VEX Motor and Servo Information

The following information on the VEX motor and servo were derived from test conducted on April 28 with the test setup indicated. The hardware components are form the VEX kit. The measurement instrument is a HALAD +/- 150 gram gauge. This data is provided to any team who wishes to use it at there own risk. Hopefully official specifications in more detail will be released soon.

Supply voltage beginning of test (controller off) 8.21 V
Supply voltage controller on but no motor load 8.14 V
VEX controller current (no motor load) 95 mA
Controller and motor with no load 300 mA
Motor speed no load 100 rpm
Controller and motor with (motor stalled) 1.6 A
Stall torque (100 gram @ 24.5 in) 2,450 inch grams

Note torque limiting clutch did not activate in stall condition.
Torque limiting clutch measured manually. 3,185 inch grams.

The similar torque measurements (Qty 50) for the servo were less consistent.

Supply voltage beginning of test (controller off) 7.92 V
Supply voltage controller on but no motor load 7.73 V
VEX controller current (no motor load) 85 mA
Controller and servo with (servo motor stalled) 1.3 A
Stall torque reading ranging from 100 grams to 140 grams at the end of a 22 inch arm.
2,200 inch-grams
to 3,080 inch grams.

I hope this helps other in their design effort.
