2. Understand the methods and precautions used.

As a precision component, the micro stepper motor has many applications in precision equipment, but it is also necessary to pay attention to some problems of use, such as how to play the maximum role of the stepper motor, high temperature will be generated when the equipment is running, whether the micro stepper motor can meet the performance requirements of high temperature resistance, these must be clearly understood with the manufacturer to ensure that the stepper motor can play an effective role.

A stepper motor is a motor that converts an electrical pulse signal into a corresponding angular displacement or line displacement. 

For each input pulse signal, the rotor rotates an angle or one step forward, and the angular displacement or line displacement of its output is proportional to the number of pulses entered, and the speed is proportional to the pulse frequency. 

Therefore, stepper motors are also called pulse motors.

China's stepper motor in the early seventies of the twentieth century began to start, the mid-seventies to the mid-eighties for the finished product development stage, new varieties and high-performance motors continue to develop, at present, with the development of science and technology, especially the development of permanent magnet materials, semiconductor technology, computer technology, so that stepper motors have been widely used in many fields.

Stepper micro motor parameters and uses

Stepper micro motor, also known as miniature stepper motor, is a widely used reduction transmission equipment, micro stepper motor is mainly composed of matrix, mover and linear guide.

The matrix also acts as a stator, with magnetic poles, stator teeth, coils and control circuits on its surface; The mover is located above the stator and has mover teeth on its lower surface; The guide rail acts as a linear bearing, keeping the mover in place.

Micro stepper motor is usually not used alone, need to be equipped with reduction gearbox, encoder together, this is called micro stepper gearmotor, the main transmission structure stepper motor, reduction gearbox, encoder integrated manufacturing assembly, micro stepper gearmotor is widely used in smart home, robots, electronic products, intelligent cars and other industries.

Answer 4

What is a miniature stepper motor？
Stepper motor is an indispensable accessory on many mechanical equipment, because the equipment used is different, so the type of stepper motor is also different, enterprises in the production of stepper motor before going to the corresponding investigation, and then according to user needs to produce products that meet the requirements, in the stepper motor there is an accessory called micro stepper motor. Let's take a look at what a miniature stepper motor is.

What is a miniature stepper motor?

The selection of micro stepper motor should follow the principle of selecting the motor first and then selecting the stepper motor driver, first clarify the load characteristics, and then find the stepper motor that matches the load characteristics by comparing the static torque and torque-frequency curves of different types of stepper motors.

The holding torque of a miniature stepper motor is similar to what a conventional motor calls "power". Of course, there is an essential difference. The physical structure of the stepper motor, different from the AC and DC motors, the output power of the motor is variable.

Generally, depending on the amount of torque required (that is, the torque of the animal body to be carried), the type of motor is selected. Roughly speaking, the torque is below 0.8N.m, choose 20, 28, 35, 42 (the diameter or square degree of the motor body, unit: mm); If the torque is about 1N.m, it is more appropriate to choose a 57 motor.

The torque is stepped in the case of several N.m or more, and how to choose a miniature stepper motor driver is to choose a stepper motor with specifications such as 86, 110, 130.

Answer 5

What are the characteristics of micro stepper motors?

1. Stepper motor is an open-loop control element stepper motor that converts the electrical pulse signal into angular displacement or line displacement.

2. It is an induction motor, and its working principle is to use the circuit to turn direct current into time-sharing power supply.

3. Control the angular displacement by controlling the number of pulses, so as to achieve the accurate purpose; At the same time, the speed and acceleration of motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation.

4. There are three main types of stepper motors in structure: reactive, permanent magnet and hybrid

Reactive formula:

The stator has windings and the rotor is composed of soft magnetic materials.

Simple structure, low cost, small step angle, up to 1.2°, but poor dynamic performance, low efficiency, large heating, reliability is difficult to guarantee.

Permanent magnet type:

The rotor of the permanent magnet stepper motor is made of permanent magnet material, and the number of poles of the rotor is the same as the number of poles of the stator.

It is characterized by good dynamic performance and large output torque, but this motor has poor accuracy and large step moment angle (generally 7.5° or 15°).

Hybrid:

The hybrid stepper motor combines the advantages of reactive and permanent magnet type, with multi-phase winding on the stator, permanent magnet material on the rotor, and multiple small teeth on the rotor and stator to improve the step moment accuracy.

It is characterized by large output torque, good dynamic performance and small step angle, but complex structure and relatively high cost.
