Is there a ring pulse distributor in the step motor drive?
Step motor drive. It's the rotation of the voltage, the rotation of the field, so that the motor can rotate. In general, our access to the motor is a pulse sequence, the pulse sequence needs to pass into the recycle in each motor phase winding, requires the circular distribution, circular distribution, general test drive to complete, that is, to drive you into the pulse sequence, the drive ring automatically assigned to each winding stepping motor
Circular distribution can be divided into soft circular and circular distribution, the so-called soft ring distribution, is through the programming, the method of using software through high-speed triple tube, or light coupling to the motor coil voltage distribution. The hard loop assignment, which I mentioned in 3, USES a hardware driver to complete the loop allocation.
There is a circular pulse distributor in the motor drive, as long as a single chip is given the direction signal and the pulse signal. If the "drive" that is used is not a real drive, it is simply a drive that amplifies the power, That would require a single chip program to do the pulse allocation without the need for additional directional and pulse signals.
should first understand the mechanism and principle of stepper motor, stepper motor of a permanent magnet rotor, in how many different rotor slot, the coil winding of the stator is a phase. 2) the rotation principle, which circulates the various phase wheels into direct current, creates a rotating magnetic field, which is rotated by the rotating field. The faster the magnetic field spins, the faster the motor spins.
