The problem of synchrodrive for gantry-moving milling machines is researched, and two linear motors as traversing drive mechanism of gantries are applied.
Introduces the working principle and characteristic of static advancer and discusses the electricity interlock of static advancer and motor in the application.
Software subdivision and "virtual frequency conversion" technology were adopted in this solution, which realized multigrade, adaptive subdivided drive in operation of stepping motor.
The method of calculating microstepping currents for variable reluctance stepping motor with equal microstep angle was described when motor torque characteristics were sinusoidal shapes.
Provided with a kind of winding switching device, the motor runs with the two windings working simultaneously while underloaded, and with the multi circle winding...
By observation and analysis of the test data, changing the plate steel endshield of motor into the disc iron one can improve the rigidness of endshield, and reduce the axial vibration of motor.
