Can a torque in a motor be increased?
To increase the torque … that a bit harder. All you can do, electrically (as you can do it mechanically via gears), is to reduce the source impedance to maximise the current that can be delivered for a given stator impedance. Rewind it with more turns of thinner wire.
How do I make my torque higher?
An effective modification that will increase torque significantly is to install a turbo or supercharger. Forced induction forces air into your engine, increasing the power the engine provides. Depending on the torque curve you prefer, a turbocharger will need time to spool before it provides torque benefits.
What affects the torque of an electric motor?
Since the rated output power of a motor is a fixed value, speed and torque are inversely related. As output speed increases, the available output torque decreases proportionately. As the output torque increases, the output speed decreases proportionately.
How do you create torque in a motor?
An induction motor develops torque by inducing current to the rotor, which is proportional to the differential speed of the rotor and the rotating magnetic field in the stator. For NEMA design B motors the differential speed (called slip) is between 1% and 2% at full load.
How do you get more torque from an electric motor?
The way to increase the torque that the motor delivers, mechanically, would be:
- To increase the diameter of the wire in the windings (which is to say, completely remanufacture the motor)
- to have the output shaft coupled to a gear reduction setup, which would lower the final drive rpms, but increase the torque.
Does cold air intake increase torque?
The increased combustion that results from using a cold air intake means more horsepower and torque. This means your car will have better throttle response, horsepower gain, and be able to tow more weight.
Can you increase torque without increasing horsepower?
You cannot have horsepower without torque, but you can have torque without horsepower! … The most simple means of increasing torque is to run an open exhaust and intake and tune properly. Torque value will increase right along with HP, so long as the tuning is performed properly.
What is torque in AC motor?
Torque is the turning force through a radius – with the units Nm in the SI-system and the units lb ft in the imperial system. The torque developed by an asynchronous induction motor varies when the motor accelerates from zero to maximum operating speed.
How much torque does my motor need?
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.
How is torque transferred?
A gear’s transmission torque changes as it increases or decreases speed. Generally, by reducing the speed, a small torque at the input side is transmitted as a larger torque at the output side. The calculation of torque depends on the number of teeth.
