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.

Several Advantages of Stepper Motors

High precision

The rotation angle of the stepper motor can be finely controlled, and each step corresponds to a determined rotation angle, so the rotation accuracy of the stepper motor is very high. Compared with traditional DC and AC motors, stepper motors can more accurately control position and angle, making them suitable for applications that require high-precision position control.

Wide speed adjustment range

The speed of a stepper motor is determined by the driving current and voltage, so the stepper motor can achieve a wide range of speed adjustment. Meanwhile, according to different loads, the stepper motor can adapt to load changes by changing the driving signal, thereby maintaining a constant speed. Based on the frequency of the input pulse signal, smooth speed regulation can be achieved.

Fast response speed

The response speed of the stepper motor is very fast, and it can complete rotation instructions in milliseconds. This is determined by the special nature of the stepper motor control method. Traditional motors require acceleration and deceleration processes to achieve rotation, while stepper motors can achieve rapid rotation by controlling pulse frequency and time.

High torque

A stepper motor can generate a very large torque and maintain a high torque even at high speeds. This is due to the special driving method of the stepper motor, which can maintain a constant torque output in each stepper cycle. Therefore, stepper motors are suitable for applications that require high torque generation.

Long service life and cost savings

The production cost of stepper motors is relatively low, occupying small space, and easy to install and maintain, so their usage cost is very low. Meanwhile, due to the ability to achieve position and angle control through control signals, complex sensors and control circuits in traditional control methods can be eliminated, resulting in cost savings. At the same time, the stepper motor does not need to adjust the phase through brushes and commutators like ordinary DC motors, reducing friction. In addition, we use unique and high-quality materials, so the Kaifu hybrid stepper motor has a long lifespan and hardly requires special maintenance, further reducing customer costs.

The Applications of Kaifull PRMCAS Hybrid Stepper Motors

The stepper motor is mainly used in the field of CNC machine tool manufacturing. The reason why it is mainly used in this field is that the motor does not require A/D conversion and can directly convert digital pulse signals into angular displacement, which is exactly what CNC machine tool equipment needs and cannot be achieved by many other types of motors. Therefore, the stepper motor can be said to be the most ideal executive component of CNC machines, and it will naturally be widely used in the manufacturing field of CNC machines.

Stepper motors can also be used in many other machinery, such as motors in automatic feeding machines and general-purpose floppy disk drives. In addition, it can also be applied in printers and plotters.

Stepper motors have the characteristics of fast start stop and positioning, and are often used as actuators for position control in the field of digital control. In the fast operation of a stepper motor, it is required that the driving circuit provide the driving current to the stepper motor winding as close as possible to the technical specifications required to generate sufficient torque. The maximum allowable temperature on the surface of the stepper motor. Stepper motors are used in conjunction with drivers, and many drivers support subdivision function, which achieves very small step angles and more precise control. The torque of the stepper motor will decrease as the speed increases. The accuracy of a general stepper motor is 3-5% of the stepper angle and does not accumulate. The stepper motor can operate normally at low speeds, but cannot start above a certain speed, accompanied by a whistling sound.

Widely used in ATM machines, inkjet printers, engraving machines, photo machines, spraying equipment, medical instruments and equipment, computer peripherals and massive storage devices, precision instruments, industrial control systems, office automation, robots and other fields, especially suitable for applications that require smooth operation, low noise, fast response, long service life, and high output torque.
