Motor Connection

Tips: What differences between large and small winding wiring methods of 2-phase unipolar stepper motor?

As for 2-phase unipolar stepper motor, there are 6 motor leads and outgoing lines. Such motor can be driven with unipolar or bipolar driver. When 4-line bipolar driver is used to drive 6-line bipolar unipolar stepper motor, there is great difference in wiring mode and the results will be different. 2-phase unipolar and bipolar stepper motors can be connected through large or small winding connection.
Large winding connection also indicates the series connection. It is generally applied into the occasions when the motor rotates at low velocity. The resistance with such connection is double times of single-phase resistance and inductance is 4 times of single-phase inductance and the rated current is 0.7 times of single-phase current of motor. At this time, holding torque is about 1.4 times of unipolar drive.
Small winding connection is generally applicable for occasions when the motor rotates at high velocity. The characteristic parameters of resistance, inductance and holding torque of the motor are the same as the characteristic of the unipolar drive motor.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
