AC Repulsion Motors
Sci-tech AC Repulsion motors belong to the family of Single phase motors with the difference that they have wound rotor, commutator & brush arrangement resembling DC motors. But the operation is same as single phase motors & the brush arrangement is provided for reversal of speed of motor.
AC Single PH SQUIRREL Cage Induction Motors
Sci-tech Single Phase AC Squirrel Cage Capacitor Start Induction motors are designed for Educational usage suitable for demonstrating to students the complete knowledge of the Basics, Components, Starting methods, Wear & Tear & Maintenance of these motors packaged in small rating. Students can make connections of their own with the help of the terminations provided for study of features like Starting methods, Speed-Torque, Effect of Phase angle, Study of Cogging/Crawling, Effect of reduced voltage, Blocked rotor test.
Sci-tech Single Phase AC Squirrel Cage Capacitor run Induction motors have a capacitor in its running winding this means the capacitor is always connected and active while the motor is running.
Alternators are the Power Generation Devices, converting mechanical energy into Electrical Energy. The electricity provided by our utilities is from some Power Generation center use Heavy Alternator that produce Electricity . Alternators have a design with wound rotor & wound stator. Alternators are available either with slipring holders as well as Brushless types. Students can make connections of their own with the help of the terminations provided for study of features like Single phase generation, 3Phase Generation, Regulation with change in Load, Effect of change of speed on output voltage, Effects of Field voltage excitation change.
We have latest technology, lightweight, aesthetically appealing, reliable with best performance.
The motors are highly engineered to cope up with sudden load variations, longer thermal life, higher altitude and wide voltage variations.

DC Motors : Series – Shunt – Compound
DC SERIES MOTORS
Sci-tech DC Machines have been the running horse for the Industry since 100 Years. Where ever Heavy Torque is required Series DC motors are the option, these motors need load to start, these motors have the tractive effect & are even named as Traction motors, for applications like railways, material handling machines etc
DC SHUNT MOTORS
Sci-tech DC Shunt Machines have been the running horse for the Industry since 100 Years, Shunt motors have been the most used due to their very simple speed control, ruggedness & High Torque capabilities.
DC COMPOUND MOTORS
Sci-tech DC Compound Machines have been the running horse for the Industry since 100 Years, Compound motors are one of these types.
Sci-tech Dynamometers are designed for testing rotating machines, AC as well as DC machines. The dynamometers are also indirect method of loading the machines. The construction features are primarily a DC Shunt Generator constructed in such a way that it is able to indicate the torque produced at the rated rpm and current for the machine coupled to it.
