Description:

The MG995 is a high-performance digital metal-geared servo that is ideal for medium to large-sized projects requiring high torque and precision. Its metal gears provide added durability and ensure that the motor won't strip in the event of a jam. This servo can rotate up to 60 degrees and has a weight of 55 grams. Each servo comes complete with three arms, screws, and pre-soldered female wires for ease of use. When integrating the servo into a project, it is recommended to use pins 9 or 10, which are commonly used with the Servo library. It is important to note that incorrect wiring can damage the servo, so be sure to connect it correctly to avoid damage. Overall, the MG995 is an excellent choice for projects that demand high torque, reliability, and precision.

Principle of Work:

The principle of working of a servo motor is based on Pulse Width Modulation (PWM). A servo motor is controlled by sending a series of pulses to the control wire. The duration of the pulse determines the position of the servo's shaft. When the servo receives a pulse, it rotates to the corresponding position and holds its position until it receives a new pulse. The servo has a potentiometer connected to the shaft, which measures the position of the shaft and sends this information back to the control circuit.

The control circuit compares the measured position with the desired position, and if there is a discrepancy, it sends a pulse to the servo to correct the position. This process is repeated continuously, allowing the servo to rotate to the desired position and hold it with high accuracy.

Pinout of the Module:

The pinout of the MG995 servo typically consists of three pins:

1. Ground (GND): The Ground pin is used to connect the servo to the ground of the control circuit.

2. Power (VCC): The Power pin is used to supply power to the servo. The operating voltage of the MG995 servo is 4.8~6.6V.

3. Control (Signal): The Control pin is used to send control signals to the servo. The duration of the pulse sent to this pin determines the position of the servo's shaft.

When connecting the MG995 servo to a control circuit, it is important to ensure that the connections are made correctly. Incorrect wiring can cause damage to the servo or the control circuit, so it is important to double-check the connections before powering on the system. Additionally, it is important to consider the current requirements of the servo when choosing a power supply. The servo can draw significant currents when rotating, so it may be necessary to use a separate power supply to avoid overloading the control circuit. It is also recommended to use a filter capacitor, such as a 100uF electrolytic capacitor, across the power supply to help smooth out any voltage fluctuations and prevent interference with other devices in the system.

Applications: 

• Robotics: Servo motors are often used in robots for precise control of movements, such as arm or gripper control.
• Automation: Servo motors are used in automated systems to control movements and positioning, such as in assembly lines or conveyor systems.
• Model Making: Servo motors are used in model makings, such as in radio-controlled aircraft and boats, for precise control of movements and positioning.
• Medical Equipment: Servo motors are used in medical equipment, such as in X-ray machines, for precise positioning and control.
• Industrial Equipment: Servo motors are used in industrial equipment, such as in packaging machines, for precise control of movements and positioning.

Circuit:

A circuit for Arduino to control the MG995 servo using a 5V 4A power supply and with the servo signal pin connected to pin 9:

Library:

 No need to install the Servo library because it's already included with IDE.

Code:  

#include "Servo.h"
Servo myservo;
void setup() {
 myservo.attach(9); // attach the servo signal pin to pin 9
}
void loop() {
 for(int i = 0; i < 180; i++) { // move the servo from 0 to 180 degrees
 myservo.write(i);
 delay(15);
 }
 for(int i = 180; i > 0; i--) { // move the servo from 180 to 0 degrees
 myservo.write(i);
 delay(15);
 }
}

the servo is connected to pin 9, and the Servo.h library is used to control the servo. The code moves the servo from 0 to 180 degrees and then back to 0 degrees in a loop, with a delay of 15 milliseconds between each step. The myservo.write(i) function is used to set the position of the servo and the myservo.attach(9) function is used to attach the servo to pin 9.

Comparisons:

The MG995 and MG946R are both metal-geared servo motors, but they have some differences in terms of specifications and performance:

1. Stall Torque: The MG995 has a stall torque of 9.4kg/cm (4.8v) and 11kg/cm (6v), while the MG946R has a stall torque of 13kg/cm (4.8v) and 15kg/cm (6v). This means that the MG946R has a higher torque capability, which makes it suitable for heavier loads or applications that require higher torque.

2. Operating Speed: The MG995 has an operating speed of 0.20 sec/60 degrees (4.8v) and 0.16 sec/60 degrees (6.0v), while the MG946R has an operating speed of 0.17 sec/60 degrees (4.8v) and 0.13 sec/60 degree (6.0v). This means that the MG946R is slightly faster than the MG995, which can be important in some applications.

3. Dimensions: The dimensions of the two servos are slightly different, with the MG995 being 40.7× 19.7× 42.9mm and the MG946R being 40.7 x 20.0 x 43.0mm. The difference in dimensions may not be significant in most applications, but it's good to be aware of in case space constraints are a factor.

4. Operating Voltage: Both the MG995 and MG946R have a similar operating voltage range of 4.8~ 6.6v.
