Abstract

The invention discloses a direct-current motor single chip microcomputer driving method and a driving system for implementing the method. The driving system comprises a single chip microcomputer, an LED (light-emitting diode) display module, a key setting module, a PWM (Pulse-Width Modulation) signal generating circuit, an output snubber circuit and a speed collecting module. The control method is based on a single chip microcomputer system, changes the size of an average voltage according to the duty cycle of voltages on an armature of a direct-current motor and fundamentals of PMW speed governing and accordingly controls the rotation speed of the motor and achieves smooth speed regulation of the direct-current motor, and controls changes of speed through the single chip microcomputer. The driving system is simple and reasonable in overall circuit design, skillfully combines a single-chip microcomputer technology, enables various control functions and algorithms to be completed by utilizing software technologies, provides more flexibility for the control of the direct-current motor, achieves higher performance, meanwhile, can save manpower resources and reduce system costs so as to effectively improve working efficiency.

Description

technical field

[0001] The invention belongs to the technical field of stepping motor control, and in particular relates to a DC motor single-chip microcomputer driving method and a driving system thereof. Background technique

[0002] Electric vehicles do not use petroleum as direct fuel, so they can serve us better and save us more resources. This is worthy of our research. The electric motor in the electric vehicle is the main drive equipment, it has many kinds, but mainly adopts the DC electric motor.

[0003] At present, in the DC motor drive system, a large number of thyristors (that is, silicon-controlled silicon) devices have been used in the KZ-D drive system to supply power to the motor, replacing the bulky generator-motor F-D system, and with the height of electronic technology The development has promoted the gradual transformation of DC motor speed control from analog to digital, especially the application of single-chip technology, which has brought DC motor s...
