Reely RE-7842804 motoriduttore 12 V 1:19

Robotics hobbyists and automation tinkerers often need a compact, reliable drive unit that delivers useful torque at a manageable speed. The Reely RE-7842804 gearmotor combines a 12 V DC brushed motor with a 1:19 reduction gearbox, giving you a no-load speed of 315 RPM and a rated torque of 0.49 Nm. Its 6 mm D-cut output shaft fits standard couplings and wheels, while solder tabs allow direct wiring into your project.

Key specifications

• Operating voltage: 12 V DC
• Gear ratio: 1:19
• No-load speed: 315 RPM
• Rated torque: 0.49 Nm
• No-load current: 100 mA
• Stall current: 1.5 A
• Shaft diameter: 6 mm (D-cut)
• Motor body diameter: 37 mm
• Motor body length: 50 mm
• Total length including shaft: 65 mm
• Direction of rotation: reversible
• Connection: solder tabs
• Housing material: metal

Why choose it

The metal housing and reversible rotation make this gearmotor suitable for drive systems that need to change direction under load. The 1:19 ratio balances speed and torque, so it works well for small robot wheels, conveyor rollers, or linear actuators.

Ideal use cases

• Small mobile robots and educational kits
• Automated fixtures and camera sliders
• Motorised valves or dispensers
• Prototyping of mechatronic systems

Good to know

The motor is a brushed DC type, so it is simple to control with a basic H-bridge or relay. The D-cut shaft prevents slipping in press-fit hubs. Solder tabs require direct soldering or a suitable connector.
