Question

what will happen if we place high torque motor and high speed motor together.. Will the speed increase or torque increase??​

Answer 1

Answer:

Main Entry: torque

Function: noun

Etymology: Latin torquEre to twist

1 : a force that produces or tends to produce rotation or torsion (an automobile engine delivers torque to the drive shaft);

also : a measure of the effectiveness of such a force that consists of the product of the force and the perpendicular distance from the line of action of the force to the axis of rotation

2 : a turning or twisting force

Answer 2

Explanation:

As given in one of the answers, there's no such thing as not being able to run the motor above its rated speed. The thermal capacity of the motor decides at what speed it can run and for how long. Now, concerning the question of what exactly happens if the motor is run above rated speed, look at the following diagram

The diagram describes torque speed characteristics of a DC motor, however the same (or similar) is applicable to almost any electric motor.

1) The knee point here gives the rated speed

2) After the knee point the back EMF of the motor (which is directly proportional to the speed) increases such that the motor is no longer able to maintain the current supply. Any increase in current would require a proportional increase in supply voltage, which is generally fixed. Hence after this point the motor operates in constant power mode (The back EMF keeps on increasing and the current keeps on reducing)

3) As the current is reducing continuously, the motor torque also reduces in proportion.

To conclude, with speed increase beyond the rated speed, torque reduces, power remains constant. This continues till the maximum permissible speed, operation beyond which causes damage to the motor (Thermal and Mechanical).
