The MG90 mini servo has a compact design and high precision, making it suitable for various applications. Here are the types of MG90 servos:
MG90N Metal Gear Servo
MG90N is a mini servo with metal gears and a plastic case. It is stronger than the MG90 because of the metal gears. The MG90N has a compact design and is suitable for radio-controlled cars, planes, and robots. It works well in tight spaces where regular servos won't fit. The servo has a metal gear, which makes it last longer. It also has a higher torque than the MG90, so it can handle heavier loads. The range of motion is 180 degrees, and it moves quickly, making it ideal for R/C toys and robotics. The MG90N is more accurate and lasts longer under pressure than the MG90. However, it is also more expensive. Overall, the MG90N is a good choice for people who need a strong mini servo.
MG995 Servo
The MG995 is a bigger and stronger servo than the MG90. It has metal gears and a higher torque, so it can handle more weight. The MG995 also turns further, about 180 degrees. It is good for projects that need more power, like radio-controlled cars and robots. But because it is bigger, it might not fit in small spaces like the MG90 can. The MG995 is more accurate and lasts longer under pressure than the MG90. However, it is also more expensive. Overall, the MG995 is a good choice for people who need a strong mini servo.
MG90S Micro Servo
The MG90S micro servo is smaller and lighter than the MG90. It has a plastic case and metal gears, making it more durable. The MG90S has a lower torque than the MG90, but it is still faster. It has a 180-degree range of motion and is used in similar applications as the MG90. The MG90S is more precise and lasts longer under load than the MG90. However, it is also more expensive. Overall, the MG90S is a good choice for people who need a strong micro servo.
There are a lot of things to consider when selecting the right mg90 servo motor for a particular project. Below are some of them.
Torque requirements
Torque requirements are important in choosing a servo motor. The torque rating of the motor should be enough to move the load. If the torque is too low, the servo motor cannot move the load. It will strip the gears. This will cause damage to the motor. It will also reduce its lifespan. A motor with a high torque rating can easily lift heavy loads without straining.
Speed
The response time of the application depends on the speed of the servo motor. A fast servo motor is needed for applications like camera autofocus and robotic arms. The motor must be able to move quickly from one position to another. This will reduce the time taken to complete a task. However, a slow servo motor is enough for applications like models and toys.
Angle of rotation
The angle of rotation of the servo motor affects the designs of mechanical systems. This is because the motor can only rotate within a specific range. The mg90 servo motor can rotate 180 degrees. It can also rotate 270 degrees with a different model. A continuous rotation servo can rotate in full 360 degrees. It is best for systems that require repeated movements.
Control system
The control system of the servo motor determines how complex the wiring and programming are. Some servo motors use PWM signals for controlling the position and speed. They also use analog signals for precise movement. Other servo motors use serial communication like I2C and SPI. I2C and SPI allow multiple servo motors to be controlled at the same time.
Power supply
The power supply affects the performance of the servo motor. The motor needs enough voltage to operate. It should also have a stable current. Some servo motors use batteries as a power source. Others use AC or DC adapters. They also use power supplies with high current ratings.
Position control
The primary role of the MG90 servo is to control the position of an object. It does this by moving its arm within a range of 0 to 180 degrees. The movement is achieved through the application of an electric current to the motor inside the servo. The current activated then causes the motor to turn, which in turn rotates the arm attached to it. This ensures that the desired position of the object is maintained at all times.
Speed control
The MG90 servo also helps in controlling the speed of an object's movement. This is done by adjusting the amount of current supplied to the motor. If more current is given, the motor moves faster, and if less current is supplied, the motor moves slower. This enables a smooth and accurate shift of objects, be it a faster shift or a slower one.
Torque
The MG90 servo also plays a role in ensuring that the object being moved is not displaced from its position. This is known as torque, and the MG90 servo has a relatively high torque that is able to hold objects in place, even if they are moved or if there is outside force.
Metal Gear
The MG90 servo has metal gears that are able to withstand high torque and pressure. This ensures that the servo lasts longer.
Compact Size
The compact size of the MG90 servo makes it easy to fit in small spaces. This is an added advantage when working with projects that have limited space.
Continuous Rotation
The MG90 servo is able to perform continuous rotation. This means it can rotate its arm 360 degrees without any stops in between.
Compact design
The MG90 servo has a small and lightweight design that makes it fit for indoor and outdoor uses with minimal added bulk.
Mounting brackets and horns
Included in the MG90 servo are mounting brackets and horns for easy installation and attachment to the device being used.
Sleek casing
The MG90 servo has a sleek casing that reduces any form of friction and air resistance when in motion.
Overheating protection
Some servo motors have built-in protection against overheating. Overheating can damage the internal components of the servo motor. This can cause it to malfunction or stop working. Overheating protection helps to shut down the motor when it gets too hot. This protects the motor and extends its life.
Short circuit prevention
The MG90S mini servo motor has short circuit prevention. This means that it can detect a short circuit condition and shut down the power immediately. A short circuit can cause serious damage to the servo motor and other connected devices. It can also pose a risk of electrical fire. With short circuit prevention, the servo motor protects itself from these damages.
Proper insulation
The servo motor has proper insulation around its wiring and internal components. This protects against electric shocks. Good insulation also prevents any leakage of electricity which can damage the motor.
High-quality materials
The servo motor is made from high-quality metal and plastic materials. This makes it strong, durable, and able to withstand any work pressure.
Reputable brands
Some well-known brands that sell quality servo motors include Adafruit, Parallax, and SainSmart. These brands are known for their quality, reliability, and excellent customer service.
Certifications
The MG90S mini servo motor has RoHS compliance certification. This shows that it meets the environmental and safety requirements. Other certifications include CE markings, ISO certifications, and REACH compliance.
