DC motors, including both brushed and brushless types, find wide applications in linear actuators used across industries like robotics, automation, aerospace, and more. Linear actuators convert rotational motion into linear motion, enabling precise movements in a variety of systems, including drones, landing gear systems<\/a>, recreational vehicles, and industrial automation. Hence, choosing the right type of motor, brushed or brushless, is essential to ensure the efficiency, reliability, and lifespan of linear actuators.<\/p>\n

Brushed DC Motor in Linear Actuators: Overview and Working<\/strong><\/h2>\n

A brushed DC motor is a simple, small motor used in linear actuators<\/a>. It utilizes mechanical brushes to commutate the motor, enabling rotational motion, which is then converted to linear motion by the actuator. A brushed DC motor comprises four key components \u2013 stator, rotor, commutator, and brushes.<\/p>\n

Once DC voltage is applied across the brushes, current begins to flow through the rotor windings, creating a magnetic field around the rotor. The stator also has its magnetic field which interacts with that of the rotor, prompting it to spin. The commutator also rotates, changing the current flow direction. This process is called commutation, which ensures continuous changes in the magnetic field and maintains rotational motion by alternating the rotor and stator magnets. In a linear actuator, the motor\u2019s rotational movement is then converted into linear motion via a lead screw or similar mechanism, driving the actuator’s mechanical parts to produce the desired movement.<\/p>\n

Brushless DC Motor (BLDC) in Linear Actuators: Overview and Working <\/strong><\/h2>\n

A brushless DC motor (BLDC) is an advanced motor used in linear actuators for precise, efficient motion. The motor consists of a rotor, stator, and electronic speed controller (ESC). In a linear actuator, the ESC sequentially energizes the stator windings, creating a rotating magnetic field. Its interaction with the rotor\u2019s permanent magnets causes it to spin, converting rotational motion into linear movement via a lead screw or ball screw. The ESC ensures smooth, controlled operation, minimizing power loss and heat generation for efficient actuator performance.<\/p>\n
