Geared DC motors can be defined as an extension of the DC motor which already had its Insight details demystified here. A geared DC Motor has a gear assembly attached to the motor. The speed of the motor is counted in terms of rotations of the shaft per minute and is termed as RPM. The gear assembly helps in increasing the torque and reducing the speed. Using the correct combination of gears in a gear motor, its speed can be reduced to any desirable figure. This concept where gears reduce the speed of the vehicle but increase its torque is known as gear reduction. This Insight will explore all the minor and major details that make the gear head and hence the working of geared DC motor. Voltage Rating: 5V - 12V Material: Cast Iron RPM: 150 Rated Torque: 2.1 Kg-cm 5mm Dia shaft with Gearbox diameter: 34 mm Motor Diameter: 28.5 mm Shaft length: 12mm Weight: 85gm No-load current = 600 mA, Load current = up to 7.5 A(Max) The motor has sturdy construction.
