What is the maximum speed of an induction motor?

practically, the Motor can be run at 3492 RPM at 60 Hz.

What is the maximum speed of induction motor in India?

Motor Type: 3 Phase AC Electric Induction Standard Motor. Speed: Upto 3000 RPM. Power Rating: Upto 90 KW. IP Rating: IP44 & IP55.

What is the maximum speed of a motor?

The most common speeds of electric motors are 3000RPM for 2 pole asynchronous motors. If connected to frequency drives and the motor is designed mechanically for higher speeds they can go to 6000RPM.

What is the maximum speed of single phase induction motor?

Standard synchronous speeds available are; 900, 1,200, 1,800, and 3,600 rpm. An induction motor turns slightly slower than a synchronous motor and takes the form of a squirrel-cage motor. The reduction in speed is called motor slip.

What is synchronous speed of an induction motor?

Synchronous speed is the speed of rotation of the magnetic field in a rotary machine. An induction motor always runs at a speed less than synchronous speed. The rotating magnetic field which is produced in the stator will generate flux in the rotor which will make the rotor rotate.

What is the maximum synchronous speed in India?

Motor Speed Indian motors have synchronous speeds like 3000 / 1500 / 1000 / 750 / 600 / 500 / 375 RPM corresponding to no. of poles being 2, 4, 6, 8, 10, 12, 16 (always even) and given the mains frequency of 50 cycles / sec.

How is the speed of an induction motor determined?

In most cases, you can look inside the motor and count the number of poles in the winding; they are distinct bundles of wire evenly spaced around the stator core. The number of poles, combined with the ac line frequency (Hertz, Hz), are all that determine the no-load revolutions per minute (rpm) of the motor.

What determines the speed of an induction motor?

Every ac induction motor has poles, just like a magnet. The number of poles, combined with the ac line frequency (Hertz, Hz), are all that determine the no-load revolutions per minute (rpm) of the motor.

When the speed of the rotor is the synchronous speed?

But due to the lagging of rotor flux current with respect to stator flux current, the rotor will never reach its rotating magnetic field speed i.e. the synchronous speed. If the motor is running at synchronous speed, then the torque generated by the motor equal to zero.

What is synchronous speed and rotor speed?

The synchronous speed refers to the stator rotating magnetic field, which depends on the number of poles and frequency. The other speed is the rotor’s. The rotor speed will be always slower than the stator speed, we call it slip. The induction motor must run at a speed below the revolving stator field flux.

What is the rotor resistance of a 2 pole induction motor?

A two-pole, wound rotor, induction motor has a rotor resistance of 0.8 ohms per phase and a rotor leakage reactance of 7 ohms. At what speed will the motor produce maximum torque when fed from a 50 Hz supply?

What is the maximum speed of a 3 phase induction motor?

So if you have a three phase induction motor, the maximum speed can be obtained by taking a 2-pole motor and driving it from a variable frequency drive (VFD). If you set your VFD maximum speed to 120Hz (obtainable in many VFDs), then your two pole rotor (unloaded) will honk along at 7200 r.p.m.

What is the maximum speed of a rotor?

Rotor speeds typically lie in the 120–210 m/s range, but mostly between 150 and 190 m/s, with a tendency to be higher with a smaller rotor diameter [ 6 ]. Currently the smallest rotor diameter used industrially is 28 mm with rotor speed up to 150,000 rpm, though some machines can reach 160,000 rpm.

What is the maximum speed for a 6 pole motor?

The only “rule of thumb” I have heard and adhere to, is that the mechanical speed limit of any manufacturers design, without consultation directly with them, is the 2 pole speed. So in your case roryrob, your 6 pole motor could be taken up to 3600RPM, which would mean 180Hz.
