DC motor RS-4266DT series

brushed12 V36 V

RS-4266DT Product Overview
RS-4266DT is a 42 mm class brushed DC motor with an extended 66 mm body length. The longer can increases rotor length and magnetic working area compared with the RS-4260 platform, enabling higher continuous torque and greater power density. Typical marketed support covers 12–36 V with deep OEM/ODM customization available.

Customization and Sourcing Notes
KWC Motor offers OEM/ODM options for winding, voltage range, speed/torque profiles, shaft design (including D‑cut and knurled), pre-soldered leads or connectors, gearbox integration, and EMC/EMI suppression. Price and lead time depend on application details, specifications, quantity and customization requirements.

Target Applications & Solutions
With a 66 mm can, RS-4266DT provides higher torque reserve than shorter 42 mm variants. It suits applications requiring low-speed high-torque output or higher power density in limited diameter envelopes, such as smart-home actuators and handheld or bench power tools.

Heavy-Duty Blinds & Curtains
Suitable for large motorized blinds, roller shutters and window actuators where low-speed, high-torque operation is needed. Use with an appropriate gearbox to increase lifting capacity and stabilize low-speed performance.

Power Tools & Automation Equipment
Applicable to handheld drills, electric screwdrivers and conveyor or automation drives. Selected variants deliver up to ~85 W and stall torque values suitable for intensive duty cycles; confirm thermal and duty-cycle limits per model.
