Product description
A robot joint motor is a critical component that powers the movement of a robotic arm or similar systems. It’s typically a rotary actuator, and its key requirements depend on the application, such as precision, torque, speed, and reliability.
Since your rotary actuator already integrates a motor, gearbox, and encoder for high precision, it’s well-suited for robotic joint applications.
Robotic joints, which are sometimes known as axes, are the moveable parts of a robot that cause relative motion between adjacent links. These links refer to the rigid components that connect the joints to ensure their proper and straightforward operation.
The compact size includes servo drivers, motor side absolute value encoder, output side absolute value encoder, and frameless torque motors, brakes, precision harmonic reducers and other main components, which save customers hundreds of mechanical and electronic components selection, design, procurement, assembly labor and time costs.
Features
√ Friction brake mechanism, accurate and reliable brake position
√ Large hollow low voltage driver
√ High precision rotary encoder
√ Combines a torque motor, driver, encoder and high precision harmonic reducer.
