Servo Motors for AGV & Mobile Robots - Compact Power That Keeps Moving
AGV and autonomous mobile robots (AMR) require compact, low-voltage, and highly reliable motion. Tiger Motion's 48V DC servo motors and Servo Integrated Gearmotor deliver strong torque in a small footprint for drive wheels, lifting, and steering - keeping fleets running around the clock.
Why Servo Motors Are Critical for AGV & Mobile Robots
· Core role: Servo motors drive the AGV/AMR drive wheels, lifting mechanisms, steering and hoisting-the foundation of mobile chassis power and positioning.
· Special requirements: Battery power requires low-voltage safety (12–100V DC), compact structure, high efficiency and long endurance, and must withstand frequent start/stop and shock.
· Type selection: 48V DC low-voltage servo is the main choice; lifting/steering commonly use Servo Integrated Gearmotor (Gear Servo Motors) with integrated planetary reduction; collaborative AMR can be equipped with Hollow Frameless Torque Motors.
· Tiger Motion product mapping: With 12–100V DC low-voltage servo as the mainstream safe platform, complemented by Hollow Frameless Torque Motors (embedded in hubs/lightweight structures) and Servo Integrated Gearmotor (Gear Servo Motors) with integrated planetary reduction (lifting/steering), plus a miniaturized frame (40–80mm) and high torque density design, and Integrated Transmission Assemblies for all-in-one differential-drive units, meeting the compact space and long battery-endurance needs of mobile chassis.
· Core challenge: Achieving high torque, long endurance and high reliability on a low-voltage platform within limited chassis space is the core of mobile robot power design.

How to Choose Servo Motors for AGV & Mobile Robots
· 1. Determine the motion axes: driving, lifting, steering, hoisting - each axis has different torque and speed requirements.
· 2. Calculate load and acceleration: consider vehicle weight, payload, slope and start/stop frequency.
· 3. Select the voltage level: 48V DC is the mainstream safe platform; 24V or 100V can be chosen for special needs.
· 4. Determine the reduction ratio: for lifting/high-torque scenarios, choose Servo Integrated Gearmotor (Gear Servo Motors) with integrated planetary reduction.
· 5. Evaluate endurance: prioritize high-efficiency magnetic circuit design to reduce battery loss.
· 6. Match communication: ensure the drive supports common mobile-robot buses such as CANopen / EtherCAT.
