Embodiment Construction

[0060] The carrier applying the driving device of the present invention can carry loads on it, so as to fix the loads, adjust the posture of the loads at will (for example: change the height, inclination and / or direction of the loads) and make the loads The object remains stable in a certain posture. The carrier can be used as an auxiliary device for photography, photography, monitoring, and sampling, and can be used in space-based (such as rotorcraft or fixed-wing aircraft), water-based (such as submarines or ships), road-based (such as motor vehicles) or space-based ( such as satellites, space stations, or spaceships). The carrying object may be an imaging device such as a camera or a video camera, or may be a sensor or the like. In this embodiment, the carrier is taken as an example of a mirrorless camera, and the carrier is applied to an aircraft to illustrate the beneficial effects of the present invention. The micro-single-camera can be fixed on the bearing part throug...

Abstract

The invention discloses a drive device which comprises a first drive motor, a first drive module electrically connected with the first drive motor and a first potentiometer. The first drive motor comprises a first stator, a first rotor rotating relative to the first stator and a first rotating shaft connected with the first rotor. The first drive module comprises a first driver driving the first drive motor. The first potentiometer is arranged on the first rotating shaft of the first drive motor in a sleeved mode, the first potentiometer is used for measuring the position relation of the first rotor relative to the first stator to generate a first position signal and feeds the first position signal back to the first driver of the first drive module, and the first driver sends out a first drive signal according to the first position signal, wherein the first drive signal is used for driving the first drive motor. The drive device is high in drive precision and short in response time. The invention further provides a carrier with the drive device, and a control method of the carrier.

Description

【Technical field】 [0001] The invention relates to a driving device, in particular to a driving device for driving a motor. 【Background technique】 [0002] A load can be mounted on the driving device to fix the load, adjust the posture of the load at will (for example: change the height and / or direction of the load) and keep the load stable at a certain posture. For example, when the load is a camera or video camera, it can be mounted on the driving device and its control method to achieve stable, smooth and multi-angle shooting; when the load is a microphone, it can be mounted on the drive device and its control method to achieve more accurate Get the user's voice. [0003] The driving device in the related art includes a motor and a driving module for driving the motor. The driving module includes a driver for driving the motor and a controller for sending control instructions to the driver. When working, the driver sends a driving signal to drive the motor according to t...
