Define slip and synchronous speed of 3 phase induction motor.
A 3 φ I.M. has synchronous speed of 250rpm and 4% slip at full load. The rotor has a resistance of 0.02Ω/ph and stand still reactance of 0.15Ω/ph. Calculate i) The speed at which max torque is developed. ii) The ratio of maximum to F. L. torque. iii) The ratio of maximum to starting torque.
What is the importance of the synchronous speed in the operation of an induction motor?
What is the maximum speed of a synchronous motor?
What is the speed of a synchronous motor?
What is synchronous speed in AC machines?
What happen when Induction motor run at synchronous speed?
Three phase induction motor can never run on synchronous speed. Justify.
Why is a synchronous motor a constant speed motor?
State why three phase induction motor never runs on synchronous speed.
Define synchronous speed and slip speed.
What is the formula for synchronous speed? Answer : The formula for **synchronous speed** (\(N_s\)) of an electric motor is given by: \[ N_s = \frac{120 \times f}{P} \] Where: - \(N_s\) is the synchronous speed in **RPM ( ... s the theoretical speed at which the motor's rotor would rotate if there were no losses, such as friction or slip....
Which speed is called synchronous?
What is the unit of speed?
What is the SI unit of magnetic field?
What is SI unit of density?
What is V in SI unit of mobility?
What is the SI unit of AC conductivity? Answer : The SI unit of AC (alternating current) conductivity is the **siemens per meter (S/m)**. Conductivity is a measure of a material's ability to conduct electric current, and since it's the reciprocal of ... length of the material. So, in short, the SI unit of AC conductivity is **S/m**....

What is the SI unit of moving coil galvanometer? Answer : The SI unit of a moving coil galvanometer is the **ampere (A)**, since a moving coil galvanometer is primarily used to measure electric current. The instrument itself doesn't have a specific ... the readings from the galvanometer are typically in amperes, which is the SI unit of electric current....
What is the SI unit of voltage sensitivity?
What is the SI unit of galvanometer constant?
What is the SI unit of deflection of galvanometer? Answer : The SI unit of deflection of a galvanometer is not directly defined, as deflection is a *dimensionless* quantity. It's usually measured in terms of an angular displacement, which is typically expressed ... displacement (radians)** or **scale divisions**, depending on the design of the galvanometer....
