Abstract
The utility model discloses a linear motor drive mechanism, which comprises a first component and a second component sliding corresponding to the first component. The linear motor drive mechanism is characterized in that a magnetic plate and line rails are arranged on the first component; the second component is supported by the line rails; a coil is arranged on the second component; and the motion of the second component is provided with power by an alternating magnetic field generated by energization of the coil and a fixed magnetic field generated by the magnetic plate. According to the linear motor drive mechanism disclosed by the utility model, a traditional rotary servo motor drive structure is abandoned and direct drive is achieved. As a result of no connection drive of parts such as a drive screw rod and a bearing, the linear motor drive mechanism has the advantages of high drive precision, high speed response, stable operation, low noise, low kinetic energy loss and high efficiency. Compared with the prior art, the linear motor drive mechanism has the beneficial effects that the drive positioning precision, the response speed and the dynamic rigidity of a machine tool are improved; the structure of the machine tool is simplified; the size is smaller; the intensity of assembly labor is reduced; the failure rate is reduced and the maintenance and repair are convenient.
