Defintion

Torque -- also called MOMENT OF A FORCE, in physics, the tendency of a force to rotate the body to which it is applied.

The torque, specified with regard to the axis of rotation, is equal to the magnitude of the component of the force vector lying in the plane perpendicular to the axis, multiplied by the shortest distance between the axis and the direction of the force component. Regardless of its orientation in space, the force vector F can always be located in a plane parallel to the axis.

What is the major advantage of a compound DC generator?

The compound DC motor has the advantage of both, constant speed feature of the shunt motor and the capability to handle high starting torque feature of series motor.


What is the relationship between torque and speed for an electric motor?

Torque and speed are inversely proportional


What happens to speed when toque increases in bldc motor?

When torque increases in a BLDC motor, the speed decreases. This is because as more torque is applied, the motor has to work harder to maintain the same speed. The relationship between torque and speed is inversely proportional in BLDC motors.


Performance curve of a single phase induction motor?

The performance curve can be a graph of torque versus speed. The torque is zero at zero speed and also at the synchronous speed. Normally an induction motor operates at 90-97% of the synchronous speed, where the slip is between 10% and 3%. In this region the torque is proportional to the slip. As the torque is increased the speed falls until the motor stalls and the speed drops to zero. Below the stalling speed the torque rises between zero speed and the stalling speed. Because the torque is 0 at 0, a single-phase induction motor needs a separate starting winding fed by a starting capacitor to produce a little positive torque that starts the motor.


What happens if load torque is same at full speed in separately excited dc motor?

Same as what? at maximum speed and torque, the motor delivers maximum power.


What will happen to motor when the torque of the motor is decreased?

flux linkage decreases due to that torque decreases and so speed will decreases


What is the torque speed characteristic?

the ratio of the relative speed of stator magnetic field with the speed of rotor, to the speed of rotor is defined as slip. where as in torque slip characteristic is the graph between the speed of the rotor and the torque experienced on the rotor. in the case of induction motor, the torque decreases with the increase in the rotors speed. while in the case of sychronous motor, its different (you check out, because i just forgot about it!! keep smiling!


Full load torque of induction motor?

The full load torque of an induction motor is the maximum torque it can produce at its rated speed when operating at full load conditions. This torque is necessary to drive the load at the desired speed under normal operating conditions. It is an important parameter to consider when selecting a motor for a specific application.


What are the advantages of induction motor?

1. Induction motor has high starting torque, therefore use for operate pump which need high starting torque. 2. Induction motor operate on variable speed. 3. It can be used as generator when speed of motor is higher than synchronous speed.


What mechanism can increase torque speed?

One way to increase torque speed is by using a gearbox or gear reduction system. By changing the gear ratio between the input and output shafts, you can increase the speed of the output while reducing the torque. Additionally, increasing the voltage supplied to a motor can also increase its torque speed characteristics.


What type of dc motor is suitable for variable torque operation?

A shunt-wound DC motor can maintain its speed well when the load torque varies.
