Victor Motor

Introduction

The VEX Victor Motor Controller is a legacy motor controller that takes a 3-Wire PWM signal from the Brain to control VEXpro/EDR DC motors that can’t plug directly into Smart Ports.

This page uses victor_motor as the example Victor Motor Controller name. Replace it with your own configured name as needed.

Below is a list of available methods:

• spin – Spins a motor forward or reverse until stopped.

• stop – Stops a motor immediately.

• set_velocity – Tells a motor how fast to spin.

• set_reversed – Sets a motor to have its direction be reversed.

Constructor – Manually initialize a Victor Motor Controller.

• MotorVictor – Creates a Victor Motor Controller.

spin

spin rotates a connected motor in a specified direction using the current motor velocity.

Usage:
victor_motor.spin(direction, velocity, units)

Parameters	Description
direction	The direction in which to spin the motor: FORWARD – By default, this is counterclockwise REVERSE – By default, this is clockwise
velocity	Optional. The velocity to spin with from 0% to 100% when using PERCENT. This can be an integer or decimal (float). If the velocity is not specified or previously set, the default velocity is 50%.
units	Optional. The velocity unit: PERCENT RPM (default) – Rotations per minute VelocityUnits.DPS – Degrees per second

stop

stop stops the connected motor immediately.

Usage:
victor_motor.stop()

Parameters	Description
	This method has no parameters.

set_velocity

set_velocity tells a motor how fast to spin. A higher percentage makes the motor spin faster and a lower percentage makes the motor spin slower.

Every project begins with each connected motor spinning at 50% velocity by default.

Usage:
victor_motor.set_velocity(value, units)

Parameter	Description
velocity	The velocity to spin with from 0% to 100% when using PERCENT. This can be an integer or decimal (float).
units	Optional. The velocity unit: PERCENT RPM (default) – Rotations per minute VelocityUnits.DPS – Degrees per second

set_reversed

set_reversed sets the motor to be reversed so that the FORWARD direction will spin clockwise. This method works the same as setting the reverse parameter to True when constructing a MotorVictor.

Usage:
victor_motor.set_reversed(value)

Parameters	Description
value	Whether the motor’s direction is reversed: True — Reverses the motor’s direction. False — Returns the motor’s direction to its default.

Constructors

Constructors are used to create MotorVictor objects, which are necessary for configuring a Victor Motor Controller.

MotorVictor

MotorVictor creates a Victor Motor Controller.

Usage:
MotorVictor(port, reverse)

Parameter	Description
port	The 3-Wire Port that the Controller is connected to: On the EXP Brain – brain.three_wire_port.x where x is the number of the port. On a 3-Wire Expander – expander.a where expander is the name of the expander instance.
reverse	Optional. Sets whether the motor’s spin should be reversed. True – FORWARD will spin clockwise False (default) – FORWARD will spin counterclockwise

# Create a Victor Motor Controller in Port A
victor_motor = MotorVictor(brain.three_wire_port.a)
