You can vary its speed using the slider and change the direction of rotation by selecting the respective button. To control a servo, select either Servo 1 or Servo 2.Servo Drive Modules & Evaluation Kits enable fast development of brushless smart servo motor solutions. The modules have a complete PCB assembly comprising.A DC servo motor is used as an actuator to drive a load. It is usually a DC motor of low power rating.In this tutorial you will learn various ways to control a Servo Motor using Simulink and Arduino.This tutorial can be helpful for learning mathematical modeling, algorithm development and arduino code for motor generation where servo motor is used.Armature of a DC servo motor is specially designed to have low inertia.In some application DC servo motors are used with magnetic flux produced by field windings.The speed of PMDC motors can be controlled by applying variable armature voltage. These are called armature voltage controlled DC servo motors.Wound field DC motors can be controlled by either controlling the armature voltage or controlling rho field current. Let us now consider modelling of these two types or DC servo motors.The physical model of an armature controlled DC servo motor is given inThe armature winding has a resistance R a and inductance La.The field is produced either by a permanent magnet or the field winding is separately excited and supplied with constant voltage so that the field current If is a constant.When the armature is supplied with a DC voltage of e a volts, the armature rotates and produces a back e.m.f eb.The armature current ia depends on the difference of eb and en. This module allows you to control actuators such as DC motors and servo motors.
Servo Motor Control Bluetooth Can OperateHence in this tutorial we will be toying only with the Operating Mode. The Operating Mode is the one in which we will be able to send and receive data between the PIC Microcontroller and the Bluetooth module. Bluetooth can operate in the following two modes:In Command Mode we will be able to configure the Bluetooth properties like the name of the Bluetooth signal, its password, the operating baud rate etc.
Servo Motor Control Code For MotorThe pin connection table is shown belowCheck our other projects to learn more about Bluetooth module HC-05 with other microcontrollers: Out of the six pins only four will be used in the Operating mode. Hence we need not worry about it. The Device name will be HC-05 (I am using HC-06) and the password will be 0000 or 1234 and most importantly the default baud rate for all Bluetooth modules will be 9600.The module works on 5V supply and the signal pins operate on 3.3V, hence a 3.3V regulator is present in the module itself. Servo Motor Control Serial And BluetoothHere we are sending ‘2’ on pressing stop button, which will be read by the Arduino and it will break the while loop and servo will be stopped. Void setup() If we send the value ‘1’ by pressing Start button then servo will rotate continuously until stop button is pressed. Baud rate for serial and Bluetooth communication has also been set to 9600.
