Steering Drive Motor

Electric Steering Drive Motor

Steering drive motor is a modular actuator that integrates both steering and driving functions, specifically designed for mobile robot chassis. It is commonly used in Mobile Robot Bases, Automated Guided Vehicle Chassis, and Agricultural Robot Chassis.

Its core components include a servo motor, reducer, encoder, and steering mechanism, enabling precise angle control and reliable power output. This type of motor supports various motion modes, including differential steering, Ackermann steering, and omnidirectional movement (e.g., using Mecanum wheels).

Advantage

Modular Design: Featuring standardized mechanical interfaces (such as flanges and keyways) and electrical connectors, the system is compatible with mainstream robot chassis architectures, supporting quick replacement and scalability.

Multi-Protocol Compatibility: The communication interface supports PWM analog control, CANopen motion control protocol (compliant with CiA402 standard), and EtherCAT high-speed bus, meeting the requirements of various automation systems.

Environmental Robustness: With an IP54 protection rating and wide temperature range design (-20°C to +60°C), it is suitable for industrial environments with dust, humidity, and large temperature variations—such as logistics warehouses, factory production lines, and outdoor inspection applications.

Safety Mechanisms: Built-in protections include overcurrent protection, overtemperature protection, and mechanical limit switches, preventing damage to the motor or load under abnormal operating conditions.

Torque Requirements: Torque is influenced by factors such as load weight, driving surface, tire material, and vehicle speed. For example, a fully loaded mobile robot chassis requires significantly more torque to initiate turning from a stationary position than when already in motion.

Sensor Types

Relative Position Feedback

Requires an initialization sequence (homing sequence), is cost-effective, and is suitable for simple systems.

Absolute Position Sensing

Uses Hall effect sensors or multi-turn absolute position sensors, does not require initialization, is economical and reliable, and is commonly used in industrial robots.

Safety

In environments where humans coexist, steering wheel systems must meet strict safety standards, such as redundant design and fault detection, to ensure safety.

Braking System

In steering wheel motors, brakes are primarily used for parking braking after stopping to prevent vehicle or equipment movement, ensuring stability and safety. This is typically achieved by applying a torque opposite to the motor's rotation direction, causing the motor to decelerate rapidly and stop rotating.
