The gearbox uses helical gears on the first stage for reduced noise and improved efficiency, with spur gears for the remaining stages.\n\nThe 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.\n\nKey Features\n\n\nHelical First Stage – Quieter operation and improved efficiency compared to all-spur designs\n\nIntegrated Encoder – 64 CPR Hall effect quadrature encoder (400 CPR at output shaft)\n\nHigh Speed – 1600 RPM no-load speed at 24V with the 6.25:1 ratio\n\nMetal Gearbox – Durable metal gears for long service life\n\nD-Shaped Output Shaft – 6mm diameter, 16mm long for secure hub attachment\n\n\nSpecifications\n\n\nGear Ratio – 6.25:1\n\nOperating Voltage – 24V DC\n\nNo-Load Speed – 1600 RPM\n\nNo-Load Current – 100mA\n\nStall Torque – 3.5 kg·cm (49 oz·in)\n\nStall Current – 3A\n\nEncoder Resolution – 64 CPR (motor shaft) / 400 CPR (output shaft)\n\nEncoder Supply Voltage – 3.5–20V\n\nOutput Shaft – 6mm diameter × 16mm long, D-shaped\n\nMotor Dimensions – 37mm diameter × 65mm length\n\nMounting Holes – 6 holes in hexagonal pattern, 15.5mm centre spacing\n\n\nIdeal For\n\nRobotics platforms requiring high-speed drive\nClosed-loop motor control projects\nMotorised mechanisms needing precise position feedback\n\n\nPackage Contents\n\n1× 6.3:1 Metal Gearmotor 37Dx65L mm 24V with 64 CPR Encoder (Helical Pinion)\n\n\n\nNote: The recommended upper limit for continuously applied loads is 10 kg·cm. Do not screw mounting fasteners more than 3mm into the mounting holes.\n","vendor":"Pololu","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4420,"title":"Default Title","sku":"PL-4698","price":116.63,"on_sale":false,"in_stock":true,"available_quantity":4,"option1":"Default Title"}]}
