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.

What is the torque of 1 hp motor?
Three Phase 720 Rpm 1 HP Torque Motor
|Voltage||415 V +/- 10%|
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.
