3 Phase Synchronous Machine

SKU: 3 Phase Synchronous Machine 50869009

Educational Motors & Machines


Product Description:

Synchronous motor belongs to the family of 3Phase Induction motors, with the difference that the rotor is not same as Induction motors instead has windings with slipring & slipring holder on the rotor. These motors have damper winding to make it start like Induction motors. These motors have 2 Types of Voltage Excitation, 3Phase for starting the motor & additional 110V DC across the rotor to lock the speed of the motor- Once it is excited with DC Voltage the rpm of the motor gets locked, in the sense that if the motor is running on No load or Full load the rpm remains the same. The application of such motors is those machines which run only on fixed speed without any rpm change, sugar mills & textile color mixing. This Model is the Industrial/Educational model suitable for demonstrating to students the complete know of the Basics, Components, Starting methods, DC Speed locking, Speed-Torque behavior, 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 viz Starting methods, Speed control, Speed-Torque, Speed locking, Effect of rotor excitation, Effect of voltage imbalance operation, Blocked rotor test.
