Abstract

A motor (102), pan-tilt platform (100), camera device, and aircraft. The motor (102) comprises a temperature measurement component (2) provided on the motor (102). The temperature measurement component (2) is configured to be electrically connected to a control module (3). The control module (3) is configured to regulate, according to a real-time temperature measured by the temperature measurement component (2), an input electrical current of the motor (102). By directly adding the temperature measurement component (2) to the motor (102), monitoring the real-time temperature of the motor (102), and controlling the input electrical current of the motor (102) according to the real-time temperature, the present invention controls an output torque of the motor (102) to sufficiently utilize a torque characteristic of the motor (102), and prevents the motor (102) from being heat-damaged.

Description

technical field [0001] The invention relates to the technical field of aircraft power devices, in particular to a control method for a motor, a pan-tilt, a photographing device, an aircraft, the motor, and the pan-tilt. Background technique [0002] As an important power source, motors are widely used. After the motor load is adjusted and balanced, the torque required for the normal operation of the motor will be smaller, and the current of the motor will also be smaller. However, when the load of the motor is unbalanced or the wind resistance encountered by the motor is high, the motor needs to continuously output a large torque to maintain its balance, which will cause the motor coil to continue to heat up. If the heat dissipation environment of the motor coil is not ideal, resulting in A large amount of heat accumulates on the motor coil, which may cause the motor to burn out due to overheating, and eventually cause the gimbal where the motor is located to fail, causing ...

AI Technical Summary

Problems solved by technology

[0004] However, the current model cannot accurately estimate the real temperature of the motor coil. There will be two situations where the motor is overheated and the motor is not started, or the motor coil is protected prematurely under the condition of better heat dissipation, which will affect the cloud. normal use of the station

For example, after the motor starts protection due to high temperature, power on the gimbal immediately, and the inertial measurement unit needs to re-estimate the motor temperature through the above current model, and will not start the motor protection until it meets the conditions for starting the motor protection. It takes a certain amount of time for the inertial measurement unit to estimate the temperature of the motor, but the motor is already under high temperature when the gimbal is powered on again, which will cause the motor to burn out due to overheating
