【正文】 ion or cutoff signal. Control circuit output signal power is low, can not provide the necessary stepping motor output power, the need for power amplifier, which is stepper motor driven power drive part. Power stepper motor drive circuit to control the input current winding to form a space for rotating magic field excitation, the rotordriven movement. Protection circuit in the event of short circuit, overload, overheating, such as failure to stop the rapid drive and motor. Motor is usually for the permanent mag rotor, when the current flows through the stator windings, the stator windings produce a magic field vector. The magic field will lead to a rotor angle of rotation, making a pair of rotor and stator magic field direction of the magnetic field direction. When the stator rotating magic field vector from a different angle. Also as the rotor magic field to a point of view. An electrical pulse for each input, the motor rotation angle step. Its output and input of the angular displacement is proportional to the pulses, with pulse frequency proportional to speed. Power to change the order of winding, the electrical will be reversed. We can, therefore, control the pulse number, frequency and electrical power windings of each phase to control the order of rotation of stepper motor. Stepper motor types: Permanent mag (PM). Magic generally twophase stepper, torque and are smaller and generally stepping angle of degrees or 15 degrees。 also have fivephase reaction. Noise, no torque has been set at a large number of out. Hybrid (HB), mon twophase hybrid, fivephase hybrid, threephase hybrid, fourphase hybrid, twophase can be mon with the fourphase dri
