Servo Motors for Medical Equipment - Micro-Precision, Ultra-Quiet Motion
Medical imaging and surgical systems demand micron-level precision, low noise, and high cleanliness. Tiger Motion's low-voltage servo motors and Hollow Frameless Torque Motors provide smooth, reliable motion for CT/MRI turntables, surgical arms, and rehabilitation devices.
Why Servo Motors Are Critical for Medical Equipment
· Core role: Servo motors drive medical imaging rotary tables, surgical robotic arms, and rehabilitation and dialysis equipment, directly affecting diagnostic accuracy and treatment safety.
· Special requirements: micron-level positioning, low noise and vibration, high cleanliness and reliability; devices near the human body require safe low voltage.
· Type selection: 48V DC low-voltage servo as the main choice; high-precision rotary tables use Hollow Frameless Torque Motors for zero backlash; compact joints use Hollow Frameless Torque Motors.
· Tiger Motion product mapping: Provides 48V DC safe low-voltage servo and Hollow Frameless Torque Motors (smooth, low-noise, zero-backlash rotary tables), covering imaging rotary tables, surgical robotic arms and rehabilitation equipment, meeting micron-level precision, ultra-quiet operation and near-body safe-voltage requirements.
· Core challenge: Achieving micron-level smooth motion and repeatable force control in a clean, near-body demanding environment.

How to Choose Servo Motors for Medical Equipment
· 1. Determine the application scenario: imaging rotary tables, surgical robotic arms, rehabilitation equipment - accuracy and cleanliness grades differ.
· 2. Select the voltage level: devices near the body or portable equipment give priority to 48V DC safe low voltage.
· 3. Determine the accuracy grade: imaging/surgery use high-resolution encoders and zero-backlash solutions to reduce backlash.
· 4. Evaluate noise and vibration: for operating-room scenarios, choose low-cogging, quiet drive designs.
· 5. Force-control needs: for force-feedback/press-fit scenarios, choose linear motors with closed-loop force control.
· 6. Cleanliness and certification: confirm that materials and processes meet medical cleanliness and reliability requirements.
