=== Robot Group Parts === This is where the list of parts is maintained. The format is to show the quantity, the a text description, a part number (if available) the donating party, and a current replacement cost of the item. A preliminary listing is here: ||'''Quantity'''||'''Picture'''||'''Part number'''||'''Donated By'''||'''Price'''||'''Description'''|| ||4||http://www.allelectronics.com/images/gold/full/DCM-245.jpg||CAT# DCM-245||Glenn||$15.95||Pittman gearhead (gear reduction drive) DC motors , part numbers GM9232C113-R1. These motors are excellent for uses such as reversible remote control applications such as driving wheel vehicles or controlling critical motion. Full rated DC voltage is 24 vdc. The 1/4"OD flat-shaft rotates at the approximate measured speeds below at the various voltages shown. To reverse direction of travel, reverse polarity. Input to output drive ratio is 65.5:1, no matter input voltage. {{{24 vdc - 108 RPM}}}{{{12 vdc - 56 RPM}}}{{{ 6 vdc - 30 RPM}}}{{{ 3 vdc - 6 RPM}}} The two part numbers -R1 and -R3 (revision 1 and revision 3) appear to be identical, and no visible or performance differences can be detected between the two. The motors have two drilled and tapped holes (1.5 inches on-centers) on the front shoulder for mounting. Weight is slightly under one pound. Length of body is 3-1/8 inch. Add 5/8" for length of shaft.|| ||110||http://www.allelectronics.com/images/gold/full/EC-3945.jpg||CAT# EC-3945||rick||$3.00||390 UF 450 VDC SNAP-IN CAPACITOR Nippon Chemi-Con 04F04L. 450 V. 390 uF. 85 deg.

Power supply filtering capacitor, 85 degrees C.|| ||90||(no image available yet)||(none)||Rick||$0.20||Metal Oxide Varistor (MOV), 35VAC, P/N 9437. {{{Capacitance: 3900 pf}}}{{{Clamping Voltage: 110 V}}}{{{Voltage Rating AC: 35 VAC}}}{{{Voltage Rating DC: 45 VDC}}} A metal oxide varistor, or MOV, is a voltage dependent, nonlinear device that provides excellent transient voltage suppression. When exposed to high transient voltage, the metal oxide varistor clamps voltage to a safe level. A metal oxide varistor absorbs potentially destructive energy and dissipates it as heat, thus protecting vulnerable circuit components and preventing system damage.|| ||18||(no image available yet)||(none)||Rick||$0.20||Metal Oxide Varistor (MOV), 7VAC, P/N 9041. {{{Capacitance: 490 pF}}}{{{Clamping Voltage: 34.5 V}}}{{{Voltage Rating AC: 6.5 VAC}}}{{{Voltage Rating DC: 9 VDC}}} A metal oxide varistor, or MOV, is a voltage dependent, nonlinear device that provides excellent transient voltage suppression. When exposed to high transient voltage, the metal oxide varistor clamps voltage to a safe level. A metal oxide varistor absorbs potentially destructive energy and dissipates it as heat, thus protecting vulnerable circuit components and preventing system damage.|| ||25||(no image available yet)||(none)||Rick||$0.10||(unknown protection device), P/N "H N4 275L20".
