## Description

A powerful 24V brushed DC gearmotor with a 6.25:1 metal gearbox and integrated 64 CPR quadrature encoder. The gearbox uses helical gears on the first stage for reduced noise and improved efficiency, with spur gears for the remaining stages. The integrated Hall effect encoder provides 400 counts per revolution of the gearbox output shaft, enabling precise speed and position control. The 37D series form factor features a 6mm D-shaped output shaft and standardised mounting holes. Key Features Helical First Stage – Quieter operation and improved efficiency compared to all-spur designs Integrated Encoder – 64 CPR Hall effect quadrature encoder (400 CPR at output shaft) High Speed – 1600 RPM no-load speed at 24V with the 6.25:1 ratio Metal Gearbox – Durable metal gears for long service life D-Shaped Output Shaft – 6mm diameter, 16mm long for secure hub attachment Specifications Gear Ratio – 6.25:1 Operating Voltage – 24V DC No-Load Speed – 1600 RPM No-Load Current – 100mA Stall Torque – 3.5 kg·cm (49 oz·in) Stall Current – 3A Encoder Resolution – 64 CPR (motor shaft) / 400 CPR (output shaft) Encoder Supply Voltage – 3.5–20V Output Shaft – 6mm diameter × 16mm long, D-shaped Motor Dimensions – 37mm diameter × 65mm length Mounting Holes – 6 holes in hexagonal pattern, 15.5mm centre spacing Ideal For Robotics platforms requiring high-speed drive Closed-loop motor control projects Motorised mechanisms needing precise position feedback Package Contents 1× 6.3:1 Metal Gearmotor 37Dx65L mm 24V with 64 CPR Encoder (Helical Pinion) Note: The recommended upper limit for continuously applied loads is 10 kg·cm. Do not screw mounting fasteners more than 3mm into the mounting holes.
