Motor circuits

The project involves a DC geared motor intended for use in a suitcase carrier. Two motors were purchased from Pololu at a cost of approximately $100. The selection process included discussions among team members, followed by consultation with Dr. Leo Stucco to identify motors with sufficient power for the application.

The DC geared motor selected for the suitcase carrier is designed to provide high torque at low speeds, making it suitable for moving heavy loads such as luggage. The gearing mechanism reduces the motor's output speed while increasing its torque, which is essential for effective movement in the intended application.

Key specifications that should be considered for the motor include the voltage rating, current draw, gear ratio, and stall torque. The voltage rating should match the power supply available in the suitcase carrier system, typically around 12V for such applications. The current draw indicates the amount of power required under load, and it is crucial to ensure that the power supply can handle this demand without overheating or causing voltage drops.

The gear ratio is a critical factor that determines the motor's output speed and torque. A higher gear ratio will provide greater torque but lower speed, while a lower ratio will yield higher speeds but less torque. The selection of an appropriate gear ratio depends on the weight of the suitcase and the desired speed of movement.

Stall torque is another important parameter, as it indicates the maximum torque the motor can produce when starting from a standstill. This value should be greater than the maximum load torque required to move the suitcase to avoid stalling during operation.

The integration of the motors into the suitcase carrier will require careful consideration of the mounting configuration and the connection to the power supply and control system. It is advisable to implement a motor driver circuit that can handle the current requirements and provide control over the motor's direction and speed.

Additionally, implementing feedback mechanisms such as encoders can enhance the control of the motor's position and speed, allowing for more precise operation. Overall, the successful implementation of the DC geared motors will significantly enhance the functionality and usability of the suitcase carrier.Below is the DC geared motor that we will use to run the suitcase carrier. We bought two motors from Pololu which costs around $100. We had discussed possible motors within the group and then we sought out help from Dr. Leo Stucco.
