DC Geared Motor and Wheel Kit, 3-9V, 77RPM

Description

These quality DC Geared Motor and Wheel Kit assemblies include a high torque 3-9VDC motor, motor mount, wheel coupler and 65mm soft rubber wheel.  These work great when building a robotic wheeled vehicle or balancing robot.

PACKAGE INCLUDES:

• 3-9V Geared DC motor, 77RPM
• Wheel, 65mm, Blue Rim
• Aluminum Motor Mounting Bracket
• Brass Motor to Wheel Coupler
• Attachment Screws & Nuts

KEY FEATURES OF DC GEARED MOTOR AND WHEEL KIT, 3-9V, 77RPM:

• 3-9VDC operating voltage
• 77RPM no load, 65PRM normal load
• 80mA operating current with no load, 300mA normal load
• Stall Torque:  10kg.cm
• Wheel Size:  65mm x 26mm

The geared DC motor will operate on voltages between 3-9VDC.

Speed of rotation will depend on the voltage used and whether a PWM motor controller is used for speed and direction control.  Nominally the motor is rated at 77RPM with no load and about 65RPM with a typical load.  A PWM controller can be used to provide slower speeds.

A black powder coated aluminum motor mounting bracket is provided for mounting the motor to the chassis.

The wheels are 65mm high x 25mm wide.  Tires are a soft rubber.  The plastic rim is a  bright gloss blue.

The wheels are mounted to the motor using the supplied brass coupler.

Our Evaluation Results:

These are very nice assemblies for building higher quality robotic vehicles.  The geared motors generate a high level of torque which make these motors very powerful for their size.

Their moderate nominal operating speed requires less PWM control to achieve slower speed operation while maintaining good torque characteristics.

The motor connections use small solder tabs for connecting the wires.  The orientation of the wires will determine the direction of the motor travel.  Connecting the positive lead to the terminal marked with a red dot will cause the motor to turn CW.
