Price in USD:Details


Product Overview



1. Can be installed at any angle
When SM120 is installed in the equipment, there is no need to find an intermediate position. After installation at any angle, it can be compensated to the specified position through position correction.
Advantages: reduce installation links, reduce error rate, improve the efficiency of mass production and the cost of manual

2. Multi-turn and large angle
SM120BL can achieve plus or minus 7 rotations at the highest angle resolution, and adjust the angle resolution to achieve plus or minus 100+ rotations.
Advantages: Achieve more scene applications, modular design shortens the development cycle.

3. Parameter feedback, multiple protection
SM120BL has the following parameter feedback mechanism. The software can monitor parameter changes in real time. When the equipment is running, it dynamically monitors the data changes. When the internal and external environment changes, such as torque
overrun, locked rotor, temperature overrun, etc., the protection mechanism will start , So as to protect the steering gear itself.
Advantages: closed-loop design, dynamic monitoring, protect itself, and extend life.

4. Open PID motor parameter debugging
SM12OBL uses high-precision brushless motors and opens PID to debug the motor motion effects, such as the motor's rigidity, static error compensation, overshoot and other methods.
Advantages: to achieve a more consistent motor motion effect.

5. Features
