DC motor RS-3657CS series

brushed100 V...240 V

RS-3657CS Product Overview
RS-3657CS is a 36 mm class brushed DC motor with a 57 mm body length. It is a high-voltage DC (HVDC) series designed for direct-rectified 100V–240V DC supply and common in professional hairdryers, domestic sewing machines, handheld blenders and similar appliances. Typical performance reaches up to 18,200 rpm and up to 34 W depending on variant.

Customization and Sourcing Notes
KWC Motor offers OEM/ODM customization for winding (voltage), speed, torque, shaft design, cables/connectors, gearbox integration and EMC/noise targets. Shaft diameter is 3.175 mm and motor body length is 57.0 mm for this series. Winding parameters can be adapted to local mains (110V/220V/230V). Quotation requires confirmed application, specification, quantity and customization details.

Core Applications & Solutions

• Professional Hair Dryers & Heat Tools: Models such as RS-3657CS-10180 reach up to 18,200 rpm and ~30 W; extended body length improves rotational smoothness and reduces handle vibration.
• Sewing Machines & Kitchen Appliances: HVDC variants provide strong starting torque and, with the 57 mm rotor, handle heavier loads like thick fabrics or high-viscosity blending.

RS-3657CS-06450 | 220V – 240V | 220V | 5,830 rpm | 4,985 rpm | 8.6 W | 1,156 g·cm
RS-3657CS-10180 | 100V – 230V | 230V | 18,200 rpm | 15,640 rpm | 18.43 W | 1,335 g·cm

Notes
This is a DC motor family requiring a rectifier bridge to convert AC mains to DC for direct drive. High-voltage variants typically use carbon brushes with expected service life around 200–500 hours depending on load and duty cycle. Check thermal conditions and duty cycle for intended application.
