What are the speed torque characteristics of induction motor?
The torque-speed characteristics of a 3-phase induction motor is defined as the curve plotted between torque developed and rotational speed of the motor. It gives the information about variation in the motor torque with the change in its speed.
What are the characteristics of load torque?
Most of the industrial loads can be classified into the following 4 general categories:
- Constant torque type load.
- Torque proportional to speed (generator type load)
- Torque proportional to square of the speed (fan type load)
- Torque inversely proportional to speed (const power type load)
What is the relationship between speed and torque?
The relation between torque and speed are inversely proportional to each other. The torque of a rotating object can be mathematically written as the ratio of power and angular velocity.
What is the nature of the speed torque characteristic of a DC motor with constant excitation?
1. The nature of the speed-torque characteristics of a DC motor with constant excitation is described by a linear –ve slope graph.
What type of load torque characteristics does the rolling mills exhibit?
2. Rolling mills exhibit what type of load torque characteristics? Explanation: Rolling mills are an example of non-linearly decreasing torque characteristics because torque and speed exhibits inversely proportional relationships and power are constant.
What is speed torque characteristics of DC shunt motor?
CHARACTERISTICS OF DC SHUNT MOTOR Torque increases linearly with armature current. It’s seen that armature current is decided by the load, as load increases,>> Armature current increases >> Increasing the torque developed linearly.
How is torque related to speed?
Does speed increase with torque?
In terms of acceleration, torque plays a bigger role in how quickly your car accelerates. That’s because the torque is a result of the force the pistons generate and at what speed. The quickest vehicles can generate high levels of this torque force at relatively low rpm. This allows the vehicle to accelerate quickly.
