DC Gear Motor (200 RPM)

WORKING PRINCIPLE: The 200 RPM Geared DC Motor is a simple DC motor integrated with a gear reduction system that converts electrical energy into 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 high internal speed to an output of approximately 200 RPM while increasing torque. The sealed gearbox, lubricated with lithium grease, ensures smooth operation with minimal wear and no maintenance requirements.
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, forming a center shaft configuration. The shaft includes an internal threaded hole for easy coupling with wheels or mechanical components. The structure is compact, sturdy, and suitable for robotic and mechanical assemblies.
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 run within a range of approximately 4V to 12V. It is commonly interfaced with motor driver modules such as L298N when used with microcontrollers like Arduino. The driver provides safe switching, direction control, and speed regulation.
OUTPUT FUNCTION: The motor provides an output speed of approximately 200 RPM with moderate torque of around 1.5 kg-cm, making it suitable for applications requiring higher speed with moderate 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 enables precise and flexible control in robotic and automation systems.
