A permanent magnet direct drive motor for parallel robots and its parallel robot structure

Abstract

The invention discloses a permanent magnetic direct drive motor for a parallel robot and a parallel robot structure thereof. The permanent magnetic direct drive motor comprises a rotor, a stator for driving the rotor to be moved, and a brake element for including or separating the rotor and enabling the rotor to be moved or static. The stator is positioned at one end of the rotor, and the brake element is positioned at the other end of the rotor. The middle part of the rotor is vertically provided with an output shaft. The output shaft is positioned in the middle of the stator and the brake element. The parallel robot structure comprises a fixing platform, a driven arm, a knuckle bearing, a medium shaft tube, and a moveable platform. The circumferential part of the fixing platform is fixedly connected with three permanent magnetic direct drive motors. The permanent magnetic direct drive motor for the parallel robot and the parallel robot structure are capable of reducing the volume of the driving device, and reducing the system price. The output shaft of the motor is positioned in the middle of the motor, the space is effectively used, the bearing stress is balanced, and the bearing wear is reduced. The permanent magnetic direct drive motor for the parallel robot and the parallel robot structure have the advantages of the direct drive and high control accuracy and the like.

Description

technical field [0001] The invention relates to a permanent magnet direct drive motor, in particular to a permanent magnet direct drive motor for a parallel robot and the structure of the parallel robot. Background technique [0002] The driving motor used in parallel robots needs the moving axis to drag the active arm to achieve reciprocating motion at a certain angle. The traditional technology uses the cooperation of general motors and reducers to achieve low-speed and high-torque. This solution not only requires many transmission devices, but also the control method Complexity will undoubtedly increase the cost of the robot, and also cause problems such as the size of the robot is too large. However, because the output shaft of the general direct drive motor is located at one end of the motor, when it is applied to a parallel robot, it is easy to cause problems such as unreasonable use of robot space, uneven force on the motor bearing, and serious wear and tear.
