Features and Working Of Geared DC Motor
An extension of the DC motor, as the name suggests, geared DC motor has a gear assembly attached to the motor. The speed of this DC motor is calculated in terms of rotations of the state made every minute. A popular term for this is RPM, which stands for rotation per minute. The gear positioning of the DC gear motors are designed to enhance the torque and reduce the speed considerably. Based on a precise combination of gears in the gear motors, speed can be reduced to a desirable figure. In machinery where gears are present to decrease the speed and increasing torque is called as gear reduction. Here we will discuss features and function of a DC gear motors.
External Structure dc motor gear
Looking at a geared DC motor, you will think it to a straight extension of the regular or simple DC motor. Along with a regular DC motor, there is a gear head with rotatory shaft. In another view of the DC gear motor, you will see the exterior protrudes of the gear head. A nut is carefully placed at the shaft, which is used to mount the motor to other parts of the assembly. In addition, an internal threaded hollow space is evident that allows attachments and extensions, for instance a wheel, to the motor.
Working dc motor gear
Regular DC gear motors mechanize over a fair range of Voltage. Higher the input, higher will be the RPM outage of the motor. Let’s say, for example, the motor operates in the range of 6-12 Volts, then it will have minimum rotation per minute at 6 V and maximum RPM at 12 V. The working can be explained with the help of the principle of conservation of angular momentum. The gear with smaller radius will have higher RPM, in comparison to the one with a broader or larger radius. Additionally, larger radius means higher torque to smaller radius and vice versa.
A variety of specifically designed geared DC motors is available at the best manufacturers in China. Experience and advanced technology must be deciding factors to find the right manufacturing company.
