R503      *Don’t modify motors (mostly). The integral mechanical and electrical system of any motor must not be modified. Motors, servos, and electric solenoids used on the ROBOT shall not be modified in any way, except as follows:

A.     The mounting brackets and/or output shaft/interface may be modified to facilitate the physical connection of the motor to the ROBOT and actuated part.

B.     The electrical leads may be trimmed to length as necessary and connectors or splices to additional wiring may be added.

C.     The locking pins on the window motors (P/N 262100-3030 and 262100-3040) may be removed.

D.     The connector housings on KOP automotive motors listed in Table 8‑1 may be modified to facilitate lead connections.

E.     Servos may be modified as specified by the manufacturer (e.g. re-programming or modification for continuous rotation).

F.     The wiring harness of the Nidec Dynamo BLDC Motor may be modified as documented by FIRST in Nidec Dynamo BLDC Motor with Controller.

G.     Minimal labeling may be applied to indicate device purpose, connectivity, functional performance, etc.

H.    Any number of #10-32 plug screws may be removed from the Falcon 500 and the Kraken X60.

I.       Insulation may be applied to electrical terminals.

J.     Repairs, provided the original performance and specifications are unchanged.

K.     Maintenance recommended by the manufacturer.

The intent of this rule is to allow teams to modify mounting tabs and the like, not to gain a weight reduction by potentially compromising the structural integrity of any motor.
