Brushless motor RB-4817-CE

BLDC12 V24 V

Product overview
RB-4817-CE is a 48 mm flat outer-rotor brushless DC motor (BLDC) designed for compact equipment requiring high torque density in limited axial space. The motor body thickness is approximately 18 mm. Typical uses include ATMs, vending machines, office printers, shredders, projectors, fans and compact automated modules.

Key facts for engineering buyers

• Product category: Outer-rotor brushless DC motor (flat)
• Model: RB-4817-CE / RB-4817
• Manufacturer: KWC Motor
• Primary benefits: high torque density in a low-profile package, suitable for space-constrained drive modules
• Typical customization: shaft, lead wire, connector, mounting, winding and electrical parameters

Specifications

• Outer diameter: 48 mm class
• Body thickness: approx. 18 mm
• Voltage options: customizable (commonly configured between 12 V and 24 V)
• Stall torque: up to 11 kg·cm (depends on winding and operating conditions)

Customization and sourcing notes
KWC Motor supports OEM/ODM customization for voltage, winding, shaft design, lead wires, connectors, mounting interfaces, speed/torque targets and EMC/noise requirements. Quotation and lead time are confirmed after specification, quantity and customization scope are agreed. Use datasheet drawings to confirm mounting dimensions and shaft details before sampling.

Target applications and design fit

• ATMs & vending machines: flat outer-rotor layout reduces axial height while providing usable torque for intermittent dispensing and transport mechanisms
• Printers, shredders & office automation: suitable for paper-feed, cutting and compact drive modules where space and torque balance is required
• Fans & projectors: compact motor package for blowers and optical assemblies

Engineering selection notes

• Confirm supply voltage and winding configuration for the target speed/torque point
• Verify duty cycle and thermal environment to ensure permissible continuous operation
• Confirm shaft length, mounting interface and lead wire routing with drawings
• Specify noise and EMC targets if critical for the application

Comparison with typical cylindrical motors

• Installation space: flat 18 mm body reduces axial height compared with many cylindrical inner-rotor designs
• Torque density: outer-rotor construction enables higher torque for a given diameter
• Integration: easier height integration but verify axial clearance and bearing/support requirements

Purchasing FAQ
