What does a torque curve show?

plots the torque of a motor against the speed the motor is going at. The relationship between speed and torque varies dramatically across different types of motor and also between manufacturers.

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.

How does torque affect engine performance?

In terms of acceleration, torque plays a bigger role in how quickly your car accelerates. That’s because the torque is a result of the force the pistons generate and at what speed. The quickest vehicles can generate high levels of this torque force at relatively low rpm. This allows the vehicle to accelerate quickly.

Why is stall torque important?

You should care because stall torque is the highest point of failure on a drive unit or a motor. The device is going to draw a lot of current at stall. In fact, it’s going to draw the highest amount of current you’ll ever see while under normal operating conditions. The keyword there being normal operating conditions.

What is the importance of torque?

An engine’s power is the product of force and the speed with which this force acts. Engine power and torque are both indicators that depend on the engine speed. A high torque enables efficient and energy-saving driving. A high engine power enables a car to accelerate quickly and reach a high top speed.

How does gear increase engine torque?

You can in increase the torque by reducing the speed with gears. Or reduce the torque and increase the speed.

Do electric motors have a torque curve?

Electric vehicle torque delivery As a current flows through the electric motor, a related electrical charge causes an armature to rotate. This explains why the torque curve begins to diminish on an EV dyno graph as the car’s electric motors are pushed into the upper ranges of their performance limits.
