Product Description Motor Mount and Wheel Kit Overview: The aluminum Motor Mount and Wheel Kit is a precision-machined mechanical drive system designed for mobile robotic platforms. The brushed motors are worm-gear driven, and the main drive axle (0.5” dia.) is cradled in a ball bearing assembly for smooth-rolling performance. The included 36-position disk Quadrature Encoders resolve to 144 discrete ticks per tire revolution for precision navigation. Ready to build your own custom mid-sized robot? This kit pairs well with the Heavy Duty Caster Wheel Kit (#64080) or the Caster Wheel Kit (#28961). Key Features: Machined 6061 aluminum components for smooth, worry-free performance 60 lb. payload capacity Compatible with most any microcontroller 144 encoder positions per revolution provide approximately 0.14” of linear travel accuracy Conveniently positioned pre-tapped screw holes for easy mounting 6” pneumatic tires are suitable for a variety of terrain – style and tread may vary Smooth-rolling quiet performance Aluminum parts precision-machined in California, USA Application Ideas: Autonomous mobile robotic platform Tele-presence robot drive system Remote-controlled “sentry robot” Motor Mount and Wheel Kit Key Specifications: Compatible with the Caster Wheel Kit (#28961) DC Motor nominal operating voltage = 12.0 VDC Approx 95 RPM’s @ 12.0 VDC Torque approx 85 in. lbs per motor assembly Weight = 2.8 lbs (1.27 kg) per assembly, 5.6 lbs (2.54 kg) per set Voltage requirements: 12 VDC nominal Current requirements: 2.5 – 8.0 amps (depending on terrain and load) Communication: Dual – Quadrature Encoder outputs (four 5.0 volt tolerant inputs required) Operating temperature range: 32 to 120 °F (0 to 49 °C) Motor Mount and Wheel Kit Contents: (1) – Motor, 12 VDC, 96 W, brushed (left) (1) – Motor, 12 VDC, 96 W, brushed (right) (1) – 36-position Quadrature Encoder Set (contains 2 encoder assemblies) (#29321) (2) – Motor Bearing Block 2 Aluminum (2) – Wheel, main rim – 6061 Aluminum (2) – Wheel, rim ring – 6061 Aluminum (2) – Robot Drive Axle 2 (2) – 1/8 x 1″ Roll Pin (12) – Screw, #4-40×1/2″, FH, SS (6) – Screw, M6,1 mm x 50 mm SH, Black (2) – Screw, #1/4-20×5/8″,BH,SS (6) – Spacer 0.50″ x 1″, RND, AL (2) – Tire, 6″ x 1-1/4″ Rubber w/tube – style and tread may vary (2) – 0.5″ ID x 1.125″ OD Ball Bearing (1) – Hex Key, 5 mm (1) – Hex Key, 5/32″ Note: Parts, part styles, motor wire terminal configuration, and quantities are subject to change without notice.
