150 RPM 12V Centre Shaft DC Geared Motor High Speed Metal Gearbox Robotic Motor

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.

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