Miniature multifunctional motor driving controller

Abstract

The invention provides a miniature multifunctional motor driving controller, which belongs to the motor control system in the technical field of electromechanics. The motor driving controller comprises a singlechip control system, a JTAG connecting pin, a motor driving module, two power modules, a maximum current selector, a dial switch, a photoelectric coupled isolating circuit, a motor control input port, a fast recovery diode, a motor driving output port, a power supply input port, a serial communication commutator, a serial communication connector, a digital IO port driving chip and an analog and digit IO port connector, wherein the parts are connected in sequence. The miniature multifunctional motor driving controller provided by the invention integrates a driver and a controller, can control a one-path two-phase step motor and a two-path DC motor, and can realize serial control and networking control. The motor driving controller has the characteristics of abundant ports, multiple functions, wide application, small volume and low cost.

Description

technical field [0001] The invention relates to a motor drive controller, which belongs to electromechanical products. In particular, it is a miniature multifunctional motor drive controller that can drive both a two-phase stepping motor and a DC motor. Background technique [0002] In some non-complicated and low-power motion control occasions, such as the dimming and focusing system of precision photoelectric tracking equipment, micro DC motors or micro stepping motors are often used as actuators. The system generally does not require complex movements, but requires Small size, high reliability, flexible control. At present, there are mainly two types of commonly used motor drive control systems: 1. The mode of using a dedicated motor driver and an external controller. This scheme is simple to control, but has the disadvantage of large size. In addition, the dedicated motor driver can only drive One type of motor, if there are both stepping motors and DC motors in the sy...

At present, there are mainly two types of commonly used motor drive control systems: 1. The mode of using a dedicated motor driver and an external controller. This scheme is simple to control, but has the disadvantage of large size. In addition, the dedicated motor driver can only drive One type of motor, if there are both stepping motors and DC motors in the system, two sets of different drivers are needed; 2. Adopt a general-purpose highly integrated motor drive control system, which has rich interfaces, small size and high control accuracy High, but in order to achieve complex motion control functions, more dedicated motion control chips, such as DSP, will undoubtedly increase the cost and complexity of the system
