A torque motor is a specialized form of DC electric motor which can operate indefinitely while stalled, without incurring damage. In this mode of operation, the motor will apply a steady torque to the load (hence the name). A torque motor that cannot perform a complete rotation is known as a limited angle torque motor.
Why is torque important in a motor?
Torque is a crucial part of generating power from a car’s engine, as it represents the load an engine can handle to generate a certain amount of power to rotate the engine on its axis. … Multiply this torque force (in lb-ft.) by the axis’s rotational speed per minute (RPM) and you get the engine’s power output.
What is meant by torque in motors?
Torque is a twisting force that speaks to the engine’s rotational force and measures how much of that twisting force is available when an engine exerts itself. … This applies torque, or a twisting force, to the bolt. While horsepower is simply measured in horsepower, torque is typically measured in pounds feet (lb.
How does torque work in motor?
Torque is a rotating force produced by an engine’s crankshaft. The more torque an engine produces, the greater its ability to perform work. The measurement is the same as work, but slightly different. Since torque is a vector (acting in a certain direction), it’s quantified by the units pound-feet and newton-meters.
What can torque be used for?
The primary use of torque is to make the car accelerate, and the number usually quoted is the maximum torque of the internal-combustion engine at the crankshaft – and that’s usually higher than the amount at the wheels. … But it’s not just about speed, torque is also important when vehicles get heavier and larger.
What is better hp or torque?
Torque, simply, is the ability of a vehicle to perform work — specifically, the twisting force applied by the crankshaft. Horsepower is how rapidly the vehicle can perform that work. … Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms.
Why does torque drop at high RPM?
At high RPM, torque drops off primarily from intake and exhaust flow restriction. Volumetric Efficiency declines because the engine can’t breathe any faster. Mechanical efficiency also declines at higher RPM, due to increased frictional resistance. This further reduces torque at the output.
