Lead Wiring Type

Description

This precision-mechanism AC reversible motor is designed based on the 4RK specification, emphasizing both structural stability and smooth operation, enabling reliable start-stop control in various drive applications. The entire unit utilizes a 25W power configuration, allowing for stable torque output within a compact size, suitable for mechanical environments requiring continuous operation or frequent forward and reverse rotation. The motor supports a multi-voltage input range of 110V to 380V, ensuring stable operation across different regions and equipment standards, facilitating flexible integration into complex systems.

Its core feature lies in its wide range of gear reduction ratios from 3 to 200K, allowing selection of the required output speed and torque level based on actual operating conditions, meeting the needs of mechanical structures such as precision positioning, slow propulsion, and synchronous operation. The internal structure has been specifically optimized to ensure smooth operation during forward and reverse switching, reducing impact on the mechanical transmission system and helping to extend the service life of related components. The motor's design prioritizes a compact layout and robust housing structure, making it more suitable for equipment with limited installation space or vibration restrictions. Its overall performance is more suitable for use in experimental equipment, precision machining devices, automated actuators, small transmission systems and other scenarios, and can help users obtain stable and controllable mechanical motion output.
