How do you test a VEX motor?
VEX Testing Methods
- A motor is spun at free speed.
- A brake is slowly applied (linearly increasing in torque over time), bringing the motor down to a predetermined RPM.
- The brake is slowly released and the motor is allowed to return to its free speed.
What is motor free speed?
The free speed RPM of a motor is relevant only as a reference measurement based on the amount of power being supplied to the motor. In general terms, the faster a motor runs at free speed the less torque or output power it will produce. These either limit the speed or power being produced.
What is a VEX motor?
A VEX motor module is, very simply, a continuous rotation servo. These servos use internal electronics to identify the current angle of the motor, and using an input signal, are told what position is desired.
What is the maximum programmable speed of a VEX 393 motor?
|Output Stage Driving Gear||Output Speed (RPM)|
|Standard Motor 393 Gearing||10t||100|
|High Speed Option (included with Motor 393 )||14t||160|
|Turbo Gear Set (sold separately)||18t||240|
What does a VEX shaft encoder do?
The Optical Shaft encoder is used to measure both relative position of and rotational distance traveled by a shaft. It works by shining light onto the edge of a disk outfitted with evenly spaced slits around the circumference.
What does a VEX clutch do?
These clutch modules are designed to protect the gears internal to the motor from “shock-loads”. The motor, even in a stall situation, CANNOT exert enough force to break the internal gears.
How is motor RPM calculated?
How to Calculate Motor RPM. To calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 — for the number of seconds in a minute — by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM.
How is motor power calculated?
Power = (Force x Distance) / Time For electric motors, power or horsepower can be calculated from the torque and speed. For example, if you have a motor rated for 3,000 RPM and 6 in-lbf then the horsepower is calculated below.
What is a potentiometer vex?
A potentiometer (or “pot”) is an electrical device used to measure angular position. This varying voltage can be measured by the VEX microcontroller and is directly proportional to the angular position of the shaft connected to the center of the potentiometer.
What is Vex V5?
VEX V5 represents our fifth generation of education robotics systems developed with 20 years of experience using robotics to teach STEM principles. VEX allows students to hone critical computational thinking skills needed to succeed in both the 21st century’s workforce and in everyday life.
What is VEX IQ?
VEX IQ is a programmable, snap-together, robotics system. Watch code come alive on a physical robot and learn key STEM skills that easily transition into the real world.
How big is a VEX motor?
|V5 Smart Motor Specifications||2-Wire Motor 393 + Motor Controller 29|
|Dimensions||2.26” W x 2.82” L x 1.30” H (57.3 mm W x 71.6 mm L x 33.0 mm H)||1.97” W x 2.16” L x 0.98” H (50 mm W x 55 mm L x 25 mm H)|
|Weight||0.342 lbs (155 grams)||0.209 lbs (95 grams)|
What is the problem when there is a yellow LED light Blipping at your robot controller?
A solid yellow light on your Litter- Robot control panel indicates that the unit is cycling or paused, and requires no action from you. However, a flashing yellow light could mean one of two things: Flashing slowly (about once per second) means the Litter- Robot clean cycle was interrupted.
When multiple robots are operating at the same time you should?
When multiple robots are operating at the same time you should: Always be aware of your surroundings. How many joysticks control the robot’s drive train in Tank control?
