Core Structure and Operating Principle

Stator

The stator generates a rotating magnetic field when powered by a three-phase supply. It provides the foundation for efficient energy conversion.

Rotor

The rotor interacts with the stator’s magnetic field to create torque. Depending on the load conditions, the rotor maintains synchronous operation, ensuring consistent speed.

Excitation Device

The excitation system of the motor is typically controlled by a silicon-controlled rectifier (SCR). This method provides reliable control over excitation current, ensuring stable synchronization during operation.

Key Characteristics

Feature	Description
Excitation Method	Silicon-controlled rectifier (SCR) for precise control
Starting Mode	Direct full-voltage start or reduced-voltage start (as required)
Dynamic Current Relationship	Proportional to the applied terminal voltage

Starting Methods and Performance

Direct Full-Voltage Starting

The motor allows direct starting at full terminal voltage. This method provides high starting torque and is suitable when the power grid capacity permits.

Reduced-Voltage Starting

If the power grid cannot support direct full-voltage starting, reduced-voltage starting is recommended. This method lowers the inrush current, protecting both the motor and the electrical system.

Relationship Between Current, Voltage, and Torque

One of the key performance characteristics of the T SERIES THREE-PHASE SYNCHRONOUS INDUCTION MOTOR is the proportional relationship between current, torque, and terminal voltage during startup.

100%	100%	100%
80%	80%	64%
60%	60%	36%
40%	40%	16%

Dynamic current is directly proportional to the terminal voltage.
Starting torque is proportional to the square of the terminal voltage.
