To Your Basket Ordering Information Part Number: R246-GM8 Price: $6.00 Weight: 0.07 lbs This low cost internally geared DC motor is an ideal alternative to continuous rotation servo motors. The high torque rating provides an effective solution for building drivetrains in small robotic applications.

More Details:

The Solarbotics GM8 motor contains a 143:1 gear reduction providing a large amount of torque. Inside the housing, a built in clutch alleviates the possibility of burning out the motor during stall conditions. Built in mounting holes simplifies the attachment of the motor. The output shaft has a 7 mm diameter with two flattened sides providing a stronger connection for rotational loads.

The electrical characteristics for this motor are:

• Operating Voltage: 5V
• Output Torque (at 5V): 0.303367 Nm (43 oz-in)
• Operating Speed (at 5V): 70 RPM
• Idle Power Consumption: 5.0 V / 58 mA
• Stall Current: 670 mA

The physical characteristics for this motor are:

• Weight: 32.03 gm (1.13 oz)
• Dimensions: 55 x 48 x 23 mm (2.17 x 1.89 x 0.906 in)
• Output shaft: 7mm diameter (0.275591 in diameter)
