Description
Product Overview
The 230V 4 RPM Synchronous Swing Motor is a precision-engineered electrical component designed to operate at a constant speed synchronized with main power supply frequencies. Operating at 230V / 50Hz with a rated speed of 4 RPM, this motor is widely used in ventilation systems to provide continuous, smooth directional oscillation for air blades and dampers. Built with a sturdy metallic casing, internal copper windings, an integrated gear drive shaft, and pre-wired flying leads, it delivers reliable, low-maintenance performance over an extended service life.
