Star delta starter is a type of motor starter used to reduce the starting current of a motor.
Consists of three contactors and a timer
Initially, the motor is connected in star configuration to reduce the starting current
After a set time, the motor is switched to delta configuration for normal operation
Used for high power motors
Reduces voltage drop and prevents damage to the motor
Star delta starter circuit is used to reduce the starting current of induction motors.
The circuit consists of three contactors, a timer, and an overload relay.
During starting, the motor is connected in star configuration to reduce the starting current.
After a set time, the motor is switched to delta configuration for normal operation.
The overload relay protects the motor from excessive current.
Example: A 3-phase induct...

Synchronous motors operate at a constant speed determined by the frequency of the power source.
Synchronous motors have a rotor that rotates at the same speed as the rotating magnetic field in the stator.
They are used in applications where constant speed is required, such as in industrial processes or power generation.
Synchronous motors are more efficient than induction motors at higher loads.
They require a separate DC ...
Induction motors rely on induction to produce torque, while synchronous motors require a magnetic field to rotate at a constant speed.
Induction motors do not require any external connections to the rotor, while synchronous motors need a DC power source to create the magnetic field.
Induction motors are self-starting, while synchronous motors require external means to start.
Induction motors are more commonly used in indu...

A motor is a device that converts electrical energy into mechanical energy to perform work.
Motors are commonly used in various applications such as electric vehicles, industrial machinery, and household appliances.
They come in different types such as AC motors, DC motors, and stepper motors.
Motor capacity refers to its power rating, typically measured in horsepower (HP) or kilowatts (kW).
Higher capacity motors can gene...

HT motor rating is the maximum power it can handle and FLC is the current it draws at full load.
HT motor rating is expressed in kilowatts (kW) or megawatts (MW).
FLC of HT motor is the full load current it draws at rated voltage and frequency.
FLC is expressed in amperes (A) and varies depending on the motor's power rating and efficiency.
For example, a 1 MW HT motor may have a FLC of 1000 A at 11 kV.
The rating and FLC of...
