[Installation process]
1 Download the sofa butler to install the file to the U disk → 2 settings allow "install unknown applications" → 3 find the installation package through the HD player → 4 complete the installation
ã€Steps】
1. Baidu search for "sofa manager" into the sofa network, download the sofa butler package; or directly click the link (http://app.shafa.com/shafa.apk) to download the sofa butler package.
Copy the downloaded apk installation package to the U disk.
2. Open "TV Setup" → "Account Security" and set "Install unknown source applications" and "Mileon Security" to "Allow".
6, open U disk, find the sofa butler package.
7. Install the sofa butler and open it.
If the installation fails, restart the device and try again by following the steps (may be useful).
The development of direct-drive servo motors for steering wheels was mainly targeted at precision agricultural machinery. It can complete agricultural machinery operations, achieve precise positioning, improve agricultural productivity, effectively use agricultural resources, and protect the ecological environment. This is an effective way to achieve high-quality, high-yield, low-consumption, and sustainable environmentally-friendly agriculture. It can achieve fast, efficient, high-precision and automated operations on large areas of arable land. It is mainly used in multiple production links of land production, pesticide sowing, harvesting and spraying, which greatly improves production efficiency and land use.
Motor design characteristics:
adopts direct drive motor design
Waterproof and dustproof design
Integrated design of motor and servo control
Easy and fast installation
The rotor is directly coupled to the load shaft
Control performance characteristics:
AC Servo Solution Design
SVPWM vector control, fast system dynamic response
Dedicated encoder, high control accuracy and good stability
With speed control mode and position control mode
Extremely high running accuracy:
This machine adopts sine wave, vector control and high-precision magnetic encoder, with high control precision, which can ensure that the vehicle can walk within the error range of ± 2cm.
Good control line performance:
The torque of the direct drive servo motor increases in proportion to the input current and does not change with speed and angular position. The relationship between torque and current is linear. Multi-pole structure design, low motor torque ripple coefficient, stable operation, can effectively reduce the "S" curve amplitude when the vehicle is going straight
Powerful acceleration and deceleration capabilities:
The direct drive design of the servo motor enables gearless transmission. The ratio of torque to inertia on the load shaft is much better than gear transmission, which greatly improves the acceleration capability of the system, and greatly improves the ability to go online quickly in applications and the ability to correct errors under high-speed vehicle operation
Not easily deformed
The direct drive motor is mounted directly on the load shaft. No gear gap, no elastic deformation, high transmission efficiency, good rigidity, etc., suitable for steering wheel control characteristics. While ensuring high torque, it is also convenient for human emergency operation
Faster response time
The mechanical constant and electrical time constant of the direct drive servo motor are small, which ensures fast response in applications under a wide range of operating speeds, greatly improving the sensitivity of the system and improving the straight line of operation.
