Abstract

The invention discloses an alternating-current servo control system with a single driver and multiple motors, belonging to the technical field of medical apparatus and instruments. The alternating-current servo control system mainly comprises a motor control part, a motor driving part, a motor switching part and a motor, wherein the motor control part comprises a user interface circuit, a single-chip microcomputer processing circuit, a motor control output circuit and a storage circuit; and the motor driving part comprises an external interface circuit, an auxiliary processor circuit, a main processor circuit, a storage circuit and a power conversion output circuit. A control instruction of a user end or a former control circuit is received by the motor control part, the control instruction and a motor selection instruction are sent to the motor driving part after identification is carried out, and finally, the motor driving part controls the motor. With the adoption of the alternating-current servo control system disclosed by the invention, a plurality of alternating-current servo motors are driven by an alternating-current servo driver, so that the cost is saved, medical apparatus and instruments can be automatically controlled, and the alternating-current servo control system can be applied to controlling servo systems in other fields.

Description

technical field [0001] The invention relates to an AC servo control system with a single driver and multiple motors, which is applied to the occasion where one AC servo driver controls multiple AC servo motors. Background technique [0002] The development of the servo system has gone through the process from hydraulic to electric. Electrical servo systems are divided into direct current (DC) servo systems and alternating current (AC) servo systems according to the type of motor being driven. In the 1950s, brushless motors and DC motors were commercialized and widely used in computer peripherals and mechanical equipment. The 1970s was the most widely used era of DC servo motors. The development of DC servo drive technology is limited by the defects of the motor itself. DC servo motors have disadvantages such as complex mechanical structure and heavy maintenance workload. The rotor is prone to heat during operation, which affects the accuracy of other mechanical equipment ...
