The torque of motor can be increased by internal rotor resistance, external rotor resistance, and variable voltage or frequency.
How to increase torque of DC motor?
Speed can be regulated in a gear box using different gear relations.
We increase the DC motor’s torque by changing the motor’s speed using the Gearbox. To increase the torque of the DC motor, we can use a gearbox to change the DC motor’s speed. By changing the speed of the motor, we can change the torque. As Power, speed and torque are connected, then with constant power, we can change the torque with the changing of speed.
So by using a gearbox, we can increase or decrease the output torque of the DC Motor.
How to increase torque of ac motor?
By internal rotor resistance increasing, torque of the ac motor can be increased.
We Increase the AC motor’s torque of the ac motor by three different methods: internal rotor resistance, external rotor resistance, and variable voltage or frequency.
We can increase the internal rotor resistance by decreasing the diameter or diameter of the rotor means cross-section area is reduced then internal rotor resistance is increased.
We can use a separate resistor to increase the external rotor resistance temporarily; by increasing this resistance, the motor’s torque can be increased.
The frequency of the motor can be changed by using the variable frequency drive; from that, by reducing the starting frequency, the AC motor’s torque of the ac motor can be increased.
How to increase the torque of an electric motor?
As we discussed above, we can change the speed of the motor by using a gearbox.
We increase the electric motor’s torque by using the different pulley drive systems by changing the speed. Like that, we can also use different pulley drives to change the motor’s speed. And we know that by changing the speed of the motor, torque can be increased with the same power input. We can use pulleys of different diameters to connect the input shaft and output shaft so we can have different speeds.
How to increase the torque of an electric motor?
The torque of the motor can be increased by following way
We increase the electric motor’s torque by using the different pulley drive systems by changing the speed.
BLDC motor (Brushless DC motor) is used in transportation, requiring higher torque. We increase the BLDC motor’s torque by changing the stator’s material. For example, ferrite material is more suitable as slots for the stator core. With this, stator loss can be reduced, producing higher voltage and lower current. So torque of the BLDC motor can be increased.
How to increase low end torque?
We Increase the low-end torque by changing the performance of some engine parameters. The rotational force produced at the low end in its operating speed range is known as low-end torque in the engine. We can increase this low-end torque by changing the flowing exhaust and intake system.
As the quality of sparks should be better for higher torque, we can increase the torque by installing some high-quality spark plugs. For that, to increase the low end torque, you should replace the ignition coil with a better one.
How to increase torque in a car?
We can use turbochargers or superchargers for higher compressed inlets with the car’s engine.
We increase a car’s torque by turbocharger or supercharger, adding the exhaust header and injector cleaner.
First, a Turbocharger or supercharger should be used to increase the torque in a car. As with high compressed air at the engine’s inlet, we can get faster combustion, so the engine can generate higher torque in starting.
With the engine, you can add an exhaust header to increase the engine’s torque. We know that if exhaust from the engine is not going well, it affects the combustion and indirectly affects the torque produced. So by adding the exhaust header, valves become wider so the exhaust will be better, chances of more fuel and air are possible in the next cycle, and torque can be improved.
Also, fuel injector cleaner, from time to time, changing the oil will be helpful to increase the torque.
How to increase torque with pulleys?
we can increase the torque at the output by increasing the diameter ratio.
We Increase the torque with pulleys by increasing the diameter ratio of the pulleys between two power transmitting shafts.
We can transmit the torque between two shafts through pulleys. This means with different diameters of pulleys, we can get various speeds of the shaft. And with constant power, we can get different torque on the Driven shaft. So by changing the diameter ratio, we can increase the torque with pulleys.
If we increase the diameter of the driving pulley, it will rotate more slowly than the driving pulley, but with the same power, the torque produced is more by the driving pulley than the driving pulley. So we can increase the torque at the output by increasing the diameter ratio.
V2 = V1(
V2 is the velocity of the driven pulley,
D1 is the diameter of the Driving pulley,
D2 is the diameter of the Driven pulley.
How to increase torque on wind turbine?
The torque on wind turbine can be increased by proper designing.
We increase the wind turbine’s torque by increasing the wind force and making the profile of the blade aerofoil.
As the wind comes towards the blade of the turbine, it should have a higher force, and then it can be converted into highertorque. Now, if the shape of the blade is aerofoil, then the wind force produced is more, so more torque can be generated.
How to increase torque without increasing horsepower?
we can change the torque produced. For increasing torque, speed should be decreased
We Increase the torque without changing horsepower by changing the speed of the rotor.
Now we know that Power, speed, and torque are related. And the relation of those is:
P = Horse Power, HP
N = Speed, rpm
T = Torque, Nm
Here it is clear that speed and torque are inversely proportional to each other without changing the horsepower. This means with changes in speed; we can change the torque produced. For increasing torque, speed should be decreased.
In this article, different tools and techniques are described to increase torque in motor, car and turbine. It is also explained that how different parameter affect the torque.
