360AHS150 3 Phase Hybrid Stepper Motor

1. Products Overview

Stepper motor is an executive agency that converts electrical pulses into angle displacement. You can control the angle by controlling the number of pulse to achieve the purpose of accurate position control. At the same time, you can control the speed and acceleration of the motor by controlling the input pulse frequency to achieve the purpose of the speed control.

Step motor, also called as pulse motor is normally classified by structural as: reactive step motors (VR), permanent magnet step motor (PM), and hybrid step motor (HB). Step motor can also be divided into rotation and straight lines according to the form of movement. According to whether there is an encoder, can be divided as open-loop and closed-loop step motors.

Reactive step motor: there are windings on the stator and rotor consisting of soft magnetic materials. The structure is simple, the cost is low, the step distance is small, and it can reach 1.2 °, but the dynamic performance is poor, the efficiency is low, the heating is large, and the reliability is difficult to guarantee.

Permanent Magnet step motor: The rotor of the permanent magnet step motor is made of permanent magnet material, and the rotor is the same as that of the stator. It is characterized by good dynamic performance and large output torque, but this motor has poor accuracy and large steps (generally 7.5 ° or 15 °).

Hybrid Step motor: Hybrid steaming motor integrates the advantages of reaction and permanent magnets both. It has a multi-phase windings, permanent magnet material on the rotor, and multiple small teeth on the rotor and stator to improve the step accuracy. It is characterized by large output torque, good dynamic performance, and small steps, which can meet automation applications which have high precision requirement.

According to the quantity of phases, there are two-phase, three-phase, and five-phase step motors. The most popular is the two-phase hybrid step motor, accounting for about 97%of the market share. The reason is that the two-phase step motor is more cost-effective, and also has satisfactory performance due to subdivision or micro stepping function of its drive.

The basic step angle of a two-phase step motor is 1.8 °/step. Matched with a half-step drive, the step angle is reduced to 0.9 °. Matched with a micro stepping driver, the step angle can be subdivided up to 256 times (0.007 ° per micro step), which can meet the requirement of most applications.

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.
