Description

The smooth braking AC motor is a drive product designed for industrial applications requiring high comfort during start-stop processes and system stability. Its focus is on reducing impact and vibration during braking, ensuring controlled and smooth motion during equipment stoppage. This model utilizes a 5RK motor structure with systematic optimization of mechanical strength and electromagnetic parameters. With a rated power of 120W, it provides continuous and stable power output under high load conditions, laying the foundation for smooth operation in complex working environments.
This smooth braking AC motor supports a wide voltage input range of 110V–380V, allowing for flexible application in different power supply environments and industrial systems, reducing the difficulty of electrical adaptation when deploying equipment in different projects and regions. The built-in braking unit emphasizes the continuity of the braking engagement and release process. By optimizing the braking response curve, it effectively mitigates mechanical shock caused by sudden changes in instantaneous braking force, ensuring good operational consistency during deceleration and stopping.
This motor is suitable for automated production lines, conveying equipment, assembly stations, and industrial machinery requiring high operational smoothness. Its design philosophy is to achieve low-impact, predictable braking performance at higher power levels, providing equipment manufacturers and system integrators with an AC motor solution that balances power output and operational quality.
