Are you considering torque when selecting DC motors? If so, we are right here to provide you with all the help and give you some advice before investing. A DC motor is powered through a direct current, meaning the current flows in one direction only. When we select to use which electric motors, the torque needed becomes one of the parameters to be considered. 

The definition of DC motor torque

A torque motor is a specialized form of DC electric motor which can operate indefinitely while stalled, without incurring damage. In this mode of operation, the motor will apply a steady torque to the load (hence the name). A torque motor that cannot perform a complete rotation is known as a limited angle torque motor.

A high torque DC motor offers a high starting torque, which makes it perfect for use in applications that are designed to move heavier loads, such as wiper systems, and in industrial automation applications, such as conveyor systems or materials handling equipment. The consistent drive power that DC motors deliver means they’re ideal for maintaining a constant torque while an application is in use, making them an excellent choice for a geared motor solution.

When the DC motor doesn’t include a gearbox, DC motor torque is different from DC geared motor torque. Gears make it possible to reach higher torque.

High torque geared DC motor

Just as the name indicates, sometimes, if requiring high torque, the motor should be geared. When a rotary machine such as an engine or electric motor needs the output speed reduced or torque increased, gears are commonly used to accomplish the desired result. The gear ratio expresses the ratio of the output torque to the input torque.

Thus, we can multiply the torque supplied at the motor shaft (the input) by the gear ratio to find the torque at the wheel axle (the output). Transmitting power through a series of gears can also affect rotational speed. In other words, when a rotary machine such as an engine or electric motor cannot provide the desired output speed or torque, a gear reducer may provide a suitable solution.
