Industrial 4M101B Direct Drive PSC Blower Motor

The Dayton 4M101B Direct Drive PSC Blower Motor is an industrial blower motor designed for direct-drive operation. This model uses a PSC—Permanent Split Capacitor—design and is identified by the 4M101B designation from Dayton, with a shaft speed of 1075 RPM. In a direct-drive configuration, the blower wheel mounts directly to the motor shaft, eliminating belts and pulleys and reducing drive-train complexity. The PSC construction supports continuous operation with a run capacitor to sustain torque during start and run, a common arrangement for blower and ventilation applications where steady airflow at a mid-range speed is required. This combination of attributes—industrial brand, direct-drive layout, PSC topology, 1075 RPM—defines a specific motor in Dayton’s lineup that can be matched to blower assemblies seeking these exact characteristics. When planning a replacement or upgrade, ensure your system’s mounting and shaft dimensions align with a 4M101B unit and that the requested performance aligns with the 1075 RPM specification.
