The subdivision technology of the stepper motor is essentially an electronic damping technology, and its main purpose is to weaken or eliminate the low-frequency vibration of the stepper motor, and improving the operation accuracy of the motor is only an incidental function of the subdivision technology. For example, for the step angle of ? If the number of subdivisions of the subdivision driver is set to 4, then the running resolution of the motor is each pulse, and whether the accuracy of the motor can reach or approach depends on other factors such as the subdivision current control accuracy of the subdivision driver.

The accuracy of the subdivision drive can vary greatly from manufacturer to manufacturer; The larger the number of subdivisions, the more difficult it is to control the accuracy.

The number of subdivisions of the stepper motor driver.

There are three general methods of segmentation.

to the nth power, as in the subdivision of an integer multiple as in subdivision, as in the subdivision, as in the integer multiple of subdivision.

Then choose different products according to your actual needs, the choice with high requirements is better, and the choice with low requirements is inferior.

The number of subdivisions is adjusted according to the speed and torque you need Generally speaking, the number of subdivisions is to vibrate the stepper motor The motor jitter can be slowed down or reduced to an acceptable degree by subdivision The subdivision can also be adjusted according to the demand for the motor speed In short, the subdivision has a lot of functions for the stepper motor Generally speaking, there are two subdivision algorithms of binary and pentary.

A weight of 10kg and a reel of 50mm (now assuming that the reel you are using is 50mm), you can get the torque of the weight: 10*, because the arm is half of the diameter of the shaft, i.e., where: in.

Usually the selection needs to have more than 50% margin, it is recommended to select a stepper motor or a larger one, such as.

What is the running speed, if the speed is not high, it is recommended to add a deceleration mechanism will be more cost-effective.

Considering the influence of friction, inertia and speed on torque, it is recommended to choose the combination of DMA860H and 86HS85. Please communicate with Si Anji in detail for details.

Let's understand the structure and working principle of stepper motor.

The stepper motor is composed of three elements: step angle (involving the number of phases), static torque, and current. Once the three elements are determined, the model of the stepper motor is determined.

1. The selection of the step angle.

The step angle of the motor depends on the requirements of the load accuracy, the minimum resolution (equivalent) of the load is converted to the motor shaft, and how many angles (including deceleration) should be taken by each equivalent motor. The step angle of the motor should be equal to or less than this angle. The step angle of the stepper motor on the market generally has a degree (five-phase motor).

9 degrees (two, four-phase motors.)5 degrees, 3 degrees (three-phase motors), etc.

2. Selection of static moment.

The dynamic torque of the stepper motor is difficult to determine all of a sudden, and we often determine the static torque of the motor first. The static moment is selected based on the load under which the motor operates, and the load can be divided into two types: inertial load and friction load. A single inertial load and a single frictional load do not exist.

When starting directly (generally at low speed), both kinds of loads should be considered, the inertial load should be considered when accelerating starting, and the friction load should be considered only when running at constant speed. In general, the static moment should be 2-3 times of the friction load, and once the static moment is selected, the base and length of the motor can be determined (geometric size).

3. Selection of current.

The operation characteristics of motors with the same static torque are very different due to different current parameters, and the current of the motor can be judged according to the torque frequency characteristic curve.

How to choose a stepper motor and driver:

Determine how much torque is required: Static torque is one of the main parameters for selecting a stepper motor. When the load is large, a high-torque motor is required. When the torque index is large, the motor shape is also large.

Judge the running speed of the motor: when the speed requirement is high, the motor with large phase current and small inductance should be selected to increase the power input. In addition, a higher supply voltage is used in the selection of drivers.

Select the installation specifications of the motor: such as etc., which is mainly related to the torque requirement.

Determine the requirements for positioning accuracy and vibration: determine whether and how much subdivision is required.

The driver is selected based on the motor's current, subdivision, and supply voltage.

A stepper motor is an actuator that converts electrical impulses into angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate at a fixed angle (called the "step angle") in a set direction, and its rotation is to run step by step at a fixed angle. The angular displacement can be controlled by the co-bending control pulse burn number to achieve the purpose of accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation.

Tung Tree. Stepper motors can be roughly divided into the following types:

Permanent magnet stepper motor: generally two-phase, small torque and volume;

Reactive stepper motor: generally three-phase, which can achieve large torque output;

Hybrid stepper motor: refers to a motor that combines the advantages of permanent magnet and reactive, and it is divided into two-phase and five-phase. This is currently the most widely used stepper motor. Changzhou Sutai Electric Appliances will answer for you, I hope it can help you.

Stepper motor is a kind of induction motor, its working principle is to use electronic circuits, direct current into time-sharing power supply, multi-phase timing control current, use this current to supply power to the stepper motor, stepper motor can work normally, the driver is for stepper motor time-sharing power supply, multi-phase timing controller.

Stepper motors are divided into two-phase stepper motors, three-phase stepper motors, four-phase stepper motors, and five-phase stepper motors.

Stepper motors are divided into 20mm stepper motors, 28mm stepper motors, 35mm stepper motors, 42mm stepper motors, 57mm stepper motors, 60mm stepper motors, 86mm stepper motors, 110mm stepper motors, 130mm stepper motors, and 150mm stepper motors.

For stepper motor selection, it is recommended to consult the manufacturer directly.
