Product Specification

1. Products Overview

Step motor is a motor that converts the electrical pulse signal into the corresponding angle displacement. For each of the pulse signal, the rotor rotates a certain angle accordingly, and the speed is proportional to the input pulses’ frequency. Therefore, step motor is also called pulse motor.

The biggest difference between step motor compared to other control motors is that it receives digital control signals (pulses) and converts into angle displacement accordingly. Enter a pulse signal to get a specified position increment. Compared with the traditional DC control system, such a so-called incremental position control system, the stepper system complexity and cost are significantly reduced. The angular displacement of the stepping motor is strictly proportional to the number of input pulse, and it is synchronized with the pulse in time. Therefore, by controlling the pulse frequency and pulse quantity, the motor shaft speed, and position can be controlled precisely too.

At the same time, Kaifull has solved many problems of traditional stepper drivers buy the latest patented technologies. There are many middle and high end customers globally, and they highly appreciate our stepper motor and drives very much.

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.
