Do you know what means back drivability?
Back drivability in an integrated harmonic drive motor refers to the ability of the motor to be driven or moved in the opposite direction by external forces when it is not powered. In other words, it measures how easily the motor's output shaft can be turned or driven by external loads when the motor itself is not actively providing torque.
In applications like robotics, aerospace or semiconductor, back drivability is a critical factor, this characteristic of harmonic drives can be advantageous. It allows for precise control of position and prevents unintended movement.
Like below requirements from our customer,
In wafer transfer systems, which are critical in semiconductor manufacturing, back drivability of the integrated harmonic drive motor can have significant implications for performance and reliability.
Our integrated harmonic drive motors are chosen for their precision and high torque-to-weight ratio. They are effective in maintaining accurate positioning and stability, which is crucial for wafer transfer where micron-level precision is required.
Based on the specific requirments from customer, we recommend below version for them, and also do back drivability tests.
