Why three phase motor has the better performance when compare to single phase motor?

If you are asking what is the advantage of a motor wound for a Y or Delta configuration over a motor wound for a single phase configuration, then the advantage of the Y or Delta motor is more efficient operation. And in a motor, or in any power application, efficiency is all important.

∙ 14y agoSince the phases overlap, torque overlaps, and you need less rotating mass to stabilize the output load. Think of an eight cylinder engine versus a six, or a four. Its the same thing as a three phase power supply. The capacitors are smaller and the pre-regulator voltage ripple is smaller, with a higher frequency.

True, but the advantages outweigh that disadvantage.

How do you start single phase induction motor?
capacitive start motors start by themselves however a normal single phase induction motor requires a starter motor to 'kick-start' the motor into action.
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.

How does the VW GTI motor performance compare with other VW models?
The performance on the VW GTI model was ranked higher then other VW models. It was given 4 out of 5 stars in most cases but other VW models are still high in the ranking.

How do you check single phase motor winding?
Single phase motor winding is often checked just by listening to the noise that the motor is making. An experienced person can tell if the motor is working at single phase or double phase.
What oil for a Chevy 350?
10w-40 pre 89. After 89, 5w-30. For high performance, I would advise a single weight, that works best with the clearances you built into the motor.
What is difference between single motor unit and multi motor unit?
There is no 'multi motor unit' to be different from a single motor unit!A single motor unit is all the muscle fibers controlled by a single motor neuron.Multiple motor unit summation is when a smooth and steady increase in muscle tension is produced by increasing the number of active single motor units.Notice that what's being described is not something having to do with a some non-existent thing called a 'multi motor unit', but rather is a summation of many active singlemotor units.
