393号发动机

介绍

Motor 393 是一款直流电机，由 VEX 电机控制器 29 (MC29) 控制。MC29 将来自 3 线 Brain 端口的脉冲宽度调制 (PWM) 信号转换为驱动 Motor 393 的可变电压。

This page uses motor_393 as the example Motor 393 name. Replace it with your own configured name as needed.

以下是可用方法列表：

• spin – Spins a Motor 393 forward or reverse until stopped.

• set_velocity – Tells a Motor 393 how fast to spin.

• stop – Stops a Motor 393 immediately.

• set_reversed – Sets a Motor 393 to have its direction be reversed.

• Motor29 – Creates a Motor Controller 29.

旋转

spin rotates a connected Motor 393 in a specified direction using the current motor velocity.

Usage:
motor_393.spin(direction, velocity, units)

参数	描述
direction	The direction in which to spin the Motor 393: 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

设置速度

set_velocity 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.

Usage:
motor_393.set_velocity(value, units)

范围	描述
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

停止

stop stops the connected Motor 393 immediately.

Usage:
motor_393.stop()

参数	描述
	此方法没有参数。

设置反转

set_reversed sets the Motor 393 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 Motor29.

Usage:
motor_393.set_reversed(value)

参数	描述
value	Whether the Motor 393’s direction is reversed: True — Reverses the Motor 393’s direction. False — Returns the Motor 393’s direction to its default.

构造函数

Constructors are used to manually create Motor29 objects, which are necessary for configuring a Motor Controller 29/Motor 393 outside of VEXcode.

Motor29

Motor29 creates a Motor Controller 29.

Usage:
Motor29(port, reverse)

范围	描述
port	The 3-Wire Port that the motor is connected to: On the EXP Brain – Ports.PORTx 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 393’s spin should be reversed. True – FORWARD will spin clockwise False (default) – FORWARD will spin counterclockwise

# Create a Motor Controller 29 in Port A
motor_393 = Motor29(brain.three_wire_port.a)
