What Is the Squirrel Cage Induction Motor Set Used For?
The three-phase squirrel cage induction motor is the workhorse of industry: its rotor is a cage of bars shorted by end rings, with no brushes or slip rings, and it turns because the stator’s rotating magnetic field induces currents in those bars. A lab set like this one lets an electrical machines class wire up such a motor, start it and observe its line voltages, current and running behaviour on a real three-phase supply.
Frequently Asked Questions
What does D.O.L. starting mean?
Direct-on-line: the starter switches the full line voltage onto the motor in one step. The motor then draws a starting current several times its full-load current for a short time, which is acceptable for small motors of this size and is the simplest way to start a squirrel cage machine.
Why are six terminals brought out?
Both ends of each of the three stator phase windings are available, so the windings can be connected in star or in delta at the terminal box, and the effect of the connection can be studied.
What is the voltmeter selector switch for?
Its Off/RY/YB/BR positions let one voltmeter read each of the three line-to-line voltages in turn, so the supply can be checked for balance without a second meter.
What does TEFC mean?
Totally enclosed fan cooled. The motor’s enclosure keeps dust and moisture out, and a fan on the shaft outside the enclosure blows air over the frame to carry heat away.
Why is the rated speed 1440 RPM?
An induction motor always runs a little below the synchronous speed of its rotating field. That small difference, called slip, is what lets the field cut the rotor bars and induce the current that produces torque; it grows slightly as the load increases.
How does it differ from the Thyristor/IGBT Controlled AC Motor With VVVF Control?
This set starts its motor direct on line through a D.O.L. starter. The VVVF setup starts and controls an AC motor through a thyristor/IGBT AC drive.
What details should an export enquiry give?
The number of motor sets, the destination country and port or city, the delivery terms you want (for example FOB or CIF), packing or labelling requirements, and any tender reference.
Who supplies this motor set?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, in Ambala, Haryana, supplies it and sends the quotation.
