Motor 393#

Introduction#

A Motor 393 is a DC motor controlled through a VEX Motor Controller 29 (MC29). The MC29 connects a Motor 393 to a 3-wire Brain port and controls how much power is sent to the motor.

A Motor 393 can spin forward or reverse and can be stopped. Unlike a Smart Motor, a Motor 393 does not report position, velocity, current, power, torque, efficiency, or temperature.

The VEX Motor Controller 29.

By default, forward spins a Motor 393 counterclockwise, and reverse spins it clockwise. Direction choices can change depending on how the motor is configured in the Devices window.

Below is a list of available Motor 393 blocks:

Actions — Stop and spin a Motor 393.

Settings — Adjust Motor 393 settings.

spin Motor 393#

The spin Motor 393 stack block spins a Motor 393 forward or reverse forever. The Motor 393 will continue to spin until it is given another action, like spinning in a different direction or stopping.

  spin [Motor393A v] [forward v]

Parameters

Description

device

The Motor 393 to spin. Choose from the Motor 393 devices configured in the Devices window.

direction

The direction the Motor 393 spins. By default, the choices are forward and reverse. Direction choices can change depending on the motor’s configuration.

Example

  when started
  [Spin the Motor 393 forward, then stop.]
  spin [Motor393A v] [forward v]
  wait (1) seconds
  stop [Motor393A v]

stop Motor 393#

The stop Motor 393 stack block stops the selected Motor 393 from spinning.

  stop [Motor393A v]

Parameters

Description

device

The Motor 393 to stop. Choose from the Motor 393 devices configured in the Devices window.

Example

  when started
  [Spin the Motor 393 for 1 second, then stop.]
  spin [Motor393A v] [forward v]
  wait (1) seconds
  stop [Motor393A v]

set Motor 393 velocity#

The set Motor 393 velocity stack block tells a Motor 393 how fast to spin. A higher percentage makes the Motor 393 spin faster and a lower percentage makes the Motor 393 spin slower.

Every project begins with each Motor 393 spinning at 50% velocity by default.

Note: A higher velocity makes the Motor 393 spin faster, but it may be less precise. A lower velocity makes the Motor 393 spin slower, but it can be more precise.

  set [Motor393A v] velocity to [50] [% v]

Parameters

Description

device

The Motor 393 to set the velocity of. Choose from the Motor 393 devices configured in the Devices window.

velocity

The speed the Motor 393 will spin at. Percent uses whole numbers from 0% to 100%.

unit

The velocity unit: %.

Example

  when started
  [Spin the Motor 393 at full speed.]
  set [Motor393A v] velocity to [100] [% v]
  spin [Motor393A v] [forward v]
  wait (1) seconds
  stop [Motor393A v]
