What is a unipolar step?

Unipolar step is a 50 percent efficient type of two -phase step engine. The unipolar step motor has two windings for each phase to flow the electric current in only one direction in each winding. This is against the one -off construction of the bipolar step engine, which requires that the electric current flows in both directions. The unipolar step motor is marked as 50 percent efficiency because it uses twice the amount of wire as a bipolar step engine of a similar size, but suddenly disrupts only half of the winding. Each phase of the unipolar step engine consists of two windings with a common ground, resulting in three wires on a phase. In most cases, the common base in the phases will be paired inside the engine, which will lead to five external guide for the two -phase unipolar stepper.

with controlled winding energy via the controller circuit is not a single -round stepped motor circuit does not require brushes used by direct current (DC) engines and the direction of rotationThe shaft is easy to change. The external circuit of the controller may be timed by the energy cycles of the winding so that the unipolar step engine moves forward or backwards the exact number of steps. Combined with another technology, the unipolar step engine can be used to create domestic robotics, Arduino projects and other projects that require precisely timed, angular movements.

Since the winding of the unipolar step engine is disrupted individually by means of the control of the controller, the individual windings are magnetically charged. This electromagnetic charge attracts the gearbox teeth towards the winding and in the range of additional windings. On this Christmas, the current to the first winding is interrupted by the circuit of the driver and directed to the next winding in the series. Once the current is switched from one winding to the next, the teeth of the toothed wheel monitor the magnetic field and step towards the next winding, where the gears are until the process repeats or reverses.

in the step engine is speed, turntableThe moment and direction of movement controlled by the circuit of the driver, which gives these engines a wide range of abilities. The diced engine works in individual steps, so rather than smooth rotation of the DC engine, it produces more noise and vibration than comparable DC motors. On the other hand, the unipolar step engine requires less maintenance because there are no brushes that could wear and create controlled variable movements that are not possible with the DC engine.
