as small and medium-sized stepper motors. Relatively speaking, the 20mm stepper motor is a small and medium-sized stepper motor, followed by a 28mm stepper motor and a 35mm stepper motor.

Changing the rotation position of the stepper motor can not only change the position pulse signal data signal of the automatic control system, but also adjust the wiring of the motor to change the direction. The specific method is as follows: For two-phase motors, only need to interchange the motor wires in one of the phases and connect the stepper motor controller. It is necessary to pay attention to changing the rotation position of a stepper motor. For a three-phase motor, the motor wires in one phase cannot be exchanged, but the two phases in it should be exchanged in order.

If the specific transmission ratio is slow in the basic theoretical speed ratio, it may be caused by out-of-step and excessive load; if the theoretical speed ratio is also slow, it means that the single-pulse frequency is low. Increasing the single-pulse frequency can increase the speed ratio.
