The aluminum-housing reversible motor is a high-performance power unit designed for industrial automation and light-to-medium mechanical transmission applications, specifically developed for operations requiring bidirectional rotation and reliable torque output. This model features a rated power of 25W and supports a wide voltage input range of 110V–380V, making it compatible with power standards in different regions and facilitating flexible deployment across global markets. The motor’s lightweight aluminum alloy housing provides excellent heat dissipation and corrosion resistance, while its compact structure allows easy installation in space-constrained equipment.
The motor incorporates an optimized stator-rotor design to ensure smooth and stable output during forward and reverse operation as well as continuous running, reducing mechanical vibration and impact on connected equipment. It delivers consistent torque at low, medium, and light-load operating conditions, making it suitable for conveyor systems, small lifting devices, packaging machinery, and automated production lines. The bidirectional capability enables flexible adjustment of operational direction, enhancing production efficiency and operational flexibility.
In terms of transmission compatibility, the aluminum-housing reversible motor supports gearboxes with a reduction ratio range of 3–180K, allowing flexible adjustment of output speed and torque according to actual load requirements. By properly matching the gear reduction system, the motor can provide reliable torque output in a compact footprint, meeting the demands of light-to-medium industrial equipment for continuous, stable, and efficient power delivery.
