Full-enclosed type three-dimensional direct-driving motor platform device

The invention discloses a full-enclosed type three-dimensional direct-driving motor platform device, belonging to the technical field of motor operation platforms. The device comprises an X-axis direct-driving motor platform, a Y-axis direct-driving motor platform and a theta-axis direct-driving motor platform. With the adoption of the direct-driving motor platform in an X-Y-theta axis linkage manner, a motor at any position within an effective travel can be captured and positioned; the device is fast in speed, large in acceleration, rapid in response, high in positioning precision, free from travel limit, high in efficiency, low in motion noise, long in service life and small in abrasion; a double position limit, i.e. a travel switch and mechanical position limiting, is adopted for a sliding part of the platform, so that the safety performance is high; and the device adopts a full-enclosed type structure, so that the motor and a grating are protected effectively.
