How can you increase the torque of an electric motor without increasing the speed?
keep the same winding configuration or number of poles increase the diameter of the rotor and stator
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!
What type of motor has a stator?
An electric motor has a stator and a rotor. The stator does not move. The rotor rotates inside the stator.
Who to increase torque of ac motors?
ac voltage
How is pull out torque developed?
With some motor designs, as the motor starts to accelerate, its torque tends to fall somewhat before starting to increase again. The point of lowest torque in this region of the curve is termed the 'pull-up torque'.
How can you increase the torque of an electric motor without increasing the speed?
keep the same winding configuration or number of poles increase the diameter of the rotor and stator
Why is the number of poles of stator and rotor same in induction machine?
The number of poles on stator and rotor is always the same. If they are not equal?æno torque will be produced, thus, the machine will not function.?æ
How does a torque converter amplify the torque?
The stator inside the torque converter directs the fluid at an angle to trans. part of the torque converter amplifying the force on the vanes.

How does an induction motor develop torque?
The shaft of an AC induction motor rotates because of the torque created by the interaction between the magnetic field of the stator and the magnetic field of the rotor.
How much minimum torque is required by a turbine to generate Electricity?
initial torque to overcome the friction in generator and then to keep constant speed of stator within the generator. Minimum 50NM
What is the effect of increasing the length of the air gap in an induction motor?
The magnetic flux that couples the rotor to the stator will weaken significantly reducing the motor's torque.
Why is there a metal ring on the out side of the torque converter shaft on a Chevy turbo 350 transmission?
If you are talking about the splined ring around the input shaft, it's for the torque converter stator. The stator is like a second set of fan blades inside the converter that redirect fluid to the blades that turn the input shaft. It greatly increases the efficiency of the torque converter, which is actually a fluid coupling. In order to do it's job, the stator must be held stationary, that's what the splined ring is for. Hope that makes sense. It's not easy to explain.
How can you increase torque?
When you increase horsepower, there's typically a torque increase which goes along with it. You could also replace your rear end gears with taller gears.
What is the operating principle of thyromat control system for cranes?
The THYROMAT is connected in series with the stator supply voltage. The control unit varies the stator voltage of the slip-ring motor by adjusting the firing angle of the inversely connected (parallel) thyristors in each of the three phases. The motor torque is proportional to the square of the stator voltage (T a V2 - where T is the motor torque and V is the stator voltage). The speed of the motor is measured by the frequency of the rotor. Reversing the direction of motor rotation is achieved by switching externally mounted reversing contactors at zero current.
What mechanisms can increase torque?
the motor
What mechanism increase torque?
