From DC Motors (grades 4-8):
convert electrical energy into mechanical energy through
the use of electro-magnetic elds and rotating wire coils.
happens when there is any opposing force (such as friction
or a heavy mass) acting as a load and requiring the motor to output torque to overcome it.
If you keep increasing the load on a motor it will eventually stops spinning or .
From Gear Ratio (grades 2-8):
expresses the relationship between a Driving Gear and a
Driven Gear in a system.
A is the gear connected to the input power source, such as a
motor.
A is the gear connected to the output, such as a wheel or
mechanism in a system.
A simple is a connected set of rotating gears that transmits
power from an input to an output. All gears in between the Driving Gear and the Driven Gear that only
transmit power are known as .
From Drivetrains (grades 4-8):
The robotic subsystem that provides the ability to move is often known as a
.
A is the structure of a mobile robot that holds wheels, motors,
and/or any other hardware used to make up a Drivetrain.
is the friction that resists turning.
The is the distance between Drivetrain wheels.
