So Motors, i am confused, What is the difference between 11W and 5.5W motors? and then there are discontinued motors. So my team only has 11W motors, should we buy 5.5W? and what is the benefit to having 5.5W motors?
Vex has an 88-watt motor limit for v5. It used to be 8 motors, but since 5.5W motors were introduced, they changed it. This means that if you wanted, you could have sixteen motors, (if they were 5.5W.)
R12: Motors are limited. Robots may use any combination of VEX V5 Smart Motors (11W) (276-
4840) and EXP Smart Motors (5.5W) (276-4842), within the following criteria:
a. The combined power of all motors (11W & 5.5W) must not exceed 88W.
b. V5 Smart Motors, and EXP Smart Motors connected to Smart Ports, are the only motors that
may be used with a V5 Robot Brain. The 3-wire ports may not be used to control motors of
any kind.
Examples of legal motor combinations:
11 watt motors have more power than 5.5 watt motors (watts is a measure of power). You get to adjust speed or torque through your gear ratios (or gear cartridges).
These are the old “393” motors used with the Cortex…there’s even older motors and servos out there. For those who have been around for a while, the “new” 5.5 watt motors are the old 393 motors in a new package.
It depends on what you want to build. The advantage is you can get two motors instead of one if you have an application which doesn’t need the power of an 11 watt motor. Sometimes the motor quantity rules limit creative designs. With the availability of the 5.5 watt motors, small clever mechanisms which don’t need lots of power can be built without taking away your ability to have a good drivetrain.
