BO Motor Dual Shaft 150 RPM DC Gear Motor – High-Torque Yellow Plastic Gearbox Motor for Arduino Prototyping & Smart Robotics
The BO Motor Dual Shaft (Yellow DC Gear Motor) is a highly popular, low-cost 150 RPM miniature drivetrain actuator engineered for educational robotics and smart car chassis. Operating efficiently across a 3V to 6V DC input range, it leverages an internal 1:48 plastic spur gearbox to output a stable 1.0 kg-cm torque rating while keeping weight under 30 grams. Equipped with twin flattened-oval output shafts, it allows developers to mount a driving wheel and a speed tracking encoder disc simultaneously, making it the premier choice for Arduino and Raspberry Pi mobile rovers.

Description
BO Motor Dual Shaft – High-Torque 150 RPM Yellow DC Gear Motor for Smart Autonomous Mobile Robots
The BO Motor Dual Shaft (Battery Operated plastic gear motor) is the most widely used, cost-effective, and highly reliable drivetrain actuator deployed across India for smart car chassis kits, autonomous line-following rovers, obstacle avoidance drones, and student engineering models. Engineered to balance torque and velocity perfectly, this BO Motor Dual Shaft features an internal multi-stage plastic spur reduction gearbox nested inside a durable yellow housing. This internal gear alignment drops raw high-speed DC motor rotations down to a highly practical 150 RPM, delivering the mechanical torque needed to roll over common field obstructions smoothly.
This premium listing highlights the dual-shaft layout variant available at VirtualPathshala. Featuring extended physical driving axles protruding out of both sides of the yellow gear casing, the BO Motor Dual Shaft gives developers immense construction flexibility. You can mount a high-traction rubber wheel to the primary outer shaft while attaching a digital slotted encoder disc to the internal secondary shaft to track real-time wheel velocity. Complete your mobile robotic drivetrain by combining this gear motor link with our collection of Smart Car Chassis Boards and high-current L298N Dual H-Bridge Motor Driver Modules.
Why Choose a Dual-Shaft BO Motor Layout Over Single-Axle Gears?
Standard single-shaft gear motors limit your design boundaries heavily because they force you to choose between mounting a driving wheel or tracking speed variables. The BO Motor Dual Shaft eliminates this bottleneck completely. It allows you to build a true closed-loop feedback control system. By piping real-time physical rotation ticks from the inner axle back into your microcontroller interrupt pins, your software can instantly modulate motor power via pulse-width modulation (PWM) to maintain a perfectly straight path on uneven floors.
Key Features of the BO Motor Dual Shaft
1. Versatile Twin-Axle Rotational Drive Profile
The core advantage of deploying this specific BO Motor Dual Shaft model is its extended twin-axle layout. The plastic drive shafts match standard 5.5mm flattened-oval wheels natively, allowing for quick, press-fit wheel attachments while completely eliminating gear slippage risks under load conditions.
2. Optimized 1:48 Internal Spur Gear Reduction Ratio
The internal gearbox structure of the BO Motor Dual Shaft houses a train of high-strength plastic spur gears working across a fixed 1:48 reduction layout. This mechanical reduction turns high-speed, low-torque electrical rotations into stable, high-torque physical power, allowing your mobile rovers to scale carpeted inclines easily.
3. Flexible 3V to 6V DC Low-Voltage Operating Envelope
Powering your mobile robotic fleet requires no complex, heavy high-voltage battery arrangements. The BO Motor Dual Shaft operates efficiently across a wide low-voltage range, drawing minimal stall current while delivering peak performance right off common hobby power packs:
- ✅ 2× AA Alkaline Battery Trays – Safe, entry-level 3.0V DC operation for lightweight school kits
- ✅ Single 18650 Lithium Cell (3.7V) – The perfect balance of weight, speed, and cell efficiency
- ✅ 4× AA Rechargeable Batteries or 5V Power Bank Rails – Maximum speed performance tracking metrics
4. Lightweight, Shock-Absorbing Engineering Plastic Shell
The outer gearbox shell and internal gear teeth are molded entirely from high-impact ABS and POM plastics. This specialized material choice keeps the dry weight of each BO Motor Dual Shaft assembly under 30 grams, shielding the inner drive core from structural fractures when smart cars bump into walls during navigation tests.
5. Seamless Hardware Motor Driver Compatibility
Because the internal brushed DC motor draws minimal active current during typical runs, the BO Motor Dual Shaft integrates smoothly with standard hobby motor control architectures without risk of overloading chip paths:
- ✅ L298N Dual H-Bridge Driver Modules – Supports independent direction control for two motor pairs concurrently
- ✅ L293D Arduino Motor Driver Shields – Direct plug-and-play fit for multi-motor 4WD car chassis designs
- ✅ Miniature HG7881 / L9110S Dual Channel Drivers – Perfect for tight, space-constrained mobile robots

Frequently Asked Questions – BO Motor Dual Shaft
How do I mount standard wheels or encoder wheels onto this dual-shaft casing?
The plastic axles on the **BO Motor Dual Shaft** feature flat dual-sided margins. Standard yellow hobby wheels slip straight onto either side with a snug friction-fit. If you plan to implement closed-loop path correction routines, simply slide a standard 20-slot plastic encoder disc onto the back inner axle inside the car frame, positioning it squarely between your infrared optocoupler sensor gate wings.
Should I solder external capacitors across the motor terminal tabs?
While the motor runs fine out of the box, brushed DC motors inherently generate minor electromagnetic sparks on their internal carbon brushes as they spin. This can create high-frequency electronic noise on your shared power rails. To clean up your data signals, solder a tiny 0.1µF (104) ceramic capacitor right across the motor’s positive and negative copper eyelet tabs to filter out voltage noise from your microchips.
Why does my robotic vehicle stutter or stall when trying to turn around?
This is almost always caused by an inadequate current supply line. The **BO Motor Dual Shaft** requires low voltage, but its active current draw spikes toward 800mA per motor when starting up or shifting direction under load. If you are powering multiple gear motors directly from a standard 9V alkaline battery, the battery will suffer a major voltage drop and fail to supply enough current. Use high-discharge rechargeable lithium-ion cells instead to ensure smooth, continuous torque.
