Torque is a measure of how much a force acting on an object causes that object to rotate. Speed is how fast something is going. Another way to think of this is as how far you can go in a certain amount of time.

∙ 8y agoSpeed is a measure of how far something travels in a given period of time. The rate of change in position. For a motor, speed is measured in revolutions per minute.
Torque is force exerted as an object rotates. To turn a motor shaft requires a certain amount of torque. If a load is added to the shaft, more torque is required to turn it.
Two motors of different sizes may run at the same speed. A shaded-pole motor (example: window fan) exerts very little torque. A common speed is 1800 or 1200 RPM.
A large industrial motor (example; factory conveyor belt) may exert a very high torque in order to start a heavy load, and yet it runs at a similar speed.
The same is true of engines. An eight cylinder car engine can run at 3600 RPM and exert a great amount of torque. A small generator will run at 3600 RPM, but not exert nearly as much torque as the car.

What is the torque speed characteristic?
the ratio of the relative speed of stator magnetic field with the speed of rotor, to the speed of rotor is defined as slip. where as in torque slip characteristic is the graph between the speed of the rotor and the torque experienced on the rotor. in the case of induction motor, the torque decreases with the increase in the rotors speed. while in the case of sychronous motor, its different (you check out, because i just forgot about it!! keep smiling!
Performance curve of a single phase induction motor?
The performance curve can be a graph of torque versus speed. The torque is zero at zero speed and also at the synchronous speed. Normally an induction motor operates at 90-97% of the synchronous speed, where the slip is between 10% and 3%. In this region the torque is proportional to the slip. As the torque is increased the speed falls until the motor stalls and the speed drops to zero. Below the stalling speed the torque rises between zero speed and the stalling speed. Because the torque is 0 at 0, a single-phase induction motor needs a separate starting winding fed by a starting capacitor to produce a little positive torque that starts the motor.
Drawing of speed-torque curve for synchronous machine?
Theoritical torque speed curve for a synchronous machine will be a vertical line located vertical to the synchrounous speed at x axis, from starting torque to stalling torque value. This is because theoritically synchronous motors are not self starting. Practically however they start as induction motors and at near synchrounous speed the excitation is switched on. Anand Sekhar
What will happen to speed-torque characteristics of an induction motor is the rotor resistance is increased?
If Rotor resistance is increased torque is increased
Why use clutch plate in single phase motor?
induction motors have very little starting torque as the motor come up to speed it reduces the torque load until it gets near synchronous speed
What is the torque on a torque converter?
Torque output of the engine at that speed.
What is the relationship between torque and speed for an electric motor?
Torque and speed are inversely proportional
How the speed of a vehicle is related to engine speed and how tha vehicle speed is affected by the engine torque and gear ratio?
A smaller number as a gear ratio means more speed. Higher ratios have higher torque and less speed. The size of the engine just determines hp and tq for that engine unless it is upgraded. The gear ratio and engine determine the vehicles top speed and acceleration. More torque means more power therefore more acceleration.

What is difference between speed and torque?
speed= distance per seconds & torque= revolution per seconds
Explain Speed mode torque mode in variable speed drives in detail?
Torque mode in variable speed drives is where the drive adjusts its torque according to the input. The speed/velocity mode is where the input is used to control the motor's RPM.
What is ment by the term torque multiplication?
Torque multiplication is proportional to the difference in speed between the impeller and the turbine. for example : At an engine speed of 2100 RPM, and torque at that speed of 100 Newton meters, the torque input to the transmission will be 2.2 times that value - 220 Newton meters with help of torque multiplication.

How is torque related to power?
Torque is the cars power, horsepower is only the rate at which the torque is produced.
What are the uses of a gear train?
Either to increase speed and reduce torque or to decrease speed and increase torque while conserving mechanical energy.
What mechanism can increase torque speed?
the motor
Full load torque of induction motor?
full load torque is the torque which produces rated power at full speed
