Apart from the current through the coil the torque depends on the magnetic field strength. Usually DC motors have permanent magnets ( most commonly used are AlNiCo or SmCo magnets), a higher grade or strength of permanent magnets (like NdFeB) will produce a much higher torque.

## What two factors determine the amount of torque developed by a DC motor?

What two factors determine the amount of torque developed by a DC motor? **The strength of the magnetic field in the armature, and the strength of the magnetic field in the poles.**

## On which factors torque of a DC motor depends?

Answer : Torque developed by a D.C. motor depends upon **magnetic field, active length of the conductor, current flow through the conductors, number of conductors, radius of armature**.

## What determines the speed regulation of a DC motor?

The **speed regulation of a DC motor** is proportional to the resistance of the armature. The lower the armature resistance the better the **speed regulation**. The reason for this is that armature current **determines** the torque produced by **motor** if field excitation remains constant.

## How do you increase torque in a motor?

## How is rated torque calculated?

To calculate load torque, **multiply the force (F) by the distance away from the rotational axis**, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.

## What is high torque DC motor?

A torque motor is a specialized form of DC electric motor which can operate indefinitely while stalled, without incurring damage. … Brushless torque motors are available; elimination of commutators and brushes allows higher speed operation.
