Embodiment Construction

[0009] The invention includes a signal generating module, a signal distribution, and a power amplification module. The pulse signal is generated by a single-chip microcomputer AT89S52 and distributed to each phase of the stepping motor. The power amplification part is completed by a drive circuit. The stepping motor module adopts a 35BY48S03 permanent magnet stepping motor. Use the control interface of the upper computer to realize command input, and use the upper computer to display the running status in real time.

[0010] The system circuit of the single-chip microcomputer includes a clock circuit and a reset circuit. The clock circuit of the present invention adopts an internal oscillation mode, and the reset circuit function is to initialize the on-chip circuit of the single-chip microcomputer, so that the single-chip microcomputer starts to run from a certain state. The reset circuit adopts two basic Form: power-on reset, switch reset; 35BY48S03 stepping motor has four gr...

Abstract

The invention discloses a singlechip and VC++-based step motor control device, relates to a step motor control system, and provides the singlechip and VC++-based step motor control device which operates stably and has small step angle, constant torque and low power consumption. The device comprises a signal generation module, a signal distribution module and a power amplifying module, and has the structural key points that: a pulse signal is generated by a singlechip AT89S52 and distributed to each phase of a step motor; the power amplification part is finished by a driving circuit; the used step motor module is a 35BY48S03 permanent magnet type step motor; command input is realized by using a control interface of an upper computer; and a running state is displayed by the upper computer in real time.

Description

Technical field: [0001] The invention relates to a stepping motor control system, in particular to a stepping motor control device based on a single-chip microcomputer and VC++. Background technique: [0002] A stepper motor is a control element that converts electrical pulse signals into angular displacement or linear displacement. Within the rated power range, the motor speed only depends on the frequency and number of pulses of the pulse signal, and is not affected by load changes, that is, add a pulse signal to the motor, and the motor will rotate through a step angle. The existence of this linear relationship, coupled with the small cumulative error of the stepping motor, makes it easier to use a stepping motor to control in the fields of speed and position. However, stepper motors cannot be used routinely like ordinary DC motors and AC motors. It must be driven by a control system composed of a double-ring pulse signal generator and a power drive circuit before it ca...
