Electric motors of the unipolar type are frequently utilized in applications requiring precise placement and control.
Because it uses a center-tapped common wire as a point of reference and only has one winding per phase, it is known as a "unipolar" inductor.
Multiple electromagnets are arranged in a circular arrangement around a rotor to create a unipolar stepper motor.
Sequentially energizing each electromagnet produces a magnetic field that interacts with the rotor and moves it in distinct steps.
A unipolar stepper motor's windings can be either unipolar or bipolar in type.
In a bipolar configuration, the motor has two distinct windings per phase and currently passes through each winding in both directions.
A center-tapped winding is used in a unipolar configuration, in contrast, where the current only flows in one direction through each side of the winding.
In order to create a spinning magnetic field, the windings of a unipolar stepper motor must be activated in a particular order.
Utilizing a stepper motor driver, which regulates the current flow to the motor windings, is the traditional method for achieving this sequence.
The motor may move forward or backward by precisely controlling how the electromagnets are powered, giving it control over its position.
Unipolar stepper motors have several benefits and drawbacks when compared to bipolar stepper motors.
They have the benefit of requiring simpler driving circuits because of their center-tapped winding design. Switches and transistors make it simple to control the direction of the current.
However, because they utilize only half of the winding at a time, unipolar stepper motors are frequently less effective than bipolar stepper motors.
Only half of the winding is actively contributing to the motor's torque production due to the center-tapped common wire's role as a current return path.
Unipolar stepper motors are nevertheless commonly utilized in numerous applications that value simplicity and ease of control despite their inferior efficiency.
They are frequently used in automated systems such as printers, CNC machines, robotics, 3D printers, and others that call for accurate placement and control of mechanical parts.
The Global Unipolar Stepper Motor Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Oriental Motor is happy to announce the official launching of the EH3-AZAKH, a new unipolar stepper motor product that has been added to our line of electric grippers.
The brand-new EH3-AZAKH (short for EH3) is an electric gripper with an AlphaStep AZ Series attachment. It is smaller and weighs 200g, which is about 55% less than the EH4 gripper.
Its dimensions are 80.5mm x 36mm x 42.5mm. A delicate, human-like grip can be achieved by adjusting the gripping force starting at 2N (reference value).
The EH Series has a sturdy rack & pinion design that is reliable and enables the integration of a straightforward pick-and-place or measurement device onto the end of an arm or a system.
The new AlphaStep AZ Series-equipped EH3 electric gripper's standout characteristics are: Lightweight and compact design, smallest grip, lengthy stroke, Robotic mounting flange: This flange may be fitted to industrial robots that are already on the market, which saves time in the design and manufacture of jigs.
Installation flanges on the robot side comply with JIS B 8436 and ISO9409-1.
