Industrial Hollow Shaft Motor Reducer
BCSA (Bonsystems Cycloidal Smart Actuator) is a motor reducer based on a cycloidal gear system. By integrating a cycloidal gear within a frameless motor, it delivers high torque even in an ultra-thin profile. Its hollow structure enhances design flexibility, while the low gear wear ensures exceptional durability.
In today’s industrial landscape, there is a growing demand for products optimized for energy efficiency and heavy-load operations. In particular, the electrification of actuators is being actively pursued as an alternative to traditional hydraulic systems, which suffer from high maintenance costs and low efficiency. Aligned with this trend, BCSA presents a new possibility as an electric actuator, replacing conventional hydraulic solutions across various applications.
