Accuracy Requirements

The precision requirements and precision control requirements for engraving machine according to the customer’s application area. In general, two-phase 85mm stepper motors are commonly used on the market. The engraving machine is a combination of X, Y, and Z axe. The X-axis is to control left and right movement, the Y-axis is to control forward and backward, and the z-axis is to control up and down movement.

Engraving Machines

Engraving is a combination of drilling and milling in terms of processing principles, and the engraving machine has multiple data input modes as needed. There are two types of computer engraving machines: laser engraving and mechanical engraving, both of which have high power and low power. Low power is only suitable for making two-color boards, building models, small signs, three-dimensional crafts, etc., while carving jade, metal, etc., the power needs to be above 1500W. The high-power engraving machine can be used as a small-power engraving machine. It is most suitable for large-scale cutting, embossing, and carving.

Everything You Need To Know About Stepper Motors

What is a stepper motor?

A stepper motor is a type of brushless synchronous DC motor, unlike many other standard types of electric motors, it does not just continuously rotate for a number of spins until the DC voltage passing to it is turned off.

On the contrary, a stepper motor is a precise start and stop of a digital input and output device. They are constructed in such a way that the current passing through it hits a series of coils arranged in phases, which can be powered on and off in quick sequence. This allows the motor to go through a small part of the rotation, these separate predetermined stages, which we call "steps."

Stepper motors are designed to break a complete rotation into many smaller (essentially equal) partial rotations. For practical purposes, these can be used to guide the stepper motor through a set angle or rotation. The end result is that stepper motors can be used to transfer precise movements to mechanical parts that require high precision.

Stepper motors are usually digitally controlled as a key component in an open-loop motion control positioning system. They are most commonly used in holding or positioning applications, where their ability to assert more clearly defined rotational position, speed and torque makes them ideally suited for extremely demanding motion control tasks.

Types of stepper motor

2 phase stepper motor

The 2 phase stepper motor is a hybrid stepper motor with 2 phase. The stepper motor has the following advantages: First, good overload. The speed is not affected by the size of the load. Stepper motors have strict requirements on speed and position. The second is easy to control. The stepper motor rotates in units of "steps", and the digital features are more obvious. Third, the stepping motor has a simple structure. The traditional mechanical speed and position control structure is complicated and difficult to adjust. After adopting the stepping motor, the whole machine has a simple and compact structure.

Hybrid stepping motor

Hybrid stepping motors allow for more precision through techniques such as half-stepping and micro-stepping. Micro-stepping is a method to increase the number of fixed steps within the motor, which sends an alternating sine/cosine waveform to the coil through a programmed drive. Doing so usually means that the stepper motor can be set to run more smoothly and more accurately than the standard setting.

Hybrid stepper motors usually have two poles or teeth, and the magnets around the two different cups are offset outside the rotor. This also means that stepping and rotation can be controlled more precisely, as well as providing quieter operation, higher torque size ratio and greater output speed than standard stepper motors.

Powerful capabilities of highly reliable stepper motors

Stepper motors are often mistakenly regarded as lessers of servo motors, but in fact, they are highly reliable, just like servo motors. The motor runs accurately and synchronously with the pulse signal output from the controller to the driver to achieve highly accurate positioning and speed control. Stepper motor is a high torque stepper motor, and has low vibration at low speeds, ideal applications requiring fast positioning in short distances.

"Stepper motor? Servo motor must have better performance." When asked about stepper motor, this is a typical response. Obviously, there is a major misunderstanding about stepper motors. In fact, stepper motors have been used in various types of applications, such as advanced equipment and convenient automated instruments.

 

What Is a Hybrid Stepper Motor

 We all know that the main function of any motor is to convert electrical energy into mechanical energy, speed, and torque. Therefore, the special feature of stepper motors is that they have the ability to precisely manage the control related to the functional angle and speed. Let’s start with the concept of stepper motors, and then continue to understand hybrid stepper motors. Therefore, stepper motors are also called stepping motors and belong to the category of brushless motors, which divide a complete rotation into equal phases. In this way, the position of the motor can be instructed to rotate and stop on any phase having no use of a position sensor for the feedback.

All motors convert electricity, voltage, and ampere into mechanical power, torque and speed. The unique feature of stepper motors is that they can control the speed and rotation angle very accurately. The stepper motor is a brushless DC motor, therefore, an electronic drive commutating winding is required. To control the rotation, electrical pulses are input to the driver, and the motor rotates one step for each pulse. Since the motor can run in an open-loop without feedback, the good stability of the motor makes the control circuit simple.

Hybrid stepper motor definition

Taking advantage of the combination of variable reluctance and a permanent magnet, a stepper motor is designed. In a similar aspect of permanent magnet motors, hybrid stepper motors also have permanent magnets present in the rotor teeth. This pair of teeth is called a cup-circulating rotor. They are magnetized to produce a pair of magnetic poles, namely the north and south poles. In addition, there are hybrid control-type stepper motors that provide enhanced performance and response. In addition to the open-loop system, it also provides the advantages of a closed-loop system.

Through this kind of motor, the position of the motor can be continuously observed, so that the driver can switch between closed-loop and open-loop lop according to the situation. In general, the function of the motor is to observe and control the application is similar to a normal stepper motor. When there is an error between the position of the motor and the command due to excessive load, the system automatically turns to a closed-loop like a servo motor. This will update to the exact speed level and position, thereby maintaining the desired position.

Hybrid stepper motors are composed of variable reluctance and permanent magnet motors. The rotor of the hybrid stepper motor is axially magnetized like a permanent magnet stepper motor, and the stator is electromagnetically excited like a variable reluctance stepper motor. Both the stator and rotor are multi-toothed.

Hybrid stepper motors have an axially magnetized rotor, which means that one end is magnetized as a north pole and the other end is magnetized as a south pole. A toothed rotor cup is placed at each end of the magnet, and the cup is offset by half the tooth pitch.

Hybrid stepping motors look a lot like ordinary motors. One major difference is the assembly of the rotor and stator.

Advantages

The advantages of hybrid stepper motors are as follows:

Every step that occurs in the motor is the smallest

It provides increased torque

The motor provides high braking torque and has a de-energized winding

It can improve performance even at the lowest speed

Minimum stepping speed

Disadvantages

The disadvantages of hybrid stepper motors are as follows:

The inertia of the motor is large

Due to the presence of rotor magnets, the design, weight, and structure of the motor are more complicated

Changes in magnetic strength will affect the reliability and efficiency of the motor

Compared with variable reluctance motors, hybrid stepper motors are more economical.
