Posted on September 23, 2018

Understanding the importance of Torque-Speed curve and load .Applications like Pumps have low inertia and application like Fan and crushers are with high inertia. There is also a myth that the motor inertia should be equal to load inertia. There is no relationship between motor inertia and load inertia, except for some very special application and purposes.

In order to effectively design with D.C. motors, it is necessary to understand their characteristic curves. For every motor, there is a specific Torque/Speed curve and Power curve.

### Torque-Speed Curve - UTK-EECS

When the motor is stalled, i.e. locked-rotor condition, the current is 5-6 times the full-load current, making I2R losses 25-36 times higher than normal, so the rotor must never remain locked for more than a few second. • Small motors (15 hp and less) develop their breakdown torque at about 80% of n.

be additionally generated within the rotor, requiring an increase of slip and consequently a decrease of speed. As may be observed from Curve 1 of the speed- torque diagram, the torque behaviour of a slip ring motor with resistors short circuited, corresponds to that of a normal squirrel cage motor. On starting up, the torque.

Speed/torque characteristic. The speed/torque characteristic of a turbine is well matched to the requirements of a shredder, in that a reduction in speed due to increased load results in an increase in available torque as the speed governor provides more steam. Even with the steam control valve wide open, the available.
