The technological growth in the robotics field, including humanoid robots, has been remarkable in recent years, with advancements in motors and actuators, which are key to drive and control technologies.
JMAG offers a wide variety of small motors including BLDC, coreless motors, servo motors, and even linear motors that are ready for evaluation. The high-speed, high-precision electromagnetic field analysis technology developed by JMAG can also accurately capture cogging torque, which is a problem in the smooth movement of robot joints
Furthermore, JMAG’s optimization technology easily identifies the appropriate motor to meet required power within limited space across various motor types. Additionally, by linking with thermal, structural, and control models, it allows for simultaneous evaluation of factors like the temperature, vibration, and noise of drive components, enabling evaluations tailored to the diverse requirements of different robot applications.
