DC Gear Motor (45 RPM)

WORKING PRINCIPLE: The 45 RPM 12V DC Geared Motor is a simple DC motor integrated with a gear reduction system that converts electrical energy into controlled rotational mechanical motion. When DC voltage is applied, current flows through the motor windings, generating a magnetic field that causes the rotor to rotate. The attached metal gearbox reduces the motor’s higher internal speed to a steady output of approximately 45 RPM while increasing torque. The sealed gearbox, lubricated with lithium grease, ensures smooth, maintenance-free operation with reduced wear and friction.
MODULE STRUCTURE: The motor consists of a standard DC motor coupled with a robust gearbox containing metal gears for enhanced durability and performance. The gearbox is centrally aligned, with the shaft extending through the center, making it a center shaft DC geared motor. The shaft includes a threaded hole for secure coupling with wheels or mechanical components. The structure is compact, sturdy, and suitable for both light and moderate load applications.
PIN CONFIGURATION: The motor has two electrical terminals: Positive (+) – Connect to the positive terminal of the DC power supply, Negative (−) – Connect to the ground or negative terminal of the power supply. Reversing the polarity will reverse the direction of rotation.
INTERFACE CONNECTION: The motor operates on a 12V DC supply and can function within a range of approximately 4V to 12V. It is commonly interfaced with motor driver modules such as L298N when controlled using microcontrollers like Arduino. The driver enables safe operation and provides control over speed and direction.
OUTPUT FUNCTION: The motor provides an output speed of approximately 45 RPM with moderate torque, around 4.2 kg-cm. This makes it suitable for applications requiring a balance between speed and load-handling capability.
OPERATING VOLTAGE: 4V – 12V DC (Nominal: 12V)
SIGNAL CONDITIONING: Speed control is achieved using PWM (Pulse Width Modulation) through an H-bridge motor driver, while direction control is managed by reversing polarity. This allows flexible and precise control in robotic and automation systems.
