ocus of one of the development .

Stepping Motor Driver technology. Subdivision driver is current in the windings of the motor breakdown , powered by a conventional rectangular wave to step wave power . Division drive changes the drive current amplitude decreases , the rotor reaches equilibrium position when excess energy is reduced , reducing the stepper motor oscillations , eliminating the resonance point , the low-frequency , low- speed stable, torque increases , the noise reduced, while without changing the internal parameters of the stepper motor case , the reduction of step angle , to reduce the error step , i.e. step improves the resolution and accuracy. Typical applications for subdivision driving the Axis CNC transformation . Can only be due to the existing three-axis machine tools , and in the production process requires conical camming surface curved grooves , through process analysis requires Axis machining centers can be achieved. The existing vertical machining center can only achieve X, Y, Z ( three ) axis , configuration, high precision machine tool axis linkage system beyond existing machines several times the price , for the transformation of existing machines through the use of rotary workbench achieve fourth axis , the breakdown of a stepping motor technology to achieve high-precision control , users can meet the accuracy requirements .

In recent years , for different types and number of phases of the stepper motor to take a different breakdown of the current control strategy is a hot topic . If the data indicate that , for the two -phase bipolar hybrid stepper motors, cosine -shaped drive current is more ideal, and for stepping motor response generally use fewer ladder-type harmonic drive current is more desirable.
