Induction motors run at sub synchronous speeds because the slip (difference between synchronous and actual speed) causes, or controls the electric field strength in the motor. As more load is put on the motor, the motor's speed decreases, increasing slip, and increasing the electric field strength.

Do you need starter for 0.5HP three phase induction motor?
You never need a starter for a three-phase motor.
Why induction motor speed is always less then synchronous speed?
induction motor never runs at synchronous speed, if it does so there would not be any relative speed between stator flux and rotor and no emf will induce in rotor and we can not apply motor principle as we need current carrying conductor in magnetic field.
Why an induction motor will never run at synhoronous speed?
An induction motor relies on low-frequency currents induced in the rotor by the difference in speed between the rotor and the rotating magnetic field. At sychronous speed the induced current is zero therefore the torque is also zero.
How can an induction motor act as perpetual motion machine?
Perpetual motion machines are an impossibility. Energy conversion is never 100% efficient. Even if it were, friction is never zero.
How do you wire a three phase motor with capacitor start?
I have never come across a three phase capacitor start motor. Any three phase motors I have worked on are induction start.
What happens when ac is given to dc machine?
when we give d.c to an a.c motor i think there will not producing rotating magnatic field in case of induction motor so it never rotate and another dangeres issue is that there will burning of stator winding because constent flux producing in here so it does not link rotor winding
Why Single phase induction motor produces more noise as compaired to three three phase?
Never heard of this before. Any noise that comes from a motor is usually produced by faulty bearings, loose end bells or cooling fan becoming loose from the armature shaft. When a bearing fails the armature is allowed to drag on the stator and this produces noise and heat with motor winding failure not far behind if left unchecked. The overload protection should trip to try and save the motor but constant resetting will finally do the motor in.
Can a 208 415 motor run on 230?
never heard of a 415 motor..
What is the Definition of continious duty motor?
A continuous duty motor is one which is never turned off.
What motor must be never run without a load connected to them?
DC Series motor should never run without load connected to it because starting torque for DC series motor is infinite and running it on no load will damage the motor due to overspeeding.
Why is it impossible for induction motor to operate at synchronous speed?
Torque is produced because the rotating magnetic field, set up by the stator windings, cut and induce voltages into the rotor bars. The fields set up by the resulting rotor-bar currents then interact with the rotating field, causing the rotor to turn. If the rotor turns at the same speed as the rototing field, then its bars will not be cut by the field, there will be no induced voltages, no bar currents, and the torque will disappear.
Have a 05 Ford f150 will a 350 Ford motor fit in it?
Ford never made a 350 motor
