Problems solved by technology

[0005] The traditional DC motor control system is mainly an analog system composed of analog devices. Although the cost is low and the system is easy to implement, the analog system has the disadvantages of easy aging of devices, parameter drift caused by devices changing with temperature, system reliability decline and system upgrade difficulties, etc. Shortcomings become a bottleneck restricting its development

Embodiment Construction

[0021] The principle of the present invention and the specific connection relationship are described in more detail below in conjunction with the accompanying drawings:

[0022] A high-power DC servo motor drive circuit device, which consists of: DSP interface circuit 1, PWM pulse width modulation circuit 2, motor drive circuit 3 and feedback protection circuit 4.

[0023] The described high-power DC servo motor drive circuit device is characterized in that: the controller adopts a TMS320LF2407 digital signal processor, the drive circuit part selects a power integration module TLP250 chip, and the DSP control circuit generates a pulse after debugging through software design , through the TLP250 power integrated circuit module, the pulse changes and enters the drive circuit. When pins 1 and 4 are at high level and pins 2 and 3 are at low level, the motor is running forward; otherwise, the motor is running reversely; The two event manager modules EVA and EVB in the DSP can gener...

Abstract

The invention relates to a drive circuit apparatus for a high-power direct-current servo motor. The drive circuit apparatus comprises a DSP interface circuit, a PWM circuit, a motor drive circuit and a feedback protection circuit. On the basis of the design, a digital signal processor is used as a core; and according to a modularization and digitalization design idea, a DSP-based hardware control system is developed from the perspective of high performance and practicability and a high-power direct-current motor drive circuit control system is realized, so that a requirement of high-performance servo control of the motor is met. And the system has the wide speed regulation and the excellent dynamic response characteristic.

Description

Technical field [0001] The invention relates to a drive circuit device, which belongs to the field of automatic control, in particular to a drive circuit device capable of driving a high-power DC servo motor. Background technique [0002] With the development of social productive forces, motors, as electromechanical energy conversion devices, have been used in various fields of the national economy and people's daily lives. In some industrial productions, the use of high-power motors is more common, such as the mechanical control system for steam generator maintenance in nuclear power plants. The mechanical arm is a six-degree-of-freedom mechanical arm. Different maintenance tasks require a large load capacity. It is also a DC servo motor with a driving power greater than 100w, and there is no high-power finished device on the market. At present, foreign universities and companies have invested a lot of manpower and financial resources to study it. In the 1980s, a series of...
