Small and speedy wins the race

Modern intralogistics technologies place high demands on drive systems. In many instances, drives must release tremendous force in confined spaces and perform precise positioning tasks in continuous or stop-and-go operations. Speed is also essential, as many thousands of orders must be processed daily.

To speed up warehouses, automatic storage and retrieval machines, driverless transport systems, and intelligent logistics robots are taking over an increasing number of work steps in storing, retrieving, and preparing items for dispatch. Flexible systems that work reliably around the clock keep operations moving cost-e ectively and are often driven by high-performance micromotors. Small motors are crucial for controlling robot movements, enabling them to navigate environments, manipulate objects, and perform various tasks. Examples of how motors are used in warehouse robots include:

• Wheel propulsion: Mobile robots employ motors to drive their wheels or tracks. By controlling the speed and direction of the wheel motors, the robot can move forward, backward, turn, or navigate in di erent directions.

• Steering: Motors are used for steering mechanisms in robots with multidirectional capabilities. By controlling the rotation of the steering motors, the robot can change its direction of motion or perform complex maneuvers.

• Actuation: Motors can act as actuators to perform various tasks. For example, they can be used in robotic arms for grasping, lifting, or manipulating objects. They can also extend or retract appendages, open and close doors, or operate other mechanical components.

• Sensors and feedback control: Encoders or other position sensors can be attached to the motors to provide feedback on their speed, position, or torque. The control system uses this feedback to adjust and regulate the motor’s behavior, ensuring accurate and precise movement.

• Balance and stabilization: By controlling the torque and movement of the motors, robots can maintain balance and stability while navigating uneven terrain.

• Obstacle avoidance: Motors can be combined with sensors to prevent collisions. The sensors detect obstacles or proximity to objects, and the motors are controlled to steer the robot away from potential hazards.
