The built-in motor serves as the core component determining overall performance of linear actuators. Its type, technical parameters and adaptability to working conditions directly govern the actuator’s thrust stability, service life, operating precision and user experience.

Maintenance Tips The main body of BLDC motors barely suffers wear. Around 90% of malfunctions stem from electronic control systems. No mechanical maintenance is required; only regular inspection of wiring and controller status is needed

Linear actuators do not extend or retract directly driven by motors. Linear motion is realized via a three-stage transmission assembly: motor + reduction gearbox + screw-nut pair. Any performance defect of the motor will be amplified stage by stage and degrade overall unit performance.

Currently, motors matched with linear actuators in the industry mainly fall into two categories: brushed DC motors and brushless DC motors (BLDC). A small number of high-power industrial actuators adopt AC motors. These motors differ greatly in structure, performance, cost and applicable scenarios, serving as the core standard to grade actuator products.

Motor parameters fundamentally determine the thrust, speed and stability of linear actuators. Different from general-purpose motors, actuator motor parameters are defined combined with linear transmission characteristics. The key core parameters are listed below:
