DC motor (BO) Battery Operation. Dc motor converts electrical energy into mechanical energy. Why DC gear motor used in robot Motor control circuit. DC MOTOR concept is where gears reduce the speed of the vehicle but increase its torque is known as gear reduction. In DC motor is assembled with multiple gear setup. Speed of motor is counted in terms of rotations of the soft per minute is called RPM. RPM means Revolution Per Minute. The setup assemble helps to increasing the torque and reduce the motor speed. All micro-controller based Robots this type of DC motor can be used.
In any DC motor, RPM and Torque is inversely proportional. In all DC gear motor PWM Pulse Width modulation circuit is used.
HOW TO SELECT DC MOTOR.
For light weight robot required low power plastic gear DC motor.
RPM: 60 TO 300.
Voltage:2 DC to 12 VDC.
300 RPM low cost single shaft straight DC gear motor. Most suitable for light weight robot.
Motor runs smoothly for 2V to 12 VDC and gives wide range of RPM and Torque.
