Need DC motor having high holding torque

In summary, the conversation is about a project on Wireless robotic arm using microcontroller. The person is looking for a DC Geared Motor with specific specifications including low RPM, high starting torque, and high holding torque. Another person suggests using a worm drive on a standard small DC motor, which has high holding torque due to friction. They also recommend looking for hobbyist sites and supplies for robotic projects.

Hello Mates,

I m making my project on Wireless robotic arm using microcontroller. I need DC Geared Motor with following specifications:

1) low RPM.
2) High Starting torque.
3) High Holding torque.

Can any1 please help me in selecting motor ??

Sounds to me like you need a worm drive on a standard small DC motor. Worm drives 'gear down' dramatically and are not too efficient so the holding torque is very good (due to the friction). A small motor needs to rev high, so a >=10:1 reduction would be quite handy. I should think.

1. What is a DC motor and what is holding torque?

A DC motor is an electrical device that converts electrical energy into mechanical energy. Holding torque refers to the amount of torque or rotational force that a motor can maintain while stationary.

2. Why is high holding torque important for DC motors?

High holding torque is important for DC motors because it allows them to maintain their position and resist external forces, making them more stable and accurate in their movements.

3. How is holding torque measured for DC motors?

Holding torque is typically measured in units of torque (such as Newton-meters or ounce-inches) and can be calculated by multiplying the force applied to the motor shaft by the distance from the center of the shaft to the point where the force is applied.

4. What factors affect the holding torque of a DC motor?

The holding torque of a DC motor can be affected by various factors, including the design and construction of the motor, the type and strength of the magnets used, the amount of current flowing through the motor, and the load on the motor.

5. How can I choose the right DC motor with high holding torque for my application?

When selecting a DC motor with high holding torque, it is important to consider the specific requirements of your application, such as the desired speed and torque, the size and weight limitations, and the power source available. You may also consult with a motor specialist or refer to motor specifications and performance charts to find the best fit for your needs.
