Problems solved by technology

[0003] However, the existing mechanisms that use a single motor to complete two-way drive are mostly linear rotary permanent magnet actuators, which are composed of internal and external double stators to drive the permanent magnet array to move in two degrees of freedom in linear and rotational directions. The actuator structure Special, complex control, high cost, difficult to serialize and marketize
Or by adding suspension windings to achieve no bearings, so that the linear direction can move freely, but there is no driving force in the linear direction, the sensor is inconvenient to install, and the system control is very complicated

Abstract

The invention relates to a two-way drive mechanism, the drive mechanism includes a linear motor stator and a push rod; the drive mechanism also includes a base, movable sleeves arranged outside the linear motor stator in turn, and a rotary motor with supporting seats at both ends Rotor and stator of rotating electric machines. The mechanism of the invention does not need an intermediate transmission mechanism, simplifies the system structure, avoids transmission gaps and mechanical elastic deformation, and improves the response speed and control precision of the system.

Description

technical field [0001] The invention relates to a driving mechanism, in particular to a bidirectional driving device. Background technique [0002] In order to realize the compound motion of linear and rotational two degrees of freedom, it often requires the combination of two motors. The two motors are realized by using two independent rotary motors, or one linear motor and one rotary motor. This combination of separate linear and rotary motors, and the rotary motor is embedded in the motor, has the disadvantages of difficult sealing and large space occupation. [0003] However, the existing mechanisms that use a single motor to complete two-way drive are mostly linear rotary permanent magnet actuators, which are composed of internal and external double stators to drive the permanent magnet array to move in two degrees of freedom in linear and rotational directions. The actuator structure Special, complex control, high cost, difficult to serialize and marketize. Or by ad...
