Product Description

The 150 RPM Centre Shaft motor is built around a high-quality DC motor coupled with a circular metal gearbox. The 6mm D-shaped shaft ensures that wheels, pulleys, or gears attached to it do not slip under high load. Because the gears are made of hardened metal, they can withstand the mechanical stress of sudden starts, stops, and reversals common in autonomous robotic competitions.

Key Features

  • All-Metal Gear Train: Unlike plastic gears that strip under load, these metal spur gears ensure a long operational life and consistent torque delivery.

  • Easy Mounting: The face of the gearbox features threaded holes, making it compatible with standard L-shaped motor brackets.

  • Wide Voltage Range: While optimized for 12V, the motor can run at 6V (approx. 75 RPM) for precision tasks or up to 15V for short bursts of speed.

  • Quiet Operation: Precision-cut gears minimize mechanical noise, allowing for smoother and quieter robot movement.

  • D-Type Output Shaft: The flat section on the 6mm shaft provides a secure mechanical "lock" for set screws, preventing the wheel from spinning freely on the shaft.


Technical Details

  • Motor Diameter: ~37mm.

  • Shaft Length: ~15mm to 20mm.

  • Total Weight: ~150 grams.


Prototyping and Engineering Tips from Robogears

  • Motor Driver Selection: Since this motor can draw over 1 Amp when stalled, use a driver like the L298N Dual H-Bridge Module or an IBT-2 43A Driver for heavy-duty applications. Small drivers like the L293D may overheat if the robot encounters an obstacle.

  • Power Supply Tip: Always use a Li-ion or Lead Acid battery capable of high discharge. If your power supply is weak, the motor will "stutter" or reset your microcontroller (like an Arduino) due to the sudden current draw when the motor starts.

  • Wheel Alignment: When using 150 RPM motors for a 4-wheel drive robot, ensure your chassis is perfectly aligned. Because these motors have high torque, any misalignment will cause the robot to drift to one side rather than moving in a straight line.

  • Noise Suppression: Solder a 0.1uF ceramic capacitor across the motor terminals. This reduces the electromagnetic interference (EMI) that can interfere with sensitive sensors like the VL53L0X ToF Sensor.

Package Includes

  • 1 x 150 RPM 12V Centre Shaft DC Geared Motor

Disclaimer

Actual RPM may vary by ±10% depending on the load and power source. Avoid applying sideways pressure to the shaft to prevent gearbox damage.
