💡 What is a jaw-type flexible coupling used for in motor drive systems and how does it help shaft alignment?

• Helps transmit torque between motor and driven shaft with minimal backlash
• Absorbs small angular and parallel misalignment to extend bearing life
• Aluminum jaw design keeps weight down while providing rigidity
• Suitable for servo and stepper applications requiring precise positioning
